LBTEK Glan Laser Crystal Polarizing Prisms are designed to output highly extinction-ratio linear polarized light. LBTEK offers Glan Laser Crystal Polarizing Prisms with clear apertures of Ø10 mm, working wavelengths of 350 nm – 2.3 μm (coated with 1064 nm), 200 nm – 300 nm (coated with 245 nm), 400 nm – 700 nm (coated with 532 nm), 700 nm – 1100 nm (coated with 1064 nm), and 700 nm – 3.0 μm (coated with 1064 nm).
Additionally, the LBTEK Glan Laser Crystal Polarizing Prism is pre-installed in a black anodized mechanical housing that is non-detachable. The housing features a through hole for collecting reflected light. One end of the housing has SM1 external threads with an included retaining ring, allowing reverse locking and control of the prism's polarization direction. The other end has an optical arm, which is compatible with LBTEK's adjustment frames, making it easier for customers to use.
