Research Progress of Optical Fabriion and Surface
SiC has become the best candidate material for space mirror and optical devices due to a series of favorable physical and chemical properties. Fine surface optical quality with the surface roughness (RMS) less than 1 nm is necessary for fine optical appliion. However, various defects are present in SiC ceramics, and it is very difficult to polish SiC ceramic matrix with the 1 nm RMS.

Metallic Mirror Coatings | Edmund Optics
Silicon dioxide (SiO 2) is the generally accepted and ubiquitous choice for low-index layers, and dielectric metal oxides in general are preferred materials for UV, visible, and near-IR laser appliions. Choosing a material for high-index layers is not as straightforward: oxides of titanium, tantalum, zirconium, hafnium, scandium, and niobium
Diamond Machining: Ultraprecision Machine …
The inability to diamond machine glass results from a similar condition. The chemical reaction between the silicon content of the glass and the carbon content of the diamond creates silicon carbide, which also causes graphitization. With ferrous or glass materials, complex geometric surfaces are ground using existing machines (Figure 3).

Mirrors harness X-rays for science | symmetry magazine
2011-10-17 · The first K-B mirrors were made of glass or quartz coated with a reflective metal film. Today’s mirrors are typically made from silicon crystals polished to near-atomic smoothness and then coated with ultra-thin layers of hard silicon carbide or dense metals. The shorter the X-ray wavelength being focused, the more precise the mirror surface
