Product catalog summary

Glan-Thompson Calcite Polarizers Overview
Glan-Thompson Calcite Polarizers are designed for high purity linear polarization suitable for broadband sources or multiple laser wavelengths in lower power applications. They feature a 14°-16° acceptance angle, making them ideal for use in highly converging or diverging beams. These polarizers are compatible with standard 25.4 mm holders and come with broadband antireflection (AR) coatings for visible and near-infrared (NIR) regions.
