Superpolished Optics

In some applications such as Deep Ultra-violet (DUV) lasers, high-power lasers, ring laser gyros and femtosecond lasers, the optical components used needed to be minimal scatter to lower the loss in laser systems, these optical components must be ultra-low in surface roughness, they are called “superpolished” optics. 

Hangzhou Shalom EO offer the superpolished optical components made from substrate materials UV fused silica, BK7, sapphire, ZnSe, YAG etc. An unique processing of classical polishing is developed in Shalom EO to make the super-polished optics, <1Å roughness can be obtained, with high flatness and surface quality. The superpolished lenses, windows and mirrors and polished substrates are available.
