Gratings
Ruled Diffraction Gratings
Ruled diffraction gratings separate light into different wavelengths using evenly spaced parallel slits, creating a clear separation between wavelengths. The division of light into different wavelengths allows users to conduct spectrographic analysis that determines atomic structure. Varying diffraction grating types provide precise division, intensity, and resolution in applications ranging from lab instruments to telescopes.
For more than 40 years, OPCO Laboratory, Inc. has been a leading provider of optical design and manufacturing services for customers in the life sciences, spectroscopy, material analysis, defense, aerospace, and semiconductor industries, among many others. OPCO is committed to using the latest technology to produce state-of-the-art optics equipment.
With our cutting-edge ruling engine we produce superior-quality stock and custom-designed gratings that will meet even the most stringent requirements. We incorporate advanced metrology such as interferometers, atomic force microscopes and spectrometers into our rigorous quality assurance procedures.
We have the knowledge, skill, and equipment necessary to fulfill your optical grating requirements. As an ITAR-registered company, we produce optics that meet and exceed industry standards across the board – including ruled diffraction gratings, both reflective gratings and transmission diffraction gratings.
OPCO Laboratory, inc. offers an extensive selection of stock and custom grating products and services, including:
- Ruled diffraction gratings. We create ruled diffraction gratings using ruling engines and diamond tools to produce grooves in reflective-coated glass, polymer, or crystal substrate. Our technicians calculate the cut angles and distances with extreme precision to facilitate the desired refraction. Available in reflection or transmission.
- Echelle gratings. Echelle gratings are a unique type of blazed gratings with a tiered shape, similar to a series of steps or stairs. The groove tiers intersect at right angles and allow the diffracted light to be dispersed in a series of overlapping orders.
- Dual-blaze gratings. These gratings, also referred to as double-blazed or two-zone gratings, have two unique series of grooves on their surface. These varied groove angles allow light to be dispersed at several angles, providing a broader overall wavelength response band.
- Volume replication. We offer replication services that allow us to transfer features of optical masters into multiple surfaces for quick, efficient, accurate, and cost-effective replication. The process allows us to reproduce many precision optical components within tight tolerances and a high degree of predictability. We can recreate transmissive gratings and reflective gratings using our advanced replication capabilities without the need for slower, more traditional grinding and polishing.
