36-657 50 mm Dia. 50:50 (R:T) CaF2 Infrared Plate Beamsplitter; t=6mm 0.8-6µm

This 50 mm diameter Calcium Fluoride (CaF2) Infrared Plate Beamsplitter, model 36-657, is a high-quality optical component sourced from Edmund Optics. It is designed for use in the infrared spectrum, specifically catering to wavelengths between 0.8 and 6µm.

The beamsplitter is a thin BS type, featuring a circular base shape and a thickness of 6mm. It is made of Calcium Fluoride, a material with the Mal-1963 Material ID, which is known for its excellent optical properties, including high transparency in the infrared region.

The beamsplitter's coating is another notable feature. The front surface is coated with EDM 36-656, a coating that enhances the beamsplitter's performance and durability.

In terms of its optical properties, the beamsplitter has a base shape of a thin lens and a reflection of 50% (0.5) and a transmission of 50% (0.5) at the beamsplitter surface. This 50:50 (R:T) ratio makes it a versatile choice for various optical applications.
