Product description
Monocrystalline silicon with its high heat load capacity is the preferred material choice for front-end systems.
Small grazing incident angles, in turn, generate a requirement of a 4:1 or 20:1 length-to-width ratio. As a consequence, the geometries and materials are very different from conventional optical components. Conventional polishing techniques can cause rounding on corners of rectangular-shaped optics; therefore, specialized fabrication and polishing techniques have been developed to maintain flatness across the entire rectangular surface.
We design and manufacture our synchrotron mirrors in Moorpark, California, United States.
Capabilities
As the original provider of superpolished optical components, we have been producing superpolished surfaces for over 40 years. Our proprietary process serves high volume production requirements as well as small volume, specialized applications.
Superpolished substrates feature surface roughness lower than 1 Å, scratch-dig <5-2, and inspection criteria of up to 320x magnification. The results are low scattering losses and significantly fewer defects. Substrates demonstrate an impressive λ/20 or better surface accuracy.
Our synchrotron optics and research-grade flats are supplied with polished or acid-etched diameters and bevels, adding to the level of cleanliness and durability that can be achieved.
To complement our superpolished surfaces, we offer ion beam sputtered (IBS) coatings which provide very low levels of total loss (absorption and scatter) and exceptional environmental stability.
Our custom optics have enabled scientists to achieve prize-winning results in LIGO, NASA’s Mars Curiosity Sky Crane, and in synchrotron facilities around the world.
Coatings
From high transmission broadband anti-reflection coatings to V-coats for high energy applications, our extensive coating capabilities for precision optical components deliver performance across the spectrum from the UV to the FIR.
Metrology
We have made a significant investment in metrology equipment to ensure that our customers receive quality, high-performing precision optical components.
Environmental Testing
Environmental testing of components and coatings is critical for the assurance of performance in rugged conditions. G&H environmental testing capabilities include MIL-C-675C, MIL-C-48497A, MIL-E-12397, and MIL-M-13508C for endurance against abrasion, adhesion, humidity, temperature, and environmental conditions.
