Wire-Grid Polarizers
Aug 2008
Edmund Optics Inc.Request Info
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.

Edmund.gifThe 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.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
An optical device capable of transforming unpolarized or natural light into polarized light, usually by selective transmission of polarized rays.
