Reduce Risk During The Critical Last Step
The delicate surface of a grating is incredibly fragile, with even the lightest fingerprint rendering it unusable. Don’t put your system performance at risk at the last step. Omega Optical is uniquely qualified to mount gratings into an assembly before it reaches your door.
Eliminate the risk of scrap in the process of installing gratings into your system. Handling gratings is a delicate procedure; allowing Omega to handle this phase reduces the potential of ruining the gratings you invested in.
Reduce your BOM and consolidate your vendor list by purchasing Omega’s high-quality gratings pre-assembled. We work with your team directly to design, source, and assemble gratings in their mount, taking your long list of materials to just one.
Our team will work with you directly to make sure each mount is designed to your exact specifications. Your gratings will be pre-mounted, pre-aligned, and ready to drop in. We offer special metrology for gratings.

Types of Diffractive Gratings Available as Assembled
Ruled Diffraction Gratings
Ruled diffraction gratings have a higher peak efficiency than holographic diffraction gratings and a sharper spectral response around their blaze wavelength, due to their “sawtooth” groove profile. Applications like fluorescence excitation, analytical chemistry, life sciences, telecom, physics, education and space sciences – centered around a narrow wavelength range – benefit from a ruled diffraction grating blazed at that wavelength.
Holographic Diffraction Gratings
Typical holographic diffraction gratings are produced on soda lime and fused silica glass substrates from high quality holographic master gratings and are intended for use in spectrometers and monochromators where cost and low stray light are of primary concern. They exhibit a flatter response due to their sinusoidal groove profile.
DeepUV Gratings
Omega Optical has a patent-pending deep ultraviolet transmission grating. Formerly the domain of expensive etched fused silica gratings, these economical yet high performance gratings are available for your instrumentation today.
Original/Master Gratings
Original gratings are first-run diffraction gratings where a substrate, likely glass or copper, is polished to a finish better than one-tenth of a wavelength (λ/10) with a high degree of flatness. For ruled diffraction gratings, the surface is then coated with aluminum using vacuum deposition. Photosensitive (photoresist) coating is used for holographic diffraction gratings. The master grating is completed by grooving the surface with either a ruling engine or holographic system.
Filtered Gratings
Our patented filtered diffraction gratings are a custom solution for OEM applications requiring isolation of the desired spectral band prior to diffraction, and are design limited in doing so prior to the diffraction grating component. Filtering the undesired spectral band prior to diffraction minimizes second order and ray scattering effects, maximizing spectral dynamic range.

Solution
Design & Engineering
Our commitment to finding the right solutions for difficult problems means that we are capable of doing what other engineers cannot. Some say we bend physics and solve the unsolvable. Can we? Maybe. What we know we can do is this: We ask questions and we dig, because sometimes the solutions people believe they need only scratch the surface.
Solution
Optical Coatings
Omega coating heritage dates back to 1936, and spans a wide range of technologies: Sunglasses to space-borne sun-visors; halogen light bulbs to COVID-fighting UV-C lamps, supermarket scanners to modern printers, astronomical mirrors to prestigious art installations to entertainment optics: if an application requires a precision or decorative coatings we surely have a proven solution.
Solution
Grating Manufacturing
We have the diffractive optics trifecta of multiple Ruling Engines, Holographic Mastering, and Lithographic exposure to create diffractive elements. Our in-house design and manufacturing processes provide standard or custom gratings for a range of applications, in both Original and Replicated formats.
Solution
Metrology & Quality Assurance
We believe you cannot confidently make what you cannot measure, and therefore have invested in standard and custom metrology and inspection stations. Certified ISO 9001:2015. Lean manufacturing, including 6 Sigma methodologies and approaches to problem solving.
