For beam steering and beam shaping applications, Edmund Optics Inc. has launched its TechSpec fused silica wedge prisms, which are suitable for a variety of beam deviation options. Offering good surface characteristics with λ/10 surface accuracy and 20-10 scratch-dig, they deliver a low coefficient of thermal expansion and high transmittance for optimal performance from the ultraviolet to the near-IR. Used individually, they can deviate a laser beam by a specific angle; in pairs, they can be used in a variety of beam steering applications. Using two prisms creates an anamorphic pair to easily correct the elliptical shape of diode outputs. By rotating two wedge prisms independently of one another, pairs can be used to steer a beam anywhere in a circle.
