Linear Polarizer, Polymer Film, 1000:1, 1100-1750 nm, 25.4 mm

Laminated Polymer Film Linear Polarizers

The 10LP-NIR Precision Linear Polarizers is constructed by laminating a polymer polarizing film between two high-precision glass windows. Each window has a high-efficiency 1100 to 1750 nm broadband NIR antireflection coating. The assembly is mounted in a 1 inch (25.4 mm) diameter black anodized aluminum housing for protection and provides a 17.8 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.

Near Infrared Polarizer

Our near infrared polarizers are recommended for 1100-1750 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.
