Fused Silica Protected Silver Metallic Mirrors Product Overview
Fused silica-substrate protected silver metallic mirrors feature a fused silica substrate and are coated with a highly reflective, dense silica protective layer. They are primarily used in the fields of spectroscopic analysis, laser systems, astronomical observation, and infrared sensing. Asin Optics is a manufacturer of protected silver metallic mirrors in China. We offer mirrors with an average reflectivity exceeding 98% across the visible to infrared spectrum. We also offer customization options for various substrates and sizes.
Why Choose Our Silver Mirrors
- Our fully reflective mirrors utilize a vacuum coating process to achieve high reflectivity across a broad spectrum ranging from visible light to infrared. Due to the superior optical properties of the silver coating, the reflective performance is insensitive to changes in the angle of incidence, maintaining a consistently high reflectivity regardless of the angle at which light strikes the surface.
- We offer two coating options: pure silver coating and silver coating with a silica protective layer. The pure silver coating provides the highest reflectivity, while the silver-silica coating protects against scratches and oxidation.
- We employ strictly controlled manufacturing processes to produce our silver-coated mirrors. Regardless of size, we can achieve a surface flatness of 1/10λ and maintain parallelism within 30 arcseconds. This surface accuracy ensures high-quality imaging and effective beam focusing.
- In addition to fused silica, we also offer BK7 optical glass and microcrystalline glass as substrate materials.
- We can provide various curvatures, including plano, concave, and convex, and can coat protective layers optimized for specific incident angles and specific wavelength bands upon request.

Enhanced Silver Coating Metallic Mirrors Applications
- Ultrafast Lasers
In picosecond and nanosecond ultrafast laser systems, the delay dispersion of mirrors must be strictly controlled; otherwise, pulse broadening will directly reduce peak power and temporal resolution. Ultrafast laser silver mirrors utilize the broadband reflective phase of the silver coating, combined with a dielectric protective layer, to achieve distortion-free pulse transmission without sacrificing reflectivity. - Infrared Spectrometers
In infrared spectrometers and various gas sensing systems, silver coatings exhibit extremely low absorption and high reflectivity across the spectrum from the visible to the far-infrared. The long-term stable reflectivity of high-reflectivity silver mirrors designed specifically for infrared applications can reduce maintenance costs. - LiDAR
Whether used for autonomous driving, atmospheric remote sensing, or topographic mapping, LiDAR optical systems require maximized transmission and reception efficiency. Custom silver mirrors for LiDAR leverage the silver coating’s excellent reflectivity and angle-insensitivity to enhance system detection range through fully customized designs.
