Sapphire Optics Windows, Mirrors, and Optical Flats
ZYGO is a custom optics manufacturer – all sapphire optical flats ZYGO produces are made to the most exacting standards available anywhere. We consider ourselves to be not only a window supplier, but a true design and manufacturing partner. As a worldwide leader in metrology solutions, ZYGO guarantees that we will deliver sapphire optical flats that meet or exceed your most demanding specifications.
ApplicationsSapphire's resistance to scratching and many types of chemical erosion, plus its ability to withstand pressurization and extreme temperature variations make it an excellent choice for use in military, aerospace, medical, industrial and consumer industries. Sapphire transmits over a broad wavelength region, making it a useful material for remote sensing technologies. A thin, tough sapphire optical flat can potentially replace other materials, which is of critical importance in weight-sensitive applications.
Material KnowledgeVarious material production technologies produce sapphire with different specifications such as size, thickness, and internal quality. The raw material blank's crystal orientation determines certain window characteristics. For example, a-plane sheets have historically been available in larger sizes than c-plane sapphire. However, a-plane sapphire is birefringent, while c-plane is not. ZYGO is familiar with raw material characteristics and can help select the most appropriate material for the project at hand. We have a profound understanding of how raw material properties impact manufacturing processes and overall performance.
FabricationWe have the unique ability to fabricate high-strength windows for tight transmitted wavefront and/or surface flatness, very good mid spatial frequency, very low surface roughness, and sub arc second parallelism. ZYGO employs controlled grinding and polishing processes to ensure the highest strength windows. We qualify our sapphire manufacturing processes with ring-on-ring and ASTM flexural tests.
CoatingsZYGO has years of experience designing thin film coatings for UV, VIS, MWIR, and multispectral applications. We maintain an extensive library of designs and are also experienced with coating windows requiring EMI grids.
