Wedged windows are ideal for producing minor angular or linear beam displacements and optical path differences.

Optical wedges are wedged windows used to steer the beam of light or laser. They are specifically designed to provide deviation between the first and second surface. Other uses provide transmission as wedged windows of the same power in series and in close contact it provides the beam steering. To achieve this the windows must be rotating independently.

Wedged prism windows material generally includes BK7 optical glass, borosilicates and fused silica.
