ISP Optics Infrared Beamsplitters

ISP Optics Infrared (IR) Plate Beamsplitters are available with Calcium Fluoride (CaF₂) or Zinc Selenide (ZnSe) substrates designed to provide a 50/50 beamsplitting ratio when used at 45°. The CaF₂ beamsplitters are ideal for applications in the 1.5 – 5µm or 2 – 8µm wavelength ranges. The ZnSe beamsplitters extend farther into the infrared with a 7 – 14µm beamsplitter coating and are Anti-Reflection (AR) coated on the second surface to increase throughput. ISP Optics Infrared (IR) Plate Beamsplitters are available in standard imperial sizes and are ideal for use in FTIR and Raman spectroscopy.
