Description
Fused silica silver coated reflective mirrors are high-precision optical components engineered for demanding applications in laser systems, scientific instrumentation, and aerospace optics. Constructed from a UV-grade fused silica substrate, these mirrors feature a robust protective silver reflective layer, delivering exceptional reflectivity across the visible to near-infrared (VIS-NIR) spectrum.
The ultra-low thermal expansion coefficient of fused silica ensures minimal thermal deformation, while the protective overcoating enhances durability and resistance to oxidation.
Manufactured via precision polishing and advanced thin-film deposition, these reflectors offer high surface quality, low scattering, and stable optical performance under high-power or elevated-temperature conditions. Ideal for applications requiring uncompromising precision, they are widely deployed in ultrafast lasers, interferometers, and biomedical imaging systems, where consistent performance is critical.
