WebJun 4, 1998 · We have adapted a close-cycle cryostat (T=20–300 K) to the sample compartment, which is used as a cryo chamber, of a FTIR spectrometer (frequency range 10–15 000 cm −1). A Cassegrain-type beam condenser is assembled to measure infrared absorptions of samples contained in a membrane diamond anvil cell (P up to 100 GPa). WebJan 1, 2013 · To collect FTIR spectra in transmission mode, the IR beam from the interferometer passes to the Cassegrain condenser—a two mirror optic. There, the beam is focused on a sample placed on an x, y, z motion stage and transmitted through the sample to the Cassegrain objective, and next to an adjustable aperture.
