Dispersion Prisms suit laser cavities and spectrographs.

Press Release Summary:

With 30, 60, and 90° angles, Littrow Dispersion Prisms feature angular tolerance of >1 arc sec, surface quality of 10/5, surface accuracy of λ/20, and dimensional tolerances of ±.001 in. Uncoated models are suited for image dispersion because they can disperse white light into spectral components. Featuring anti-reflective coating on surface opposite 60° angle to provide constant deviation prism, coated models are suited for applications where it is critical to limit lasing to specific wavelength.

Original Press Release:

PG&O Provides Littrow Prisms for Laser Cavities & Other Optical Systems

Santa Ana, CA – Precision Glass & Optics (PG&O - www.pgo.com), global experts in optical manufacturing, precision thin film coatings, and customized optical solutions, announces a line of Littrow dispersion prisms for laser cavities and other optical systems, such as spectrographs. 

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 angleto 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-coated exit face, then back along its original path.

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 ofapplications.  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.For more information about Littrow prisms and other optics for lasers, please visit:  www.pgo.com
