Stock & custom equilateral prisms ( uncoated & AR coated)

UVFS prisms for UV wavelength 170nm & other high index materials in VIS apps - These dispersing equilateral dispersing prisms have a very simple triangular cross section. Equilateral dispersion prisms are commonly used for wavelength separations, i.e. refracting white light into a rainbow pattern effect. Depending on the material used equilateral dispersion prisms can be used over a wide range of wavelengths. We offer UV Fused silica prisms for use in the ultra-violet wavelength from 170nm and other high index materials which are used for visible applications. Antireflective coatings are applied to most of our high index grade of equilateral dispersion prisms as high index material is sceptical to staining and corrosion which anti-reflective coatings eliminate. Antireflective coatings also help to improve output of the light as they prevent light loss due to surface reflection. The exit beam is in general at an angle to the input beam, this angle depending on the prism material, the wavelength and the incidence angle READ PDF FOR MORE INFO Materials::UV grade fused silica,F2, SF11 or equivalent Dimensions::± 0.2 mm Surface quality::<60-40 scratch/dig Coating::Antireflective Coating for visible (AV7)
