Right Angle Prisms

Right Angle Prisms


Right angle can be used to deflect beams by 180° or by 90°.


Optical specifications

Right angle prisms are available in versions with standard quality or with increased precision. All edges are chamfered for protection. The surfaces are not coated. Oberflächen sind unbeschichtet.

version precision standard
flatness <λ/10 <λ/4
tolerance 90° ±5'' ±3'
tolerance 45° ±30'' ±3'
pyramidal error <30'' <3'

For both versions we offer the prisms made from N-BK7 and from fused silica.
