Infrared Optical Germanium Wedge Prism AR Coated Customized

Designed for precise light deflection and laser beam steering applications. This prism features plane inclined surfaces, effectively deflecting light towards its thicker portion. It can be used individually to deflect a beam at a specific angle, or in pairs to form an anamorphic prism assembly, which corrects the elliptical shape of a laser beam. Made from high-quality germanium and AR coated to minimize reflections and enhance performance, this customized wedge prism is ideal for a variety of advanced optical applications. Rely on our expertise for high-performance, tailored infrared optical solutions.
