BARRINGTON, N.J., Aug. 19, 2008 – Edmund Optics Inc. has introduced IR holographic wire-grid polarizers designed to polarize light from unpolarized infrared lasers sources and ideal for attenuating light from polarized sources.
The wire-grid polarizers are manufactured using a holographic technique that creates a submicron wire grid spacing of 2700 grooves/mm. The holographic method creates finer groove spacing for short wavelength performance.
The polarizers are available in a 25-mm diameter with a clear aperture of 18 mm and a ring thickness of 5 mm, or in a 50-mm diameter with a clear aperture of 34 mm and a ring thickness of 6 mm. Substrates available are made from barium fluoride, zinc selenide, thalium bromoiodiode or geranium. They feature high transmission out to a wavelength of 30 mm, and two polarizers used together can achieve high extinction ratios of greater than 40,000:1.
They can be mounted to the company’s 25.4-mm diameter or 50-mm diameter metric polarizer mounts to create a polarizer/attenuator system where 360° rotation is required.
