Our superior-quality silver-metal-coated SHP front surface mirrors feature a high and broadband optical reflection of > 98% for visible light and maintain high reflectivity up to the infrared. Unlike the case with dielectric mirror optics, our optical silver coatings' reflectivity is almost independent of the incident light's polarization.
A pure silver metal layer is very soft and chemically sensitive, especially to sulfur compounds, grease, and humid atmospheres. For this reason, our SHP mirrors are protected with a dielectric layer on top of the silver coating. The protective coating improves both the mechanical robustness and the corrosion resistance of the mirrors. However, despite the protective coating, front-coated silver mirrors are generally not suitable for harsh environments*.
Thanks to their outstanding reflective properties, our SHP silver metal surface mirrors have established themselves in numerous optical measuring devices and other special applications in technical optics. Compared to aluminum mirrors, they typically offer approximately 2–5 percentage points higher reflection in the red and NIR range, making them the ideal choice for folding mirror applications or multiple deflections in optical systems.

For applications with increased mechanical stress, we have developed our SHP-D mirrors, which offer similar optical properties to our SHP silver front surface mirror but have a less sensitive mirror surface.

Handling and cleaning instructions:
Despite their protective coating, silver surfaces should not be touched with bare fingers, as this can cause them to oxidize. Proper cleaning requires non-abrasive methods to ensure that the optical quality of the mirrors is maintained in the long term. We will be happy to provide you with detailed cleaning instructions on request.
