Edmund Optics touts near-infrared linear polarizers
JULY 24, 2007 -- The extended broadband range of Edmund Optics' NIR linear polarizers makes them suitable for telecommunications applications such as fiber-optic isolators and couplers, say company representatives.
JULY 24, 2007 -- Edmund Optics, provider of optical components and tools, today announced the availability of near infra-red (NIR) linear polarizers with an extended broadband range. According to the company, these high-contrast polarizers are ideal for a variety of applications involving low-power NIR lasers, LEDs and other NIR sources. Their broadband range makes them suitable for telecommunications applications such as fiber-optic isolators and couplers.
The TECHSPEC polarizers are fabricated using a thin polymer film sandwiched between two flat pieces of B270 glass.
The polarizers provide uniform performance across a broad spectral range, achieving extinction ratios from 40 dB at 830 nm to 50 dB at 1310- and 1550 nm, says the company. The average transmission is greater than 30% for a wavelength range of 750- to 850 nm and 33% for a wavelength range of 1000- to 2000 nm.
EO's near-IR linear polarizers are available from stock in a variety of sizes for two wavelength ranges: 750- to 850 nm and 1000- to 2000 nm. Sizes range from 12.5-mm diameter to 50-mm diameter. Prices start at $215, but volume opportunities are welcomed, says the company.
