Due to the ion-ray process developed and optimized by us, our mouth mirrors achieve a superior reflection and layer hardness.
In our high-vacuum systems, we generate a complex layer structure at 2 x 10^-6mbar by electron ray evaporation, the reflective layer of which consists of pure rhodium. Rhodium is a precious metal like gold or platinum.

The mirror coating with rhodium on the glass surface (FS – Front Surface) has the advantage that the image is reflected directly on the surface and is therefore absolutely sharp. With a simple mirror coating on the rear side of the mirror glass, there are two reflections, one on the mirror coating and another – but weak reflection – on the surface of the glass.
