LBTEK Wollaston Crystal Polarizing Prism is made by cementing birefringent crystals and is used to split incident light into two beams of linearly polarized light with mutually perpendicular vibration directions and spatially separated from each other, thereby outputting linearly polarized light with a high Extinction Ratio (ER). The product comes standard with a Ø10 mm Clear Aperture (CA) and offers two separation angle specifications, 15° and 20°, facilitating flexible model selection for different optical path spacings and receiving conditions. In terms of applicable wavelength bands, LBTEK provides multiple crystal materials and model versions, covering broad-spectrum requirements from deep ultraviolet to near-infrared: 350 nm-2.3 μm (calcite), 220 nm-2.3μm (α-BBO), 200-1100 nm (-UV, α-BBO), 350-700 nm (-A, α-BBO), and 700-1100 nm (-B, α-BBO). To ensure product performance, please store it in a clean and dry environment at a temperature of 20 °C ~ 30 °C and a relative humidity of ≤ 50 % RH; when not in use for a long time, it must be sealed and stored moisture-proof.
