Wedge Window

Optical wedge (Wedge Prism) is a wedge shaped piece of glass which refracts light rays, thus establishing a critical angle.     

 

Optical wedge (Wedge Prism) is a wedge shaped piece of glass which refracts light rays, thus establishing a critical angle. By selecting theappropriate wedge it is simple to create a precise beam deviation without affecting other beam parameters. If two wedges are used together withthe sloping surfaces in close proximity it is possible to produce a continuous variation of beam deviation by counter - rotating the wedges. Material: BK7 and Fused silica typically. Other optical materials are also available.
