Microspectrophotometer for crystal analysis by absorption reflectometry
A recording polarization microspectrophotometer using transmitted or reflected light was built for optical analysis of crystals with the specimen in the same position for both modes of measurements. The equipment consists of a main light source, a diffraction monochromator, a beam splitter and delay line (lens, diaphragm, vibrating biprism, V-mirror and spherical mirror, another diaphragm, another lens), a reflection transmission switching 45 deg mirror, a polarizer, a small cubic prism with specular diagonal plane for reflection spectrophotography or a large cubic prism with semitransparent diagonal plane for transmission spectrophotography with an auxiliary light beam coming from a lateral source through a diaphragm and the switching mirror, and around either prism a reference objective with mirror behind, a photocathode receiver tube, an ocular behind a rotatable analyzer and a flappable prism, and a main objective followed by a microscope stage with the specimen, then a condenser, and a switching 45 deg mirror reflecting into it light from a second auxiliary source with diaphragm and passing light to a second photocathode receiver tube.
