Wedge prisms deflect the incident beam to a specified direction at a certain deflection angle. When used in pairs, the outgoing beam can be located in any direction in a pyramid which take the incident beam as the axis through the relative rotation of the two wedge prism. The wedge angle and rear AR coating of the wedge prism can reduce the interference of the ghost image. High precision substrates can ensure the reflection and transmission wavefront error. Image Optics can provide various of wedge prism with different splitting ratio for your application.
