LBTEK-Glan-Laser Crystal Polarizers

Product Description

High Extinction Ratio: > 10 000:1, > 100 000:1
Material: Calcite, α-BBO
Wavelength Range: 200 nm-3.0 μm
Air-Spaced Design
Side-polished with Escape Windows

Constructed from two identical negative uniaxial crystal prisms (no > ne) with their optical axes aligned in parallel, LBTEK's Glan-Laser Crystal Polarizers are designed to output a linear polarization with a high extinction ratio. Featuring an air-spaced structure pre-mounted in a black anodized mechanical housing, the polarizer includes side escape windows specifically for high-power applications. When unpolarized light is incident, a high-extinction-ratio linearly polarized beam (e-ray) is obtained at the transmission end, while the reflected o-ray, along with a portion of the e-ray, is directed out through the side ports as non-pure o-light. Currently, LBTEK's Glan-Taylor Crystal Polarizers are available in two clear apertures (Ø5 mm and Ø10 mm) and four wavelength ranges (200 nm-300 nm, 300 nm-700 nm, 700 nm-3.0 μm, and 350 nm-2.3 μm). Additionally, LBTEK offers customization services for specific operating wavelengths and dimensions; please contact LBTEK Technical Support for custom requirements.

Glan Laser Crystal Polarizer, Ø5 mm

Material: Calcite/α-BBO
Clear Aperture: Ø5 mm
Operating Wavelength: 220 nm-2.3 μm (Sub-ranges available)

LBTEK's Glan-Laser Crystal Polarizers are designed to deliver high-extinction-ratio linearly polarized light. LBTEK offers these polarizers with a Ø5 mm clear aperture, covering several segmented wavelength ranges: 350 nm-2.3 μm (coated for 1064 nm), 220 nm-300 nm (coated for 245 nm), 300 nm-700 nm (coated for 532 nm), and 700 nm-1100 nm (coated for 850 nm).

Each Glan-Laser polarizer comes pre-installed in a non-removable, black-anodized mechanical housing. The housing features through-hole escape windows for the collection of reflected light. One end of the housing is engraved with an SM05 external thread with a locking ring for counter-locking and polarization control, while the opposite end is smooth. Both ends are compatible with LBTEK's precision mounts, ensuring ease of use for our customers.
