Glan Thompson Polarizers of Calcite D12.7mm 350-2300nm with Round Mount, Code: 20703-011.
A Glan Thompson Polarizer is a polarization optic consisting of two right-angle prisms with their hypotenuse cemented together to form a rectangular element of a large length-to-width ratio. The working principle of Glan Thompson Polarizers is using the birefringent properties of the crystals to filter out the s-polarization (the ordinary ray). Glan Thompson Polarizers feature a large acceptance angle.
Shalom EO offers Stocked and Custom Glan Thompson Polarizers with high extinction ratios of 20000:1 or 20000:1, Standardized aperture sizes are accessible in stock, including:φ6mm, φ10mm, φ12.7mm, φ15mm. Other sizes are available upon request.
