Wedge prisms are 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 angle 4α, where is the deviation from a single prism. The beam steering is accomplished by rotating the two wedge prisms independently of each other.General SpecificationsMaterial: N-BK7Design wavelength: 632.8nm, n=1.51467Dimensional tolerance: ±0.1mmSurface quality: 60-40Flatness: λ/[email protected] tolerance: ±3 arcminThickness of thin edge: 3.0mmBevel: Protective beve
