Product Description

High-Reflectivity Super Stable Cavity Spherical Mirrors for Precision Laser Systems

When precision matters, our Super Stable Cavity Reflective Spherical Mirror deliver unmatched performance for resonant cavities in fiber lasers, frequency combs, and industrial systems. Engineered with sub-nanometer surface accuracy and ultra-low thermal drift, these mirrors ensure >99.99% reflectivity even under extreme conditions. Whether you’re optimizing kW-level industrial lasers or stabilizing telecom frequency combs, our solutions balance rigorous stability with customization to meet your exact needs.

Why Choose Our Spherical Mirrors?

  • ✅ Zero Thermal Deformation: Proprietary ULE and fused silica substrates minimize alignment shifts, even at 300°C or under rapid thermal cycling, ensuring stability in high-heat environments like industrial furnaces or laser processing systems. This resistance to thermal distortion prevents performance drops, critical for maintaining precision in continuous-operation machinery.​
  • ✅ Broad Wavelength Customization: Tailor coatings for 632nm–2200nm ranges with <0.5% reflectivity deviation across the surface, 适配从可见光到近红外的多样应用。Whether in medical imaging, remote sensing, or telecommunications, this consistency ensures reliable light control without signal loss or wavelength-specific errors.​
  • ✅ Industry-Leading Precision: Achieve λ/20 surface accuracy and <5nm RMS roughness for ultra-low cavity losses, ideal for high-finesse lasers and precision spectrometers. This level of precision reduces energy waste and enhances signal clarity, making it indispensable for research-grade optical systems where data integrity is paramount.​
  • ✅ Built to Last: Validated 50,000+ hour lifespan in high-vibration, high-humidity environments, ensuring durability in harsh settings like manufacturing floors or outdoor monitoring stations. This longevity lowers maintenance costs and downtime, providing consistent performance for long-term, mission-critical operations.
