The LBTEK Glan-Laser Crystal Polarizing Prisms are used to output linearly polarized light with high extinction ratios. LBTEK offers Glan-Laser Crystal Polarizing Prisms with the clear aperture of Ø10 mm and operating wavelengths of 350 nm-2.3 μm (anti-reflection coating 1064 nm), 200 nm-300 nm (anti-reflection coating 245 nm), 400 nm-700 nm (anti-reflection coating 532 nm), 700 nm-1100 nm (anti-reflection coating 1064 nm), and 700 nm-3.0 μm (anti-reflection coating 1064 nm). Additionally, LBTEK Glan-Laser Crystal Polarizing Prisms are pre-installed in black anodized mechanical housings that are non-detachable. The housings feature through escape windows for collecting reflected light. One end of the housing is engraved with SM1 external threads and includes a retaining ring for reverse locking and controlling the prism's polarization direction, while the other end is an optical arm. Both ends are compatible with LBTEK adjustment mounts for convenient use by customers.
