High Tolerance N-BK7 Right Angle Prisms

TECHSPEC®  High Tolerance N-BK7 Right Angle Prisms are made from N-BK7 for use in a variety of visible light applications. Right angle prisms are used as internal reflectors to deviate light by 90° or 180° through Total Internal Reflection (TIR). TECHSPEC®  N-BK7 Right Angle Prisms can also be used in combination for image/beam displacement. TECHSPEC®  High Tolerance N-BK7 Right Angle Prisms feature low arcsecond angle tolerance compared to our N-BK7 Right Angle Prisms. These prisms are available uncoated, with specialized mirror coatings on the hypotenuse, or a combination of those mirror coating and anti-reflection coatings on the legs. These metallic mirror coatings remove the dependence on TIR and can then only be used as 90° reflectors. If you wish to use N-BK7 prisms as external mirrors, either with the incoming light reflected off the outside of the hypotenuse, or the legs, please see our High Tolerance N-BK7 Right Angle Prisms for our full selection of metallic and dielectric mirrors.
