Description

Details

Because of cement it has higher transmission than Glan Taylor type due to reduced reflection losses at the hypotenuse interface but limited useful UV spectral range. Transmitted extraordinary beam is used. Side faces are black painted to absorb rejected ordinary beam.

Features

Broadband low power polarizers for UV, visible or near IR wavelengths
Large Acceptance Angle
High Polarization Purity
Low Power Application
RoHS Compliant
