Buying Diffraction Gratings

Creating a Spectrum of Optical Solutions

See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 5423, 5520)!

Holographix works closely with our customers to assist them in the development of custom grating-based solutions from concept to production. We produce both reflection gratings and transmission gratings using our proprietary UV replication technology. Blazed, binary, sinusoidal and slanted grating profiles are available options. As part of the Headwall Group of companies, we can also produce high-volume original gratings.

The Future Depends on Optics

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.

Bringing quality into focus

Knight Optical has a range of stock diffraction gratings available, choose from our commercial, holographic and ruled research diffraction gratings for your application. If these do not meet your requirements, Knight Optical also offers custom diffraction gratings, enquire for further information.

With the combination of ultra-pure fused silica substrates, all-dielectric coatings, and a unique grating design, Gitterwerk gratings offer a very high damage threshold with maximum diffraction efficiency (up to 99.5%). Beyond that, our unique mask-based full-field exposure process eliminates any stitching artifacts or period variations in our products, resulting in a perfect beam quality with excellent homogeneity. We cover the spectrum from 250 nm – 2500 nm with a series of line densities ranging from 600 l/mm up to 3000 l/mm, which both the optical performance and the mechanical dimensions can be tailored to the customer's specific requirements.
