Prisms & Beam Splitters

Prisms & Beam SplittersPrisms are used to manipulate a beam or image in an optical system. The number of polished surfaces and the angle displacement between them are system dependent. Our Prisms & Beam Splitters are used to reflect or refract light at precise angles. They are made from any optical glass such as filter glass or fused silica and can be coated to your exact specifications.

After a quote is generated by one of the Manufacturing Engineers for the particular prism or beam splitter, near net shape optical glass blanks are ordered and sent to the production line. The blank will be blocked to a tool and sent to generation, where it will be ground into a closer shape. After generation comes fine grinding, which includes grinding the prisms more precisely to reach the order's specifications. Finally, the optical prism will be polished on all desired surfaces. The prisms will either be sent out to the customer or retained in the facilities for further treatment with processes such as custom coatings and truncations. For a beam splitter, two prisms follow the outline above, are coated, matched together, then cemented.
