Product DescriptionSpecificationProduct:Broadband Dielectric MirrorsMaterial:Fused Silica/BK7Clear Aperture:>90%Diameter Tolerance:+/-0.1mmBevel: Break sharp edgesFlatness (PV): <1/10L@633nmSurface Quality: 10-5Thickness Tolerance: +/-0.1mmProduct DescriptionHigh-Efficiency Broadband Dielectric Mirrors (BDMs) – Custom Optical Solutions from ChinaAs a leading manufacturer in China, we specialize in high-performance Broadband Dielectric Mirrors (BDMs) engineered for >99% reflectivity across UV to NIR spectral ranges. Our mirrors feature low dispersion and are optimized for microscopy, laser communications, and ultrafast optical systems.We offer fully customizable BDM solutions, including:Precision multilayer coatingsTailored bandwidthsRobust, application-specific designs Backed by reliable production capabilities and dedicated technical support, we deliver optical components that meet rigorous industry standards—on time and on spec.Product OverviewBroadband Dielectric Mirrors (BDMs): Key Features & ApplicationsCore FunctionHigh-efficiency reflectors (>99%) optimized for broad spectral ranges (e.g., 400–700 nm, 700–1100 nm), unlike narrowband HR mirrors.How Broadband Dielectric Mirrors (BDMs) Work?Multi-layer dielectric coatings (thin-film stacks) create constructive interference across multiple wavelengths, enabling uniform reflectivity without metallic absorption losses.AdvantagesUltra-broadband: Single mirror covers visible to NIR.Low loss: >99% reflectivity, minimal scattering/absorption.Durable: Dielectric layers resist laser damage (higher threshold than metals).Customizable: Spectral bands, AOI (0–45°), and polarization targets adjustable. Typical SpecsReflectivity: R_avg >99% (design range).Surface Quality: 10-5 scratch-dig (laser-grade).Flatness: λ/10 @ 632.8 nm for imaging.Damage Threshold: >5 J/cm2 (ns pulses, 1064 nm). ApplicationsFluorescence microscopy: Broadband excitation/emission splitting.Laser communications: Multi-wavelength signal routing.White-light interferometry: Coating uniformity metrology.OCT & LiDAR: Wide-spectrum beam steering. Design Trade-offsBandwidth vs. AOI: Performance drops at steep angles; optimize for 0–45°.Coating complexity: 20–50 layers → higher cost vs. metallic mirrors. Selection Tips1. Define range: Match mirror band to source (e.g., 400–700 nm for white-light LED).2. Check polarization: S/P split increases with AOI; specify if polarized light used.3. Verify damage threshold: Pulsed lasers need higher fluence tolerance. Next StepsNeed help specifying a Broadband Dielectric Mirrors (BDMs) for your setup?
