Abstract:
1. An infrared microscope system receiving an infrared input beam from a source of infrared radiation comprising: (a) an infrared detector; (b) microscope optics arranged to receive an infrared light beam and focus it onto a sample at a sample position and to transmit light through the sample to provide a transmitted light beam; (c) an aperture element having an aperture therein through which a beam of infrared light may be passed; (d) infrared optical elements defining a beam path for the input beam from the infrared source through the aperture to the microscope optics, and a beam path for the transmitted beam from the microscope optics through the aperture to an output beam path and thence to the detector; and (e) at least one mirror element selectively interposable in the transmitted beam path from the microscope optics to the aperture element to define when interposed a beam path from the microscope optics to the output beam path and thence to the detector that does not pass through the aperture of the aperture element.
