also known as stereoscopic microscopes. Its primary role is for
dissection of specimens and viewing and qualitatively
analyzing the dissected samples.
Dissection Microscope
It is used to examine
the surfaces or shapes of specimens such as viruses.
Scanning Electron Microscope (SEM)
It is used to study
the internal structure of cells through sectioned specimens.
Transmission Electron Microscope (TEM)
supports the tube and connects it to the base
arm
the flat platform where you place your slides
stage
moves the stage up and down; brings an image of the specimen into fine focus showing more clearly the detailed parts of the specimen.
fine adjustment knob
moves the tube and the low-power lens closer or farther away from the stage to view the image of the specimen.
coarse adjustment knob
provides support and serves as a stand
base
allows the viewer to look through and see the magnified image of the specimen
