BK7/UV fused silica/Sapphire glass wedge window

Wedge prisms can be applied singularly, to deviate a laser beam a specified angle,or with an additional wedge prism for laser beam steering applications

• When making use of one single wedge prism the incident beam of light is refracted at a particular deviation angle. Rotating the wedge causes the deviated beam trace to specify out a circle with an angle equivalent to two times the original deviation angle.
•  While using a pair of wedge prisms - due to the fact that every prism is able to trace out a circle of two times the deviation angle, the complete deviation by two prisms is 4 times the deviation angle.
•  By controlling the angle of every prism individually, the beam can be positioned at just about any position within the circle. This often is used for scanning with a beam different areas in imaging applications. Additionally, 2 wedge prisms enable to fix an elliptical figure of a diode output (anamorphic pair for beam shaping).

N-BK7 Wedge Prisms are best for laser beam steering applications and are offered in 2°to 10°.Moreover, they can be quoted uncoated as well as coated with any of three standard AR coatings below
