Volume Phase Holographic (VPH) Gratings

The founder of Wasatch Photonics began working on volume phase holographic gratings (VPH) forty years ago and is an absolute leader in this field. We have multiple patented design technologies to optimize each grating for various applications, from spot gratings used for R&D to OEM customized gratings. Our advantages include high efficiency, low polarization sensitivity, consistent performance over a wide bandwidth, and a large aperture - all in a robust and tested package.

Enhanced version of volume phase holographic grating for use inPulse compression, astronomy, hyperspectral imagingThere is an absolute advantage in strength. Dickson gratings and HD gratings with patented technology can meet various applications in applied optics, such asOptical correlation tomography（OCT）Raman spectroscopy, fluorescence spectroscopy, and other high-speed, low light level applications.
