Where to Buy Diffraction Gratings

Choose from our range of three diffraction gratings – the holographic research range, ruled research range and commercial range. Alongside our trio of ranges – available from stock or as custom-made optics – we also offer holographic diffraction grating films as customised components.

NIL Technology can design, prototype and manufacture various diffraction gratings to customers requirements. Examples include binary, blazed and slanted gratings with sub-wavelength period below 200 nm.

With a capacity to manufacture 500,000+ precision replicated optics, Optometrics, a Dynasil company, offers customers a reliable supply of diffractive, transmissive, and reflective optical components requiring high surface figure accuracy, nanometer range surface feature duplication, and low RMS surface roughness at a fraction of the original master surface production cost. Optometrics offers Echelle, filtered, holographic, infrared, ruled and transmission diffraction gratings.

Edmund Optics offers a wide range of transmission and reflection gratings for the ultraviolet (UV), visible and infrared (IR) regions. This includes both ruled and holographic gratings. We also offer polarization gratings, transmission grating beamsplitters and other variants.
