Gold-Coated Mirrors (Au Mirrors) | >98% Reflectivity | UV to IR Range | Laser-Grade Optical Surfaces

Uncompromising Reflectivity Demands Gold: Precision Gold-Coated Mirrors for Critical Optics

When ordinary metallic coatings fail under thermal load, humidity, or broadband applications, Manufactures delivers ultimate performance with our precision Gold-Coated Mirrors. Engineered for maximum reflectivity across ultraviolet (UV), visible, and infrared (IR) spectra, these mirrors set the standard for reliability in laser, imaging, and scientific systems where photon efficiency is non-negotiable.

Key Advantages:
✅ Ultra-High Reflectivity: Achieve >98% reflectivity across 700–20,000nm (NIR to FIR) – ideal for CO₂ lasers, FTIR, and thermal imaging.
✅ Broadband Excellence: Maintain consistent performance from UV (250nm) to far-IR – one mirror for multi-wavelength systems.
✅ Unmatched Environmental Stability: Gold’s inert nature resists oxidation, humidity, and mild chemicals, ensuring decades of reliable service.
✅ Superior Thermal Management: Withstand high-power laser irradiation (LIDT up to 5 J/cm² @ 10.6μm) without degradation.
✅ Minimal Absorption Losses: Critical for low-noise applications like astronomy and
