Silver is used in optical coatings exclusively in the visible (VIS) to infrared (IR) spectral range. This broad usability makes silver coatings a versatile tool in the optical industry. In astronomy, silver quartz mirrors are used in reflecting telescopes to collect the light of distant stars and galaxies with maximum efficiency. In laser technology, silver coatings serve as highly reflective mirrors that make complex laser systems powerful. Optical components with silver coatings are also used in measurement technology, where precision and reliability are of crucial importance, in order to improve the accuracy of measurements.

Optical coating with silver offers numerous advantages that make it attractive for a wide range of applications. The outstanding reflectivity in the visible and IR range enables efficient light guiding and collection, which significantly increases the performance of optical systems. In addition, the high reflectivity of silver improves the energy efficiency of laser systems by reducing the amount of laser light required. Applying a protective layer to silver coatings increases their resistance to tarnishing and extends the lifetime of optical components, which reduces maintenance costs and increases system reliability.
