Wedge Windows are often used to deflect the incident light beam to a specified direction at a certain deflection angle. When used in pairs, the outgoing light beam can be positioned in any direction within an angle cone with the incident light beam as the axis through the relative rotation of the two wedges. 

The two plano surfaces of the wedge-shaped window have an angle of 30 arc minutes. The two non-parallel planes can avoid the interference effect caused by the reflected light from the front and back surfaces of the high parallelism window, and also avoid the optical interference feedback of the laser resonator, which leads to poor stability of the laser output, mode jump, etc.

AOS Optics can provide wedged windows of various materials, without coating, coated with various anti-reflection coatings (UV, VIS, NIR, and SWIR) for you to choose. We can customize wedged windows according to your drawing requirements.
