50.8 mm - Visible Linear Polarizers;

These sheet polarizers are designed for 350-750 nm. Total luminous transmittance is 22% for white light; total integrated transmission for two crossed polarizers is 0.05%. The polarizing sheet is sandwiched between two optically ground and polished pieces of glass. Polarization and transmission characteristics are stable with time and prolonged visible irradiation. High intensity ultraviolet or infrared irradiation will degrade both the polarizing properties and total transmission of the unit. Recommended temperature extremes are -60°C and +80°C. Maximum survival temperature is 90°C. High relative humidity will tend to cause a separation of the glass sandwich and should be avoided.
