Using a Stereo Microscope
Using a Stereo Microscope
A stereo microscope is a kind of microscope that uses a light source to illuminate its sample or object so that the person viewing the object can see details at a sub-micron level.stereo microscope trinocular The stereo microscope was invented in 1957 by J.R. Erickson and C.W. Powell, who used a combination of techniques to produce the microscope. They combined the use of light with magnification and image stabilization to give the stereo microscope its distinctive characteristics.
The microscope is composed of a source of light and a reflector wheel which rotate about within a housing to provide illumination.stereo microscope trinocular stereo microscope trinocular The wheel provides an image of the sample or object onto a reflector plate that is illuminated by a similar source of light. This produces a reflection that the eye can then view, as well as allowing the sample or object to be viewed at various angles. It is this combination of image quality and magnification that makes the stereo microscope such a valuable scientific tool.
The two main models of stereo microscope currently available are the C.stereo microscope trinocular W. and S.M. models. The C.W. model uses a hand-held reflector wheel and a smaller stage than the S.M. model; the later model is almost the same size as a large soda bottle, making it easier to handle and more precise with magnification.
Although the C.W. and S.M. models are quite similar in features and size, there are some important differences in how they operate. In the C.W., illumination is achieved through using an internal light source. On the other hand, the S.M. model uses a lens with its own light source, so the microscopy process is completely different.
Because stereo microscopes use multiple, independent sources of light for magnification and visual inspection, they produce two images, or images of the sample and a light source that illuminates the sample. This two image produced by the microscope is referred to as the eyepiece view. It is very important that the eyepiece view be correct, because if it is not, then the image produced by the microscope is blurred and appears fuzzy. Therefore, accurate adjustments must be made in the focusing system of the stereo microscope.
In order to use the stereo microscope, certain objects must be mounted on the microscope slide. Usually, these objects are attached at one end of the slide. Many people do not realize this, but each slide is actually equipped with a holder at the bottom of the slide in which to hold the object when it is placed inside the holder. This allows for the easy inspection of samples. If you are unfamiliar with using the various controls on your stereo microscope, you may want to refer to the manual that came with your model.
