The founders of Wasatch Photonics began producing volume phase gratings in dichromated gelatin nearly 50 years ago, and that expertise remains at the heart of what we do. We combine this experience with multiple patented designs and distinct design methodologies to optimize each grating for your unique application.
A grism is a compound optical element composed of a grating and prism(s). It is a dispersive element that permits an in-line optical layout by cleverly exploiting the differences between gratings and prisms. The prism deflects violet light more than red, while a diffraction grating deflects red more than violet. By combining the two, light can be separated into its components while canceling out the beam deviations caused by each element. Light is dispersed, but the impact to overall direction of beam travel is minimized, reducing impact on the optics of your system.
At Wasatch Photonics, we design and manufacture custom VPH grating-based grisms matched to your application needs. We can select and control the groove density and prism(s) used to create the desired dispersion and output angle(s) for your wavelength(s) of interest.
