Glan-type Polarizers are designed to transmit only extra-ordinary light using birefringent crystals such as Calcite, Yttrium Orthovanadate, and Beta Barium Borate from UV-IR wavelength range. Wavelength Opto-Electronics offers three types of Glan-Type Polarizers:

1. Glan-Laser

3. Glan-Thompson

Glan-Thompson, Glan-Taylor & Glan-Laser Polarizers are designed for low, medium, and high power applications respectively. Glan-Type Polarizers are applicable in situations where greater extinction ratios, greater polarization purities, and broad spectral ranges are required.
