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.
Challenges in the use of silver coatings
Despite their benefits, silver coatings present challenges to manufacturers and users, particularly due to their susceptibility to tarnishing on contact with air. To overcome this problem, a protective layer is applied to the coating to protect it from environmental influences without compromising its optical properties. The development of effective protective coatings requires advanced material science and coating technologies to achieve the desired effects. Pleiger Laser Optics utilises innovative coating processes to produce durable, high-performance silver coatings that meet the demanding requirements of modern optical applications.
Silver coatings are an indispensable component of modern optics due to their unrivalled reflective properties in the visible and IR spectral range. Their use in astronomy, laser technology and metrology emphasises their importance in many application contexts.
