VPH Transmission Gratings: High Efficiency & Design Flexibility
21 Apr 2022
Each Wasatch Photonics volume phase holographic (VPH) grating produced is an original, with consistent performance from one grating to the next. Our proprietary processes minimize stress, resulting in low wavefront distortion, and our stringent adherence to quality ensures minimal scatter.
By imaging the grating holographically, we retain tremendous flexibility in design as well as precise parameter control, allowing us to generate very high quality, highly custom diffraction gratings in volumes of 1 or 1000 pieces. The finished grating is sealed between two optical windows, resulting in a rugged, scratch-resistant product that can be easily handled and cleaned. Learn more about the advantages of VPH gratings
