Abstract
An infrared microscopic spectrometer includes an optical system which allows for a shifting of the optical path interactive with a sample from a sample transmissive optical path to an optical path through an ATR crystal using ATR analysis. In the shown embodiment, the shift in the optical path is in a direction perpendicular to a transmissive optical axis, at least along a portion of the shift adjacent to the transmissive optical axis. The shift is undertaken by a moving means which moves the collecting element providing the infrared rays. A sample-holding structure allows the ATR crystal to be rotated or detachably removed, as necessary.
