Abstract
A microscopic unit for a multi-station modular FTIR spectrometer system is disclosed. The microscope unit, which has a Cassegrain objective, not only provides the usual optical path for radiation during visual observation, and for infrared radiation in the transmission mode, but also provides a separate optical path for infrared radiation in the reflectance mode and in a macroscopic transmission mode. An optical switching wheel is in the path of entering radiation, which may enter through any of three ports; and the wheel is movable into a plurality of alternative positions, including a position in which radiation entering through one port passes through the wheel toward the objective, a position in which radiation entering through the same port is reflected by a wheel-carried mirror along the separate optical path, a position in which a wheel-carried mirror causes radiation to bypass the microscope, and positions in which other wheel-carried mirrors reflect into the microscope radiation entering through other ports.
