TOPvision Rhodium mouth mirrors are coated with Rhodium on the glass surface. Rhodium is a precious metal like gold and it is chemically resistant, even against acids.
However, Rhodium is far more expensive than gold. In order to alternatively offer a front surface mirror which is less expensive, we developed a unique combination of highly reflecting layers resistant even against acids, based on our longtime experience. The result is our TOPvision FS mouth mirror.
These two mouth mirrors distinguish only in one detail:
The reflexion of the Rhodium coating appears in slightly “warmer” colours, whereas the reflexion of the new combination layer appears in slightly “cooler” colours.
The high quality of TOPvision FS mirrors is shown by the same characteristics like our TOPvision Rhodium mouth mirrors.
