Glan-Taylor Crystal Polarizing Prism GTP10-A

Glan-Taylor Crystal Polarizing Prism — Model GTP10-A

Glan-Taylor polarizing prism, Laser-grade α-BBO, operating wavelength 300 - 700 nm, clear aperture Ø10 mm, extinction ratio 100000:1.

Overview

LBTEK Glan-Taylor Crystal Polarizing Prisms feature a high damage threshold air-spaced structure with laser-grade Calcite or α-BBO substrates. Operating wavelength covers 200 nm-3.0 μm (segmented), with extinction ratio up to >100000:1. Available with optional AR coatings at 245 nm, 532 nm, 1064 nm. Side absorber improves polarization purity. Each polarizer comes pre-installed in a non-removable, black-anodized mechanical housing. One end of the housing carries an SM1 external thread with a locking ring for counter-locking and polarization control, while the opposite end is smooth; both ends are compatible with LBTEK precision mounts.
