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.
