Optical Wedge

Wedge


wedge prism can be used to bend a laser beam to a set angle. In tandem, these prisms can serve as an anamorphic pair for correcting the elliptical shape of diode outputs or steering a beam anywhere within a circle described by the full angle 4θ, where θ is the deviation from a single prism. Beam steering, done by rotating the two prisms independently, is generally used in imaging applications to scan a beam to different locations.
