GLAN THOMPSON POLARIZER
Basic Parameters
Gran-Thompson prisms are made of various materials, including calcite crystals and a-BBO crystals.
Gran-Thompson prisms are made by bonding two crystals together. They have a very large field of view while maintaining a relatively high extinction ratio. They have a wide wavelength range; a-BBO material Gran-Thompson prisms operate in the 200-900nm wavelength range, and calcite material Gran-Thompson prisms operate in the 350-2300nm wavelength range. They are ideal wide-band, large-field polarizing devices, often used as polarizers in spectral analysis systems.
Note: Due to the presence of an adhesive layer, Gran-Thompson prisms cannot withstand high power. For high-power applications, please use our Gran laser prisms.

LiNbO3 is widely used in optical fiber communication as a birefringent crystal. The crystal has good physical and mechanical properties, wide light transmission range, high transmittance, easy processing, and lower material cost than other materials. Lithium niobate crystals are widely used in passive optical communication devices such as optical isolators, circulators, polarization splitters, polarizers, etc
POLARIZING BEAM SPLITTER（PBS）
The polarization splitter prism is plated with a multilayer film structure on the inclined surface of the right Angle prism, and then glued into a cube structure. By taking advantage of the property that the transmission rate of P-polarized light is 1 and that of S-polarized light is less than 1 when the light incident at Brewster Angle, the P polarization component can be completely penetrated after the light passes through the multilayer film structure at Brewster Angle for many times. And most of the S polarization component is reflected. Note: Specific bands and extinction ratios can be customized according to customer requirements.
