Precision grade plate beam splitters offer higher flatness and parallel specifications particularly useful in laser and imaging applications. Both faces of these precision beamsplitters are polished to a high degree of flatness of λ/4 and have excellent surface quality. Precision splitters are made from high quality optically polished BK7 with both surfaces controlled to a high degree of parallelism.

Our stock ranges of precision beamsplitters are available for use in Visible, Near Infrared and Telecoms wavelengths with 50/50 split ratio.  The beamsplitter coating is a high quality dielectric coating, the non-splitting face of the beamsplitter is multilayer antireflective coated to eliminate second face ghosting effects.

For more information on our stock range of precision beamsplitters, or to enquire about a custom quote, please contact our technical sales team.
