The 45Deg Polarization Beamsplitter Plate is a polarized optical element that can be used to separate the different polarization components (p and s) of the incoming light. It transmits P light and reflects s s s light, respectively.CRYLINK’s 45Deg Polarization Beamsplitter Plate is based on fused ultraviolet quartz. All product models are coated with narrow-band polarization spectroscopic film. Currently, it can support 9 wavelengths, including 405, 532, 633, 780, 808, 1030, 1064, 1310 and 1550 nm.The extinction ratio of the transmitter is greater than 10000:1 at 45 degree incidence, and the extinction ratio decreases with the change of the incident angle.CRYLINK currently offers circular (Diameter 25.4 mm) and rectangular (25 mm×36 mm) sizes. The circular splitter has a thickness of 5.0 mm, an indicator arrow on the side, an arrow direction pointing to the incident surface, and a 30 arcmin wedge angle on the exit surface to reduce reflective ghosting.The rectangular splitter is 1.0 mm thick and has no wedge angle. It is suitable for more compact light requirements and supports two-sided incoming light.CRYLINK provides 45Deg Polarization Beamsplitter Plate with excellent beam splitting performance and offers a variety of customization services, including customization of different materials, different wavelengths and different sizes of thickness. For customization requirements, please contact CRYLINK technical support.
