Microscopes are scientific instruments used to see very tiny
things. There are two basic types: Stereo and Compound.
Microscopes of the stereo variety are used to observe larger things and
usually have both a top light for reflected light observations and a bottom
light for transmitted light observations. Generally they
range in powers from 10X to about 80X. Microscopes of the compound variety
are used to
look at the very tiny specimens. Generally, they have a light under the
specimen and therefore are used in transmitted light observations only.
This means that the specimen must be transparent or translucent for the image to
be anything other than a silhouette (back lit). Larger opaque specimens
will block out the light entirely and therefore should be observed with stereos. Find links below which list some of the
