Dichroic beamsplitters longwave reflecting filters (45° AOI)

What are you looking for in Stock?

Dichroic Beamsplitters are used to separate two spectral regions which require detection at the same time. Unlike dichroic filters, these beamsplitters are designed for use at 45° and are useful for applications such as fluorescence microscopy.

The below listed dichroic beamsplitters are of the long-wave and band reflecting type and are available to purchase directly from this website in the sizes listed below. Dichroic beamsplitters can be resized at short notice for custom enquiries.

Knight Optical also offers an extensive custom optic service thanks to our many years of experience in the industry. We are able to supply dichroic beamsplitters for all key wavelengths, cut to the right size and shape for individual applications. For more information on our range of dichroic filters and beamsplitters, or to enquire about our custom service, contact our technical sales team.
