Right angle prisms

There are three common uses for right-angle prisms in everyday laser applications – laser path deviations by 90° and 180°, and beam-splitting by 90° with knife-edge right-angle prisms.

Our right-angle prisms are made from UVFS or BK7 materials, with both options available uncoated or coated depending on your application. A right-angle prism can be a cost-effective solution when   there is a need to reflect light at a 90° angle. Such prisms provide an easier alignment advantage than a regular dielectric mirror, though higher input-beam losses will be noticed.

Another effective use of a right-angle prism is as a 180° reflector that allows you to turn a beam backwards with only one optical element. In all cases, the prism legs or hypotenuse can be coated with dielectric coatings to improve the performance of the optical element.
