Prisms are used to steer light, with cut and material determining how they do so. CVI Laser Optics offers a variety of prism types for bending light, reorienting images, separating wavelengths, and magnifying beams. All are offered in a range of precision-polished materials with antireflection coating options suitable for high power use in laser, scientific, and industrial applications. In addition to custom materials and dimensions, our full line of dielectric and metal coatings are available to create the ideal prism for your system.
Prisms are used in industrial applications like laser tracking & alignment, range finding, and atmospheric monitoring as often as they are employed in spectroscopy. Their broad bandwidth of operation and ability to function at high power make them a common component in laser systems, either for intracavity use in dispersion compensation or as beam separators. Our prisms achieve high laser damage threshold through precise polishing to high surface figure and quality, aided by optional low-loss antireflection coatings. All have large clear aperture, tight dimensional tolerances, and low angular deviation to ensure peak performance.
Each prism type is offered in at least two complementary materials, spanning a range of transmission wavelength, radiation resistance, and dispersion characteristics. These include N-BK7, fused silica, Suprasil 1, crystal quartz and N-F2, but other materials are available upon request. Several of our prism types have user-specified antireflection coatings available from the catalog, but any prism can be custom-coated upon request. Antireflection coatings at laser lines and bandwidths from 193 – 1550 nm are standard, with other wavelengths available upon request. In fact, most CVI Laser Optics coatings can be applied to prism surfaces, including dielectric and metal coatings, with the option of a black overcoat to prevent bleedthrough.
