For Telecom Devices
BARRINGTON, N.J., Nov. 30, 2007 -- Edmund Optics has introduced new TechSpec NIR (near-infrared) linear polarizers, which it said provide an extended broadband range, making them ideally suited for a multitude of fiber-optic and low-power laser applications such as fiber-optic isolators and couplers for telecommunications.

The polarizers are available in two NIR wavelength ranges, from 750-850 nm and from 1000-2000 nm. Measuring 2.0- + 0.2-mm thick, the polarizers are offered with diameters of 12.5 mm, 25 mm, 30 mm and 50 mm in each wavelength range.

TechSpecNIRPolar.jpgThe TechSpec NIR linear polarizers feature a unique design consisting of a polymer polarization film sandwiched between two flat pieces of optical quality glass, the company said. They provide a 50-dB extinction ratio for 1310 and 1550 telecom wavelengths.

The polarizers are in stock and available for immediate delivery.

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...
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
