As a specialized optical glass manufacturer since 2003, QinHuangDao LianYiDing Glass leverages 20+ years of coating expertise to deliver this precision silver mirror engineered for critical optical applications. Our ISO-certified production facility in Hebei ensures consistent quality control across all manufacturing stages, enabling us to export high-performance mirrors to global markets including North America, Europe, and Asia. This mirror achieves exceptional 99.9% reflectivity through advanced vacuum deposition technology, significantly enhancing light transmission efficiency in sensitive optical systems. With over 200 skilled technicians and 5,000-10,000 sqm factory space, we maintain rigorous standards for applications demanding uncompromising optical precision.
Core Technical Advantages:
- Ultra-High Reflectivity: 99.9% reflectivity across visible spectrum (400-700nm) minimizes light loss in optical paths
- Enhanced Durability: Multi-layer protection (copper + paint backing) prevents silver oxidation and environmental degradation
- Precision Surface: Surface accuracy of λ/10 @ 632.8nm ensures minimal wavefront distortion
- Custom Engineering: Tailored dimensions, thickness (3-25mm), and edge processing available
- Superior Flatness: < λ/2 surface flatness maintains beam collimation integrity
Technical Specifications:
| Parameter | Specification | Benefit |
| Reflective Bandwidth | 400-700nm (VIS) | Optimal for visible light instruments |
| Surface Roughness | < 5Å RMS | Reduces light scattering |
| Incidence Angle | 0-45° | Flexible optical design |
| Laser Damage Threshold | 5 J/cm² @ 1064nm | Suitable for medium-power lasers |
Critical Applications:
- Interferometry and metrology systems
- Spectrometer reference mirrors
- Laser cavity end mirrors
- Microscope illumination modules
- Astronomical telescope components
Trusted by optical engineers across 30+ countries, our mirrors undergo triple-inspection at our Tianjin/Dalian-port-shipped facility. With ISO9001:2015 quality management and ISO14000 environmental compliance, we guarantee batch-to-batch consistency for OEM instrument manufacturers. The protected silver coating outperforms standard aluminum mirrors in reflectivity by 8-10% across visible spectrum, directly translating to brighter imaging and more accurate measurements. Contact our technical team today to discuss custom specifications – our 201-300 member workforce ensures responsive service and flexible MOQs for professional optical applications.
FAQ:
Q: How is reflectivity measured?
A: We use spectrophotometry with NIST-traceable standards at 5nm intervals across specified bandwidth.
Q: Minimum order quantity?
A: Prototypes from 5pcs, production MOQ 50pcs for standard sizes.
Q: Lead time for custom sizes?
A: 15-25 days depending on coating complexity and substrate preparation.
Q: Environmental tolerance?
A: Operating range -40°C to +80°C with 85% RH max (protected coating version).
Q: Cleaning protocol?
A: Use compressed air first, then optical-grade methanol with lint-free wipes. Avoid abrasive cleaners.
Q: Packaging standards?
A: Sealed nitrogen-filled bags with custom foam inserts, crated for ocean freight.
