SphereOptics supplies VPH (volume phase holographic) transmission gratings from Wasatch Photonics. These deliver high efficiency, low polarization dependence and uniform performance over broad bandwidths and with large clear apertures – all in a robust, field-tested package. We offer multiple patented design technologies, which gives us more flexibility to recommend the best transmission grating for your unique application. We work at UV, VIS, & NIR wavelengths spanning 300-2500 nm, with bandwidths of 5-800 nm and with line frequencies of 150-5000 lines/mm.
Choose from in-stock gratings, or talk to us about designing a custom grating or grism for your next R&D project. Are you developing a new OEM product? We can optimise a transmission grating to your exact needs. As an experienced volume gratings supplier, SphereOptics and Wasatch Photonics we offer quality, performance and consistency that you can count on.
Applications for Wasatch VPH gratings and grisms include laser pulse compression, astronomy and hyperspectral imaging. The patented Dickson gratings and HD transmission gratings provide high efficiency over broad bandwidths. Therefore, they are ideal for demanding applications in optical coherence tomography (OCT), Raman & fluorescence spectroscopy, as well as in other high speed, low light level applications.
