Optical Wedge (Wedge Prism)
Optical wedge (Wedge Prism) is a wedge shaped piece of glass which refracts light rays, thus establishing a critical angle. By selecting the appropriate wedge it is simple to create a precise beam deviation without affecting other beam parameters. If two wedges are used together with the 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. Specifications: Diameter Tolerance: +0.0, -0.1mm Thickness Tolerance: ± 0.2mm Clear Aperture: >85% Wedge Tolerance: +/-3' Surface Quality: 40-20 scratch and dig Flatness: l/4 @632.8nm Protective Bevel AR coating is available by request.
