More design technologies = a perfect fit
Volume phase holographic (VPH) gratings offer up to 40% greater efficiency than surface relief gratings, and enable more compact, transmissive designs. Our proprietary process encapsulates the grating structure between two AR coated surfaces for easy cleaning & handling. We utilize three distinct design technologies to optimize our gratings to your needs, backed by over 20 years of manufacturing experience. Learn more about VPH gratings.
HIGH DISPERSION HD GRATINGS
