Polyethylene-based materials are used in many infrared products, including motion detectors. However, little data exists for their infrared optical properties, except at wavelengths longer than 22 μm. The refractive indices of two such materials were measured in the 9.25 to 10.6 μm spectral range, using refraction through thin prisms.
