Type Listed - Medical Device
Type Additional - Research Device
- Laboratory light microscopes in which light (typically
ultraviolet) that has been absorbed by the specimen and reemitted at a longer
wavelength is observed (as visible light) through the eyepiece. Appropriate
filters are used to select the correct wavelength of incoming beam to excite
the fluorescent compound and eliminate the unwanted incident wavelength from
the fluorescent light source (i.e., the specimen). Some fluorescence microscopes
can also be configured for Brightfield and/or phase-contrast observation.
These microscopes are used in histopathology and microbiology, commonly
with fluorescent dyes. The use of a vertical illuminator and dichroic mirrors
(epifluorescence) offers some advantages over fluorescence microscopy using
transmitted illumination. (UMD)
