SUPERFLAT Si is a high-precision amorphous silicon layer that has been developed as a polishable coating for precision mirrors. It is characterized by an extremely low roughness (<1 nm) and enables precise shape correction and improved optical performance.

Thanks to its wide range of applications, SUPERFLAT Si is suitable for

• Mirror coatings in the aerospace industry
• Industrial class laser systems
• Optics in telescopes
• The semiconductor industry

The coating can be applied to various metals, ceramics and alloys without affecting the properties of the substrate material.
