Placing the ENT microscope on the ground and moving it around as and when required is a matter of comfort and convenience. ENT specialists have to move around to get the closest look and for this the ergonomics and product design of the microscope must be brilliant. It increases productivity and reduces stress as doctors have to do this on a regular basis. Rather than bending down every time one examines, the ENT microscope with its flexible, mobile handle can make it very convenient to stand at one place and reach the area needed.

5. Stage

While analyzing ears, nose or throats it is essential to take notes and look at references, slides, x-rays and scan reports to understand the present situation of the patient. Rather than reaching out to the reference every time or holding it one hand, one can pin it to the stage that comes with the ENT microscope.

6. Mount

ENT microscopes come in a variety of mounts; floor mounts, wall mounts, ceiling mounts and so on. Choose the mount that you find convenient for your practice and the one that’s preferred by most ENT specialists. Not just convenience, but also consider the feasibility of the installation and then buy the type of mount you want.

7. Camera

For easier observations and documentation of analysis a digital SLR, video camera and an observable screen would be very convenient. Few areas of ears, nose and throat cannot be reached by mere observation and requires something that can go inside. ENT microscopes with tiny digital SLRs can help in this regard, easily documenting and observing each patient.

Lab Microscopes for Diagnostic Use

Lab microscopes the early days medical science are being utilized to detect diseases. Various types of infectious diseases caused by tiny microorganisms like bacteria, viruses, fungi, and parasites are often diagnosed by investigating the body fluid as specimen under microscopic observation. Body fluid samples are taken by the doctors for laboratory analysis and investigation. Mostly based on the type of infection being suspected body fluid is taken from the patient’s body. This includes blood, urine, sputum, cerebrospinal fluid, and genital secretions. Observation carried out under lab microscope is a primary diagnostic method widely used for detecting diseases, especially the virus borne infectious ones.

The importance of microscopic examination in diagnosis

Microscopic examination plays an elemental role in providing a preliminary and tentative identification of infectious agents responsible for the disorders. The examination reveals the size, shape, and cellular structure of the infection in details. Treatment of the patient largely depends upon the result of these microscopic findings. In case of virus borne diseases the faster treatment is a crucial aspect to prevent spreading of the disease and to save the lives of the affected people. In this context quality microscopic findings help concluding on the state of the condition faster.

How microscopic tests are carried out

As we have already explained, body fluid from the infected person is taken for microscopic test. Gram stain test is the most common type of test in which the sample is smeared on microscopic slide and then it is stained with a special dye. This test is particularly used to classify all bacteria into two classes as per the stains. The blue staining ones will be called gram positive while the red staining ones will be called gram negative.

Another type of microscopic test called acid-fast smear requires spreading sample on a slide, dyeing it, and thereafter treating it with acid-alcohol solution. This test is used for identifying the acid-fast bacteria. The infectious bacteria will not be discolored by the acid-alcohol solution in this test. This is the common test used often for examining sputum. This test has widely been used for diagnosing tuberculosis.

Different types of microscopes used for diagnostic purposes

Microscopic technology over the years evolved to make better detection of microscopic organisms possible. This evolving capacity of microscopes also helped detecting lethal virus borne diseases and eliminating them with biological researches. Some of the common types of microscopes used in medical labs for diagnostic purposes include the following.

Light Microscopes

In this type of microscopes visible projected light is used to illuminate and magnify the specimen. This type of microscopes also varies in magnifying capacity and offers a range from the very basic to the advanced compound ones for e.g. dental microscope and ENT microscope. Compound microscopes are used for higher magnification and to obtain greater cellular details. Compound microscopes are also light microscopes, but they contain two types of lenses offering many hundred times better magnifying capacity. Among compound microscopes also there are specialized microscopes like dark field and phase contrast microscopes. These specialized microscopes are capable not only to capture live cells, but also to offer a magnified view of internal cell parts.

Fluorescent Microscopes

The fluorescent microscope which is also known as confocal microscope basically makes use of ultraviolet light as the main source of light. This microscope functions by emitting ultraviolet light on the objects and thus by exciting the electrons in it. The electrons emitting light in various colors helps identifying bacteria inside a living organism.

Electron Microscopes

In this type of microscope a beam of electrons are used as the source of light energy. The beam having an exceptionally short wavelength helps increasing the image resolution to a great extent. Several major breakthrough microscopic studies in medical science are carried out using this type of microscope. To capture the details of microscopic organisms in sharp contrast this microscope is especially useful. These microscopes fall in the specialized category of microscopes used in fields of biological research or for detecting certain viruses and bacteria responsible for infectious diseases.

X-Ray Microscopes

These microscopes, as the name indicate uses X-ray beam to create an image of the examined object. X-ray is privileged over visible light as they are incapable to reflect or refract and thus they cannot create any distraction of light for the optical viewpoints. While electron microscopes (en.wikipedia.org/wiki/Electron_microscope) are specialized in offering images of fixed objects X-ray can show images of living cells. Moreover, these microscopes are known for their highest level of sensitivity and corresponding feedback in mages.

Advantages of Polarized Light Microscopes

The advent of microscopes made scientists realize that there are so many new worlds apart from our own, small worlds of microorganisms, viruses, atoms, protons and neutrons that go unnoticed by our eyes every day. However, these microorganisms and micro particles are the fundamental elements of everything that’s there in the world today including us. Understanding these tiny particles can shed more light on our origin, existence and life itself. And the role of microscopes in helping mankind to reach new technical and medical heights is immense. Optical microscope, X-ray microscope, Scanning Acoustic microscope, Electron microscope, Neutron microscope are a few of the most used microscopes today.

Polarized Light Microscopes – Overview

Polarized light microscopes are a type of optical microscopes that involve polarized light for better understanding and visualization of materials that are anisotropic and birefringent. Polarizing microscope has a wide range of applications in the field of visual mineralogy and geology to inspect, analyze and understand tiny particles like minerals and crystals. Considering their advantages in visualizing anisotropic and birefringent particles, these microscopes are also widely used in medical and biological fields today.

Working of Polarized Light Microscopes

What differentiates these polarized light microscopes from regular laboratory microscope is the fact that they use polarized light which cannot be seen by naked eyes and which has waves vibrating in a single direction. The normal light that we see has waves that vibrate in all random directions and for analysis of materials that are anisotropic i.e. ‘direction dependent’, using the regular light microscope is impossible. To analyze these direction dependent materials that exhibit different properties in different directions, a polarizing filter has to be used to configure the direction of light waves and force them to vibrate in a single direction. Any optical microscope that uses these polarizing filters is known to be a polarized light microscope (en.wikipedia.org/wiki/Polarized_light_microscopy). A fixed polarizer known as the ‘Polarizer’ is placed between the light source and the specimen and an adjustable polarizer known as the ‘Analyzer’ is placed between the objective and the eyepiece. Both polarizer and analyzer are placed 90 degrees apart and they together help in analyzing anisotropic and birefringent particles by suppressing vibrations of natural light in random directions and polarizing them into a single direction.

Advantages of Polarized Light Microscopes

• Polarized light microscopes are the default choices for study of tiny particles in the field of visual mineralogy. Materials like crystals and fibers are anisotropic and birefringent in nature and using other high-end techniques like X-ray diffraction and scanning electron microscopy to analyze these materials wouldn’t give promising results.

• Geology, Pathology and recently even Biology, Asbestos Testing and Forensic Sciences use polarized light microscopes. In fact, in routine asbestos pathology, these polarized microscopes are mainly preferred for their high-precision and cost-effective qualities.

• Fibers, crystals and minerals are the most commonly examined materials in visual mineralogy and medical specimens like bone, teeth, striated muscle, urine crystals, gout crystals and amyloids also need polarized light microscopes to be examined. Using any other microscopes for analyzing these specimens can produce varying results.

• These microscopes are especially known for their anti-reflective and anti-scratch properties. In earth and material science applications, analysis of birefringent and anisotropic particles requires high integrity of light transmission and involves critical aspects such as internal reflections that can be only addressed by polarized light microscopes.

• These microscopes provides crucial information regarding refractive index, birefringence, sign of elongation, pleochroism, and angle of extinction of the crystals under study. No other microscope can provide information on this depth and importance in the field of crystallography.

• They have an elegant external design and advanced internal applications that are well suited for the study of crystals and minerals. The polarizer filter can be rotated and is fixed in the light path beneath the specimen and usually below the stage. The analyzer is placed 90 degrees apart from the polarizer and can be pushed in or out of the light path according to the user needs.

• They have a large circular stage with two locking brakes to deliver a smooth 360 degrees of rotation. In addition, the circular stage is stain free to avoid any optical impurity come in the way of the polarized light. Two compensator plate slots and two centering tool slots are provided in addition to prevent unwanted loss of accessories.

Scientific Laboratory Microscopes – Binocular and Trinocular

Binocular and trinocular microscopes are both compound microscope systems. They have two and three viewing eyepieces respectively. Binocular microscopes are the standard microscopes widely used in scientific laboratories across the world. Trinocular microscopes have the same technology with the only difference of the extra eyepiece that can be used for photographic viewing. Let us now discuss on these two types of laboratory microscopes in detail.

What is binocular microscope?

Binocular microscope is a microscope having two eyepieces. Most compound microscopes offer two eyepieces for viewing the images produced by a single powerful objective lens. With these microscopes the produced images for viewing are flat, 2-dimensional in character. Thus apart from the two eyepieces for viewing this compound microscope is very similar to single eyepiece compound microscopes (www.ehow.com/about_7216977_importance-compound-microscopes.html) as far as the image quality is concerned.

What is trinocular microscope?

Trinocular microscope offers three ports for viewing, respectively two for eyepieces as in binocular microscope and a third additional viewing port for microphotography or video recording of the magnified microscopic specimen. The dedicated third viewing port for camera application will allow the operator and lab technicians viewing images on a separate screen. Basically this microscope helps the operators to view the images free from the constraints of the eyepieces. With a trinocular microscope the microscopic images can be viewed more freely allowing ease of laboratory collaboration. Thanks to ease of viewing these microscopes are widely used in an array of clinical, lab and research applications.

How to use binocular and trinocular microscope?

Now let us offer below a detailed guide for using binocular microscope.

•  First fix the objective lens with the lowest power into its place. Always begin with the lowest power objective lens to view your specimen.

•  Now this is time to place the specimen on the microscope stage. Make sure that over the stage the slide is held in a clip while the specimen is in side up condition. While moving the slide always keeps an eye on the micrometer readings indicating the position of the stage.

•  Now by adjusting slowly raise the stage until you cannot raise it anymore. Make sure by watching from the side that lens does not touch slide bottom.

•  Have a look through one eyepiece and by adjusting the coarse knob continue focusing by lowering the stage from the lens. Never ever raise the stage while focusing through lens. Rather you should just do the opposite.

•  Now when you have found the specimen for sharper and clearer view adjust the focus a bit.

•  Now it is time to make the binocular eyepieces ready to ensure viewing with both eyes.  Move and adjust the eyepieces to facilitate viewing with both eyes simultaneously.

•  Now you need to adjust the focus for both eyepieces. In most binocular microscopes the right eyepiece remains fixed while the left one has telescopic capacity. You can adjust focus for both eyepieces, respectively by covering the left eye while viewing with right eye while adjusting the right knob for focusing and then doing the same with left eye while adjusting the left telescopic knob. Now you have a clear and sharp view of the specimen watchable for both eyes.

•  You can always adjust the stage forward, backward and sideways through respective knob for a better view of all areas of specimen.

•  To ensure a better and consistent lighting you need to adjust the diaphragm now. Begin by closing the diaphragm as much as possible by rotating diaphragm ring. This is done to prevent distracting light sources to a minimum.

•  Now by moving the condenser up and down gradually you can see pebble like surface. By adjusting the condenser knob further you can see it disappears offering a constant light.

•  Once you have adjusted the condenser you can open the diaphragm a little until the light provides constant illumination. Further adjusting the fine focus now you can see the sharpest possible image of the specimen.

Differences between binocular and trinocular and stereo microscope.

Binocular microscope offers a single optical path. This optical path is divided into two paths bringing the image to both of your eyes. Any microscope with two eyepieces and single optical path is a binocular microscope. For viewing the specimen, you have two separate eyepieces offering the view for both eyes and so you do not need to cover one eye while viewing the specimen as happens in microscope with singular eyepiece. Binocular microscopes with ease of viewing through both eyes offers more comfort, especially for extended viewing periods.

Trinocular microscope has also one optical path and works in the same fashion except that the optical path here is divided into three ways, respectively two for both eyes and a third for viewing port used for camera application. Apart from the third viewing port for large screen view or camera app, trinocular and stereo microscopes offers no major technical difference.

Dental Microscopes Plays a Fundamental Role for Any Dentist

A magnified view of the organ and anatomy ensures accuracy in surgery and naturally surgical microscopes in different healthcare specialties enjoy such a prominent place. For more than 6 decades the role of surgical microscopes has been a major factor in alleviating the accuracy level in all types of surgeries. Ever since the first surgical microscope was used way back in 1956, the device was further advanced to suit specifically into different surgical procedures. It has been nearly 20 years in endodontic and more than a decade in restorative dentistry that scopes with higher magnification capacity are in use.

Required level of magnification

With the dental microscope used in so called endodontic procedures the required level of magnification ranges from 2.5X magnification for accessing view to 20X magnification for exploration and surgery. Restorative dentistry requires typically a magnification ranging from 2.5X to 19X. The actual magnification range depends on various aspects like the type of microscope, components etc.

Pointless reluctance to dental microscope

In spite of this well-established truth that magnified view through dental microscopes helps in the accuracy dental diagnosis, there has been a persistent resistance among many restorative dentists against using microscopes in their patient care facility. Many restorative dentists almost regularly show their reluctance for using dental operating microscope. In spite of rising awareness over enhancing the medical procedures with state of the art magnification and other tools many dentists stick to their age-old low magnification loupes for viewing the dental condition of their patients. While this can only be characterized as a negative inertia, advanced dental care clinics would invariably use dental microscopes.

Importance of dental microscope in restorative dentistry

The wide ranging benefits of the dental microscopes for procedures pertaining to restorative dentistry are well known to medical community. In recent times, the categorical classification of tooth cracks and fractures could be done with the help of dental microscopes. Dental microscope played an invaluable role in this classification because without high magnification most dental cracks remain invisible to the low magnification loupes or naked eye. Dental surgery and restoration needs more delicate an approach because of the inaccessibility and challenging viewing condition. Naturally, for such delicate and demanding medical procedure the importance of powerful magnification remains huge.

Most restorative dentists get engaged during most of their professional practicing time in replacing the restoration provided earlier as it failed to work. Such conversion from one type of restoration to another is commonplace in restorative dentistry. Converting failing intra-coronal alloy restorations to porcelain restorations or converting composite restoration to full-coverage porcelain restorations, such conversions are the most commonplace procedures performed in any restorative dentistry clinics. Often such restorative procedure needs assessing the tooth structure properly. Without proper assessment of the tooth structure the dentist cannot accurately decide on the type of restoration needed. For example for a lasting and successful bonded porcelain or composite restoration good tooth structure can be a crucial requirement to ensure good bonding. But without high quality magnification there are chances of omission in the procedure. Naturally, dentists using advanced dental microscopes would have a better success rate with their restorative treatment.

Increasing number of dentists is finding dental microscopes invaluable

Over the past few years increasing number of dental facilities using advanced dental microscopes for surgical or restorative procedures. Obviously, this could not have been possible without the strong desire of dentists to improve their practice and success rate with the help of high magnification scopes. The surgical procedure apart dental microscopes in more ways than one revolutionized the dental diagnosis as well. From ensuring far enhanced accuracy in dental surgeries and restoration to well documented diagnosis to better treatment and quality control, use of high magnification microscopes added immense value to the dental restoration and treatment. For patients utilization of high end dental microscopes in dentist’s clinic will ensure more accuracy in the diagnostic and operative procedures.

Finally, the revolution in dentistry with dental microscopes and other high tech applications is just at its initial state and there is a fairly long way to go as far as training dentists, dental healthcare professionals and incorporation of the microscopes in the standard dental treatment and operating procedure is concerned. There is a learning curve for these instruments that needs to be managed. Nevertheless, it is a value packed investment in a dental care facility that can play a crucial role in building reputation through a greater success rate and patient satisfaction.
