Catalog Products & Supplies General High reflectivity (HR) coating is generally required for mirrors and reflectors, though some are partial reflection or wavelength dependent. They work the opposite way to antireflection coatings. For high reflectivity, there are two main types of optical coating: metallic and dielectric coating. Aluminum, silver and gold are used for metallic coated mirrors. The performance of the coatings varies with reflectivity and wavelength range specified. An example of hybrid coating with metallic and dielectric materials is the protected or enhanced metallic coatings...

Daheng Optics Mirrors and Reflectors Across the visible spectrum, silver is the most reflective. The reflectivity of aluminum dips below 90% in the region from 0.8 to 1.0pm. In an optical system with several mirrors, this can be detrimental to performance. For example, a system with five mirrors that each has the reflectance of 85% would have a throughput of only 44%. Gold is useful only in the red and IR spectral regions. Aluminum is fairly stable as a mirror but silver tarnishes quickly unless kept in a dry and contamination-free environment. In addition, an unprotected aluminum or gold mirror...

Mirrors and Reflectors wave coating systems, which the thicknesses of the layers are generally quarter-wave. Comparing to the non-quarter-wave systems, the quarter-wave systems offer the broadest high reflection band, tens of nanometers in the visible spectrum range. High reflective coatings are affected by the incidence angle of the light. When used away from normal incidence, the reflective range shifts to shorter wavelengths, and becomes polarization dependent. This effect can be exploited to produce coatings that polarize a light beam. By manipulating the exact thickness and composition of...

Daheng Optics GCC-1010 Laser Line Dielectric HR Mirrors These laser line mirrors are designed for high reflectance with high laser damage threshold at specific laser wavelengths, suitable for laser cavities or other laser applications. Dielectric multilayer coatings are deposited on the laser grade substrates using physical vapour deposition (PVD) technologies. These coatings are extremely durable, making them resistant also to damage from repeated cleaning. 0078 China Daheng Group.
