Microscopy is the science of utilizing an instrument to investigate small objects and structures. Unless helped by a microscope, microscopic means invisible to the naked sight. Currently, there are many distinct types of microscopes that are classified in numerous ways.
Professional, laboratory, fluorescence, polarizing, upright biological, binocular, metallurgical, research, inverted biological, asbestos, and other types of microscopes are used for various reasons. Dissecting microscopes are one of the most important pieces of equipment in schools, colleges, and laboratories.
The dissecting microscope, often known as the stereo or stereoscopic microscope, is a type of optical microscope. This scientific instrument is used to observe a sample at a low magnification utilizing light reflected off the object's surface rather than transmitted through it. It's a technique for creating three-dimensional graphics.
- Instead of transmitting light rays, it employs reflected light rays from the specimen surface.
- When compared to compound microscopes, it has a low magnification power.
- A dissecting microscope's magnification ranges from 5x to 80x.
- Instead of a flat image, it creates a three-dimensional image of the specimen.
- Two independent objective lenses and eyepieces are used in a dissecting microscope, resulting in two separate optical channels for each eye. As a result, a 3d picture of the specimen is created.
Principles of Dissecting Microscope
A dissecting microscope is a type of optical microscope that allows viewers to see a three-dimensional image of objects. The objective lenses and eyepieces on this microscope are separate from those on a compound light microscope. Each eye has two independent visual channels because of this. The varied angled perspectives for the left and right eye produce 3d visuals.
Instead of transmitting light, this microscope utilizes reflected light from the specimen. Opaque, thick, and solid should be the characteristics of the object to be examined using a dissecting microscope.
Most of the dissecting microscopes have two light sources: one from the upper portion of the specimen, which is reflected in the eyepieces, and the other from the lower portion of the sample, which is used to illuminate thinner materials.
Parts of Dissecting Microscope
- Light source-led illuminators are used as the primary source of light in most dissecting microscopes.
- Digital camera - a digital camera is found in most dissecting microscopes, which records or takes photographs of the specimens.
- Stereo head - the stereo head, which is movable and has two adjustable eyepieces, is positioned at the top of the stereomicroscope.
- Objective lens - it is made up of various objective lenses with various magnification capabilities.
- Specimen stage - it is put beneath the objective lens, with the specimen placed on top of it.
- Stage clips - these are where the specimen slide is kept.
- Focus knob - one focus knob on dissecting microscopes moves the head part of the microscope up and down.
- Eyepieces - two eyepieces, each with its unique magnification power, are included in a stereomicroscope.
- Diopter setting - it regulates the differences in focusing between the left and right eyes.
- The optical system - fixed-focus lensing is provided by the optical system.
What Is the Magnification Range of a Dissecting Microscope?
The overall magnification power of a dissecting microscope or stereo microscope is defined as the sum of the eyepiece and objective lens magnification powers.
An auxiliary lens is a lens that can be used to change the total magnification of a dissecting microscope. The total magnification power of a stereomicroscope will be doubled by the magnification power of an auxiliary lens.
Uses of Dissecting Microscope
- School & College Laboratories
Because it is a low-power device, students frequently use it to view the insects they have dissected for an experiment. This sort of microscope is frequently used by teachers so that pupils may examine the organs of an insect clearly. It can also be used to look into smooth, gleaming surfaces. One can view so many microscopic elements of a plant using this technology.
- Biological Applications
This scientific apparatus can be utilized for a variety of biological applications, including surgical biopsies. The majority of surgeons use stereo or stereoscopic microscopes, which provide a 3d stereoscopic image of any surgery being conducted.
- Inspection of Gemstone
Gemmologists can also use it to determine grades and view a gemstone clearly. It includes both top and bottom lighting, which helps to provide a clear view of the object put beneath the lenses. When dissecting, most individuals use the upper light, and when reading about a small object, they use both lights.
Currently, there are several providers who offer various types of lenses to customers. Schools, colleges, institutions, laboratories, and research facilities can all benefit from this equipment. To get a good microscope for their purposes, one can readily approach any of the merchants or suppliers.
So, if you're looking for reputable sellers, then you can look for multiple companies who are dealing in the microscope such as Nikon, Leica, Zeiss, Olympus, Omax, and Micron Optik – the best and trusted microscope sellers in India. With the help of these sellers, you can find out the right and adequate microscope as per your need.
So, contact them now & choose the best microscope as per your choice.
