As a leading manufacturer specializing in precision optical components since 2003, QinHuangDao LianYiDing Glass Co., Ltd. proudly presents our high-performance Silver Mirrors engineered for demanding laboratory equipment and scientific instruments. Operating from our 5000-10,000 sqm facility in Hebei, China, we leverage ISO-certified processes to deliver mirrors offering exceptional reflectivity and durability critical for accurate measurements and research applications. Our commitment to quality ensures these mirrors meet the stringent requirements of global laboratories across North America, Europe, and Asia.
Designed for superior optical performance, our silver mirrors provide a vital solution where maximum light throughput and minimal signal loss are paramount. Unlike standard aluminum coatings, silver offers significantly higher reflectivity across a broad visible spectrum. This makes them indispensable components in sensitive setups like spectrometers, interferometers, and laser systems where precision is non-negotiable. Trust our mirrors to enhance the accuracy and efficiency of your scientific instrumentation.
Core Advantages & Technical Specifications:
- Unmatched Reflectivity: Achieves >95% average reflectivity across the visible range (400-700nm), maximizing light utilization in critical experiments.
- Protected Durability: Features a proprietary protective overcoat safeguarding the delicate silver layer against oxidation and mild environmental factors, extending service life.
- Precision Substrates: Utilizes high-quality borosilicate glass (standard) ensuring excellent thermal stability, low expansion, and superior surface quality essential for λ/10 surface accuracy.
- Customization Ready: Available in diameters from 25mm to 300mm (standard range), with custom shapes, thicknesses, and mounting options available to integrate seamlessly into your specific instrument design.
- Reduced Scatter & Absorption: Minimizes light loss due to scatter and absorption compared to many alternatives, crucial for low-light applications and high-resolution imaging.
Typical Technical Parameters:
| Parameter | Value | Notes |
| Peak Reflectivity | >98% (approx. 600-800nm) | Highest in visible-NIR transition |
| Surface Flatness | λ/10 @ 632.8nm | Standard, higher grades optional |
| Surface Quality | 60-40 Scratch-Dig | Standard finish |
| Substrate Material | Borosilicate Glass (B270 equiv) | Fused silica, BK7 optional |
| Damage Threshold | 0.5 J/cm² (1064nm, 10ns) | Pulsed laser applications |
These mirrors directly benefit your operations by:
- Enhancing Instrument Sensitivity: Higher signal-to-noise ratios in detectors lead to more accurate data collection.
- Improving Measurement Accuracy: Superior surface flatness minimizes wavefront distortion critical in interferometry.
- Reducing Calibration Frequency: Stable, durable coating maintains performance over time.
- Offering Cost-Effective Performance: Provides superior visible reflectivity compared to many dielectric stacks at a competitive price point.
Your Assurance of Quality:
Backed by over two decades of manufacturing expertise and ISO9001/ISO14000 certified quality systems, our 201-300 strong workforce ensures consistent production standards. We understand the critical nature of components for scientific instruments exported worldwide via Tianjin, Dalian, and Qinhuangdao ports. Serving laboratories across North America, South America, Europe, and Asia, our mirrors are trusted in environments where precision is paramount. Our commitment to rigorous quality control and responsive customer support makes us a reliable partner for your optical component needs.

Frequently Asked Questions (FAQ):
Q1: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 10 pieces for common sizes and specifications. However, we offer flexibility for prototypes or specialized R&D projects – please inquire.
Q2: How durable is the protected silver coating?
A: The protective overcoat significantly enhances durability compared to bare silver. While suitable for standard laboratory environments, it is not recommended for prolonged exposure to harsh chemicals, high humidity without protection, or abrasive cleaning. Handle with care.
Q3: Can you provide mirrors with different substrate materials?
A: Yes. While borosilicate glass (B270 equivalent) is standard, we can also supply mirrors using substrates like BK7, Fused Silica (UV grade), or even specific crystal materials upon request, subject to feasibility and MOQ.
Q4: What is the lead time for standard items?
A: Lead time for standard specifications and sizes is typically 15-25 working days ex-works. Custom items may require additional time for engineering and production. Expedited options are sometimes available.
Q5: Do you provide reflectivity curves for your silver mirrors?
A: Yes. We can provide measured reflectivity data across specified wavelengths upon request for standard products. Data for custom coatings may require specific testing.
Q6: How should I clean these silver mirrors?
A: Use extreme care. Blow off loose particles with clean, dry air or nitrogen first. If necessary, use reagent-grade methanol or isopropyl alcohol and very soft, lint-free wipes (e.g., lens tissue). Apply minimal pressure. Avoid acetone or water-based cleaners. Never touch the coated surface.
Q7: Are your mirrors suitable for laser applications?
A: Our standard protected silver mirrors can handle lower power CW lasers common in labs. We provide a damage threshold specification (e.g., 0.5 J/cm² @ 1064nm, 10ns). For high-power or specific wavelength lasers, please provide details so we can advise on suitability or offer enhanced coatings.
Q8: What packaging do you use to ensure safe shipment?
A: Mirrors are individually wrapped in soft, anti-static material, securely mounted in protective foam within rigid cardboard or wooden boxes. Edges and surfaces are protected to prevent damage during transit. We prioritize safe delivery to your lab.
