Product DescriptionSpecificationProduct: Silver Coated MirrorsMaterial: BK7/Fused SilicaDiameter Tolerance: +/-0.1mmThickness Tolerance: +/-0.1mmFlatness (PV): <1/10L@633nmSurface Quality: 20-10Surface Roughness: Ra<1nmAngular Deviation: <5arcsecClear Aperture: >90%Bevel: Break sharp edgesProduct DescriptionSilver Coated MirrorSilver Coated Mirror Product OverviewSilver Coating: 100–150 nm thick, offering high reflectivity.Protective Overcoat: 5–10 nm SiO2 layer to prevent oxidation.Surface Quality: λ/10 flatness at 633 nm, ensuring minimal distortion. Substrate & Coating OptionsSubstrates:BK7 Glass: Economical choice for visible light (400–700 nm), standard 2 mm thickness for 25–50 mm diameters.Fused Silica: Superior UV-Vis transparency (200–2000 nm), suitable for UV laser systems (e.g., 355 nm). Coatings:Protected Silver: >97% reflectivity from 450 nm to 20 μm, with <1% absorption loss.Enhanced Silver: Al2O3 overcoat for increased durability (50% more abrasion-resistant than SiO2). Manufacturing StandardsSilver Thickness Uniformity: ±5 nm tolerance across the aperture, verified via X-ray fluorescence (XRF).Edge Quality: Rounded edges (0.5 mm radius) to enhance handling safety and mechanical stability. These Silver Coated Mirrors appear well-suited for applications requiring high reflectivity and durability across broad spectral ranges, from visible to mid-IR, with options tailored for UV compatibility. Let me know if you'd like further analysis or comparisons with alternative mirror types. Technical SpecificationsSilver Coated Mirrors – FAQ1. How does silver coating durability compare to other metals?Protected silver coatings resist 95% RH humidity for 12+ months, while unprotected silver may tarnish within 3 months in non-controlled environments.2. Can silver coatings be used with UV light?Yes. Fused silica substrates with UV-stabilized overcoats maintain >95% reflectivity at 350–400 nm, ideal for UV curing applications.3. What is the weight of a 50 mm diameter silver-coated mirror?BK7 glass (2 mm thick): 25–30 gFused silica (3 mm thick): 35–40 gLightweight design for easy integration. 4. How to verify coating integrity upon delivery?Use a handheld spectrophotometer to measure reflectivity at 550 nm; expect ≥97%. Visible discrepancies may indicate coating defects.Related ProductsInspectionsProduction LineCompany HistoryFactory Advantages1.
