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.
