N-BK7 Wedge Prisms
N-BK7 Wedge Prisms
Item Number:W-20210407A
The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism.
- Material: N-BK7, sapphire glass, quartz glass, etc.
- Dimension: 10-200mm
- Surface Accuracy: 60-40 or better
- Size Tolerance: +/-0.1mm or better
- Angle Tolerance: +/-3’or 30”
- Coating: Optional

What is wedge prism?
The wedge prism is a prism with a shallow angle between its input and output surfaces. This angle is usually 3 degrees or less. Refraction at the surfaces causes the prism to deflect light by a fixed angle. When viewing a scene through such a prism, objects will appear to be offset by an amount that varies with their distance from the prism.
VY Optoelectronics Co.,Ltd. can produce all types of glass prism lenses, the coating or painting could be available by custom orders.
Refraction of the wedge prism.
For a wedge prism in air, rays of light passing through the prism are deflected by the angle δ, which is approximately given by
where n is the index of refraction of the prism material, and α is the angle between the prism's surfaces.
Function of wedge prism
- Used Individually to Deviate a Laser Beam a Set Angle
- Combine Two to Create An Anamorphic Pair for Beam Shaping
Application of the wedge prism
- 1.Beam Steering
- 2.Tunable Lasers
