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.

Frequently Asked Questions

What is the difference between fused silica and K9 silver mirrors?
Fused silica has much lower thermal expansion, higher thermal stability and higher laser damage threshold, making it better for high-precision and high-power laser systems. K9 is more cost-effective for general applications.
Can these mirrors withstand high-power laser irradiation?
Yes, the fused silica substrate and protective silver coating provide a high laser damage threshold, suitable for industrial and scientific laser systems.
What is the difference between protected silver and enhanced silver coatings?
Protected silver coatings feature a single protective layer for general use, while enhanced silver coatings use multi-layer dielectric overcoats to boost reflectivity in specific wavelength ranges (e.g., NIR) and improve durability.
