Linear Polarizer, Polymer Film, 700:1, 430-670 nm, 50.8 mm

The 20LP-VIS-B Precision Linear Polarizers is constructed by laminating a polymer polarizing film between two high-precision glass windows. Each window has a high-efficiency 430 to 670 nm broadband VIS antireflection coating. The assembly is mounted in a 2 inch (50.8 mm) diameter black anodized aluminum housing for protection and provides a 30.5 mm clear aperture. The transmission axis is clearly marked. The result is a linear polarizer with high transmission and low wavefront distortion that are easy to mount.

Visible Polarizer

Our visible polarizers are recommended for 430-670 nm wavelength applications, and use a Grade A N-BK7 substrate.

Black Anodized Aluminum Housings

The polarizer assembly is mounted in a black anodized aluminum housing for protection, with the transmission axis clearly marked. The result is linear polarizers with high transmission and low wavefront distortion. The standard outer diameters are convenient for mounting into Newport rotary mounts.

Precision Linear Polarizers

Our Precision Linear Polarizers consist of dichroic sheet polymer polarizer material that is laminated between high quality glass substrates. In the visible wavelength range, these precision optics offer peak-to-valley transmitted wavefront distortion of <λ/5. They feature high extinction ratios, surface quality of 40-20 scratch-dig and offer wide angular acceptance.
