Wedge

Wedge prism is used individually to deviate a beam through some specified angles. When used in pairs, the wedge prisms can steer a beam anywhere within a circle described by full anle 4a, where is the deviation from a single prism. The beam steering is accomplished by rotating the two wedge prisms independently of each other .
