Wedged Substrate / WSSQ-80C12-20-1
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)

Guide | ▶An arrow mark on the thicker side of the edge indicates front surface of the substrate. ▶It is also available beam sampler (BS4) coated with anti-reflection coating on the back. WEB Reference Catalog Code/W3025 ▶It is also available fabrication of the wedged substrates with a requested coating. |

Attention | ▶Wedged substrates are not coated on both sides. There is a 3.5 to 4% reflection of the surface of the glass. ▶If the wedged substrate is inserted in the optical path of the laser beam, the transmitted beam is inclined slightly causing the refraction. |
