The Rochon crystal polarizing prism can be used to output the linearly polarized light with a high extinction ratio. To meet customers' needs for different wavelength bands, LBTEK Rochon Crystal Polarizing Prisms are composed of two identical negative uniaxial crystal prisms (calcite or α-BBO) with the optical axes perpendicular to each other (both calcite and α-BBO are negative uniaxial crystals with no > ne. Calcite has excellent transmittance in the visible to near-infrared band, while α-BBO exhibits superior optical performance from ultraviolet to mid-infrared band). The prisms are bonded (for visible and infrared applications) or optically contacted (for ultraviolet applications), enabling higher power applications. When the natural light is incident, o-light emits without deflection, while e-light emits with deflection. The polarization directions of the two beams are mutually perpendicular, and the magnitude of the separation angle is related to the operating wavelength, the material, and prism wedge angle. LBTEK also offers various customization services, including special dimensions, design wavelengths, and other specifications. For specific customization needs, please contact LBTEK Technical Support.
