Volume Phase Holographic (VPH) Gratings

Wasatch Photonics Gratings and Diffractive Optics

The founders of Wasatch Photonics began writing Volume Phase Holographic (VPH) gratings in dichromated gelatin over 40 years ago, and no one does it better. We draw on our multiple patented design technologies to optimize each grating to its application, from stock gratings for R&D to custom gratings for our many OEMs. Our strengths include high efficiency, low polarization sensitivity, and uniform performance over broad bandwidths & large clear apertures – all in a robust, field-tested package. As an experienced volume gratings supplier, we offer quality, performance, and consistency you can count on. Learn the top 10 advantages of VPH gratings.

Our enhanced volume phase gratings are unsurpassed for use in pulse compression, astronomy, and hyperspectral imaging. Our patented Dickson gratings and HD gratings meet the needs for demanding applications in Optical Coherence Tomography (OCT), Raman & fluorescence spectroscopy, and other high speed, low light level applications.
