Popis: We have evaluated wire grid polarizers for the thermal infrared in the 3 to 12μm wavelength range. Wire grid structures are an effective means of producing infrared polarizers with short optical path and having large acceptance angles. Performance of two sets of polarizers manufactured by Moxtek, for the 3-5μm and 8-12μm wavelength ranges, were tested in a Mueller matrix spectropolarimeter and found to have transmission ratios on the order of 1000.
