What is a Stereomicroscope?
The stereoscopic, dissecting or stereo microscope is an optical microscopy model designed specifically for high magnification observation of a specimen, usually by using light reflecting from the object itself rather than being transmitted through it.stereo microscope diagram These instruments are often used in the preparation of photographic images and are used by medical and chemical laboratories as well as museums and other institutions to study specimens.
A stereoscopic microscope consists of two separate light sources which may be placed at either end of the microscope.stereo microscope diagram stereo microscope diagram One light source produces red light, which illuminates the sample, while the other provides a green light. The two sources are linked together by a series of mirrors, which enable the microscopes to be adjusted to either allow light to pass through the specimen or to block it from entering. In most stereomicroscopes, light rays produced by the instrument itself or by a fluorescent light source come into focus as a three dimensional image.
While many stereo microscopes are similar, some differ in that some are fixed on one side and have a slide mounted on the other; in other cases, one side is designed primarily for viewing while the other contains the slide mounted on a slide holder.stereo microscope diagram Other types of stereomicroscopes are designed so that a single light source is used for both of the specimens being examined. When the specimen being viewed is moved, the microscope moves along with it; in order to provide a clear image, it must be rotated by a specific degree each time.
A stereo microscope uses specialized lenses in order to provide a clear image. The lenses are coated with a special compound that helps to block light rays that pass through the specimen in the correct manner. In addition, the microscope's objective lenses and eyepieces must have adjustable objectives that allow the viewer to adjust the depth of view of the specimen.
There are many different types of stereo microscopes available. All but the smallest instruments are designed for microscopic observation. There are models designed for microscopy of living organisms as well as those designed solely for studying the structure and function of living tissues. For instance, there is a miniature type that is designed to observe a single grain of sand and a microscope that can be adjusted so that a microscope slide can be viewed in full colour.
It is important to note that stereo microscopes do not all contain the same degree of magnification. The magnification of any particular instrument will be based upon the number of objects to be observed and the number of lights being used. In addition, the instrument's focal length of the field will affect the magnification. of vision. If the microscope is to be used in conjunction with an instrument designed for microscopic observation, the field of vision will need to be wider than that required in a microscope used in that of a microscope designed for macroscopy, and vice versa if you need to examine a specimen that is much larger.
