Wedge Window

AOS Optics’ Wedge Windows are high-precision optical components featuring two plano surfaces with a precise included angle of 30 arc minutes, engineered for superior anti-interference performance in professional laser and optical systems. Distinguished from standard high-parallelism optical windows, their non-parallel planar structure effectively eliminates optical interference effects caused by reflected light from the front and rear surfaces. More critically, this specialized design avoids harmful optical interference feedback within laser resonators—an issue that commonly leads to poor laser output stability, mode hopping, and other performance anomalies—thus ensuring consistent, reliable operation of laser-based optical setups.

Our Wedge Windows are available in a diverse range of premium substrate materials, with flexible coating options to match distinct spectral application demands: uncoated versions for general optical use, and high-performance anti-reflection (AR) coatings covering UV, VIS, NIR, and SWIR bands for enhanced light transmittance and minimized surface reflection. Beyond our standard off-the-shelf offerings, AOS Optics provides fully customized Wedge Windows tailored precisely to your specific drawing requirements, including custom wedge angles, dimensional specifications, substrate material selections, and coating configurations.

As an indispensable optical component for high-precision laser systems, optical measurement instruments, and various professional optical setups, our Wedge Windows combine structural precision with exceptional anti-interference performance. They are a reliable choice for optimizing the stability and overall operational performance of your custom optical system designs, perfectly adapting to the rigorous demands of industrial, scientific, and research-grade optical applications.
