Wedged Substrate BK7 60mm Diameter 1 Degree Wedge Angle λ/10
WSB-60C10-10-1
Wedged substrates can separate the reflected beam by the front and back surface of the substrates by the slight wedge angle. They can be used as a reference test plate for interferometers and beam samplers.
◦It can also be used as a prism to refract at a small angle. Beam deflection angle δ can be calculated refractive index n, from the wedge angle α.
δ ＝ sin−1（ n sinα） − α ≒（ n − 1） α
◦In BK7, 0.52 times the angle of the wedge, and in synthetic fused silica, 0.46 times the angle of the wedge. (Visible range, normal incidence)
