Abstract
A Fourier transform infrared (FT-IR) spectrometer based broadband infrared polarimeter has been developed around a pair of high-quality Brewster angle polarizers. These polarizers consist of four Ge plates in a chevron geometry and have been measured to have extinction ratios of less than 10-5 at four laser wavelengths from 0.63 m to 10.6 m. The polarimeter has been used to characterize wire-grid polarizers from 1 m to 12 m, as well as for full Mueller matrix determination from 1 m to 5 m using a rotating-retarder arrangement with a pair of MgF2 retarders.Citation
