Abstract

Polaroid HN22, a popular sheet polarizer, has been measured to be a nearly half wave retarder in the 3.6 to 5.4 μ m spectral band with a transmittance of approximately 20%. The exact retardance value may be tuned to the range of 60° - 260° by tilting the HN22 with respect to the incident beam. The material's polarizing effects have been shown to be minimal in this waveband. Its availability, relatively large available aperture, large field of view, and low cost make HN22 an excellent candidate for use as an infrared retarder for systems operating from 3.6 to 5.4 μ m. As such, HN22 may be used for rotating the plane of polarization of an incident linearly polarized beam as well as to convert between circular polarization states.
