Ultra smooth surface window

Ultra smooth surface has a roughness less than 1nm. We can achieve a roughness of 0.1nm with the substrate of fused silica, silicon, etc.

Key features:
- Low loss
- low scatter

Applications:
- Soft X ray optical system
- Mirrors for ring laser gyroscope (RLG)
- High density wavelength division multiplexer
- High energy laser mirror
- Functional photoelectric device
- Optical window
- Polishing Magnetic Head
