Abstract: This projection microscope comprises an elongate support member carrying a stage assembly between its ends, the stage assembly having opposed sides and an associated specimen holder. A light emitting source and a light receiving point are spaced from the stage assembly, the linear distance between them defining an optical path. An adjustable mirror assembly is carried at one end of the support member including laterally spaced first and second mirrors, the first mirror receiving light from the light emitting source and the second mirror directing light to the light receiving point. An objective lens assembly is disposed between the stage assembly and the first mirror, and a secondary lens is disposed between the second mirror and the light receiving point.
