Request InfoPrecision Glass & Optics (PG&O)Precision Glass & Optics has released a line of Littrow dispersion prisms for laser cavities and other optical systems, suitable for applications where lasing must be limited to a specific wavelength. The prisms can be coated or uncoated and feature 30°, 60° and 90° angles. The uncoated prisms disperse white light into its spectral components, while the coated prisms feature an antireflection coating opposite the 60° angle to provide a constant deviation prism. The prisms feature angular tolerance >1 arcsec, surface quality of 10/5, surface accuracy...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2023 IssueOpal DiffusersOpal Diffusers from Precision Glass & Optics is made from opal glass for applications in which a uniform white light is needed.
