TOPvision FS Mirror (Pack of 12) The TOPvision FS is the alternative to the TOPvision FS Rhodium. Rhodium is even more expensive than gold. In order to offer a more favorable front surface mouth mirror, we developed a unique combination of reflection layers on the base of our decades-long experience. Both mouth mirrors distinguish only in the way of reflection. Rhodium reflects colors with a »warmer« touch, the new FS-Combi coating with a cooler touch. Specifications: 22mm, 24mm CS thread Features: Images of exact sharpness and contrast up to the smallest detail, without any distortion. Front Surface Mirror: Only one reflection, exact sharp image. Rear Surface Mirror: Two reflections, double image. Bright and brilliant reflection in natural colors thanks to an optimal reflection spectrum. High sight comfort gentle to the eye and good for fatigue-proof working. Easy cleaning due to the anti-stick effect of the special HAHNENKRATT front surface coating. Unlimited resistance against disinfection and sterilization, even against acid containing refresh liquids.
