Glan Laser Crystal Polarizing Prism GLP05-UV

Glan Laser Crystal Polarizing Prism — Model GLP05-UV

Glan Laser polarizing prism, Laser-grade α-BBO, operating wavelength 220 nm-300 nm, clear aperture Ø5 mm, extinction ratio 100000:1.

Overview

LBTEK Glan Laser Crystal Polarizing Prisms separate incident light into ordinary and extraordinary rays via a high damage threshold air-spaced structure. Made from laser-grade natural Calcite or α-BBO crystals, they offer high extinction ratio (>10000:1 or >100000:1) and a wide working wavelength range (200 nm-3.0 μm depending on substrate). Anti-reflective coatings can be optionally applied at common laser lines (245 nm, 532 nm, 1064 nm, etc.). Each polarizer comes pre-installed in a non-removable, black-anodized mechanical housing with through-hole escape windows for the collection of reflected light.

Key Features
