PG&O offers a wide range of coated and uncoated Littrow prisms featuring 30- 60- and 90-degree angles. Uncoated prisms are ideal for image (or light) dispersion because they can disperse white light into its spectral components. Coated Littrow prisms feature an anti-reflective coating on the surface opposite the 60-degree angle to provide a constant deviation prism. The coated prism is ideal for use in laser cavities and applications where it is critical to limit lasing to a specific wavelength. For a given wavelength, the refracted ray entering the prism travels normally to the reflectively-
Littrow prisms from PG&O feature angular tolerance >1 arc second, surface quality of 10/5, surface accuracy λ/20, and dimensional tolerances ± .001 in. PG&O also offers high performance turnkey optical solutions, including precision and commercial components for a variety of applications. All precision thin film coatings are manufactured to MIL specs, including metal and dielectric mirrors, beamsplitters, filters, antireflection coatings, neutral density filters, transparent electro-conductive coatings, and other hard and dense optical coatings needed for high performance and durability.
