The world's first sputtering-based mass production of photo catalyst mirrors

What is a Photo-Catalyst?

A substance that absorbs light and so promotes a chemical reaction, without changing its own characteristics.
Various phenomena arise when a TiO2 (titanium oxide) photo catalyst absorbs ultra-violet light.

Sputtering approach is superior to the wet method in the following ways:

  • Strong film! → Long lasting characteristics
  • Uniform film thickness → Beautiful finish (managed at nanometer level)
  • Easy automation of the manufacturing process.
  • Quick equipment start-up.
  • Simplified production system.
