Custom Wedge Prisms

Wedge prisms are optical components with a small angle between two optical surfaces. They are used to deviate, steer or slightly adjust the direction of a light beam. By rotating one or two wedge prisms, the beam direction can be precisely controlled.

Wedge prisms are commonly used in laser alignment, beam steering systems, optical scanning devices, rangefinders and scientific instruments.
