ABSTRACT:
An illumination system for photomicrography includes direction of the light for illumination of the object through a fiber optic, the exit end of which replaces the usual illuminating lamp at the entrance pupil of a conventional illumination system. The light of an incandescent lamp directed through the fiber optic is used for selecting the view and focusing the camera. Light from a high intensity electronic flash, coupled to the camera shutter, is directed through the fiber optic, in replacement of the incandescent lamp, for the photography. An integrating light meter supplied by a beam splitter in the microscope tube terminates the flash when a proper exposure is achieved.
