TRANSCRIPT
A Stage Micrometer is simply a microscope slide with a
finely divided scale marked on the surface. The scale is
of a known true length and is used for the calibration of
optical systems with eyepiece graticule patterns. This is
particularly important when altering between objectives
on one microscope or when using the same graticule in
different microscopes.
