Visible-300-700nm Beamsplitters Beam-combiners And-Dichroic Filters

Definition: Both beamsplitters and dichroic filter’s main function is to selectively transmit and/or reflect light into 2 sections inside optical systems. Beam combiners work in the opposite way they transmit and/or reflect 2 separate light beams together into one single beam.

Design and Manufacture: We design and manufacture custom beamsplitters, beam-combiners and dichroic filters across the visible range between 300 nanometres to 700 nanometres to any custom specification.

Supplying Optics: We hold an extensive inventory of stock wafer substrates, including Glass, Sapphire, Fused Silica, Calcium Fluoride, and more (perfect for plate beamsplitters and combiners) available in various thicknesses and ready for immediate coating. Post-coating, these substrates can be swiftly diced, or core drilled, significantly reducing lead times, often to less than two weeks. Additionally, we have a network of trusted optics suppliers, whom we regularly audit, to provide custom optics such as cube beam-splitters. This allows us to offer a comprehensive solution by delivering both the optics and coating as a complete package from a single supplier, simplifying your procurement process.

Coat Only Service: We also provide an express coating service for customer-supplied optics, with lead times as short as 2 weeks. If you already have the optics, we are more than happy to coat them for you. With hundreds of different-sized tooling jigs accumulated over years of manufacturing, we can often save on both tooling costs and lead times by utilising existing tooling of the same size or by making minor in-house modifications to suit your requirements.
