                                   WGW Wedge Windows (1, 2, 3)
       Wedge windows are laser quality windows manufactured with wedges of 1, 2, or 3. These wedges prevent interference by stray reflection, and have several applications in beam steering. When using a wedge as an output coupling mirror in a laser, usually the front surface is coated with the partial reflecting coating and the second surface with an antireflection coating.

Partial reflective coatings applied to the
first surface
AR coatings available for the second Surface
