High Reflectivity Film is an optical coating engineered to maximize light reflection across specific wavelengths or broadband ranges. Using advanced thin-film deposition, it achieves ultra-high reflectivity while minimizing absorption and scattering losses. Ideal for laser systems, optical resonators, and precision instruments, it ensures stable performance in harsh environments. Common applications include cavity mirrors in lasers, reflective filters in spectroscopy, and energy-efficient coatings for lighting/solar devices, balancing high reflectance with spectral selectivity.

FuZhouHigh reflectivity film is a multilayer dielectric coating (e.g., TiO₂/SiO₂) formed by periodic stacking, achieving >99.9% reflectivity in specific wavelength ranges (e.g., 1064nm laser band) via optical interference. Prepared by ion beam sputtering (IBS), it features lower absorption loss and higher laser damage threshold (>20J/cm²) than metal films, suitable for high-power laser resonators, optical filters, and fiber communication end-face reflection, serving as a core component for efficient light energy feedback in precision optical systems.
