![]() A635, Boke Mansion No. 9 Xiyuan Road Xihu District, Hangzhou 310030 China | ![]() Hangzhou Shalom EO offers superpolished optical components with ultra-low surface roughness made of substrate materials including UV fused silica, BK7, sapphire, Zerodur, ZnSe, ZnS, germanium, silicon, CaF2, MgF2, YAG and others, in the forms of lenses, windows, mirrors, mirrors for ring laser gyros, and superpolished substrates. Shalom EO developed an efficient and reliable super-polishing technique through modification the classical super-polishing methods. Inspections are carried using Bruker Atom Force Microscopes and Zygo interferometer, where we implement strict control of qualities. Shalom EO is capable of obtaining super polished optics of <1 Å roughness, 0/0 scratch/dig in the central area, together with high flatness, minimized scattering loss, and absorption. our superpolish optics are suitable for applications ranging from DUV lasers, high power lasers to laser gyro systems. Custom dimensions and optional High Reflection (HR) coatings or Anti-Reflection (AR) coatings are available. |
![]() The Future Depends on Optics Edmund Optics101 East Gloucester Pike Barrington, NJ 08007 United States | ![]() Edmund Optics offers superpolished laser window substrates where both surfaces have <1 Å r.m.s. surface roughness. The low scatter surfaces are ideal for UV and high power laser applications. We use UV fused-silica substrates with polished bevels and edges. Our in-house manufacturing enables custom versions with dimensions from 6 mm to 76.2 mm and different shapes; the surface roughness can be even <0.5 Å. |
