Right Angle Prisms

Right angle prisms are the most standard optical prism. Used in systems to turn images through 90 degrees. If used in cemented pairs can be used as polarizing beam splitters. With dielectric or polarizing plastic film sandwiched in the middle.

Kingsview Optical manufactures custom right angle prisms when stock lenses won’t do. From prototype batches to full production Kingsview has facility to offer both. Our specialty is offering rapid turnaround on prisms. We can also offer a number of coating options depending on your requirement.

Right angle prisms

Prism Optical Coating Options

  • Mirror Coating – Can deposit a number of different metals or dielectrics depending on your requirement

  • Wide angle broadband AR coating – When your prisms need to work over extended angles of incidence

  • Broadband Antireflective (BBAR) – Multilayer coating typical range of 425-650nm. Can be made wider and optimised to suit.

  • Polarizing coating – Can deposit polarizing coating dependent on your angle of incidence and wavelength.

  • Single layer Magnesium Fluoride (MgF2) – Standard coating works over a large range of angles of incidence

  • Edge black painted – Option of ground surfaces black painted to control stray light and protect mirror coated surfaces
