Surface Quality 40-12 Surface Irregularity λ/10@632.8nm Parallelism ＜ 30" Clear Aperture > 90% of diameter Bevel 0.2 mm x 45° Coating Protected Gold Coating: Ravg>98%@2000-12000nm Protected Gold Mirrors – Durable Broadband IR Performance
Coated with a sturdy SiO₂ dielectric film, our protected gold mirrors boast outstanding chemical stability and abrasion resistance. The overcoat retains the inherent high reflectivity of gold, and allows convenient handling and cleaning in regular lab and industrial settings.
- Average reflectivity: >96% (700 nm–2000 nm); >98% (2 μm–20 μm)
- Excellent inertness: Anti-oxidation, anti-tarnish and anti-corrosion, suitable for humid conditions
- Low scattering with stable performance across 0–45° incidence for all polarizations
- Available substrates: K9 glass, fused silica, silicon and Zerodur for superior thermal stability
Widely used for CO₂ laser routing, FTIR spectroscopy and thermal imaging, they are a reliable pick for general infrared optical systems.
Enhanced Gold Mirrors – High Peak Reflectivity for IR Lasers
Built with customized multilayer dielectric coatings, these mirrors deliver elevated reflectivity for mid-infrared light ranging from 2 μm to 20 μm.
- Peak reflectivity reaches up to 99% at designated wavelengths
- Well suited for narrowband operation and high-power lasers, especially 10.6 μm CO₂ and other MIR systems
- Custom coatings balance maximum performance at target wavelengths and decent broadband response
Featuring higher reflectance at specific infrared bands yet a narrower working spectrum, this series fits high-power laser processing, precision spectral analysis and advanced astronomical optics.
- Average reflectivity: >96% (700 nm–2000 nm); >98% (2 μm–20 μm)
