CaF2 Infrared Beamsplitters

Spectral Systems is the world’s leading manufacturer of FT-IR Beamsplitter components and sub-assemblies. All of our beamsplitter coatings are designed to provide the highest performance and exceptional spectral purity. In addition, our beamsplitter products cover from the vacuum UV through the far-IR spectral region. Most of the beamsplitters we manufacture are proprietary designs for our customers. We also offer generic versions for fast integration into your design and manufacturing research and developments.

  • CaF2 Infrared Beamsplitters

    Calcium fluoride (CaF2) is the preferred material choice for Near-IR beamsplitters. Our CaF2 is of highest purity, quality and consistency and has zero O-H absorption found in all SiO2 materials. Hydroxyl band beamsplitter substrate absorption can often limit the quantitative accuracy of measurements done in the Near-IR. The bandwidth of our Photon Pro coating for CaF2 beamsplitter is optimized to cover all Near-IR and most Raman regions, both Stokes and anti-Stokes.
