In core lens production stages, Nanjing Baoyi Optics achieves revolutionary optical performance through process innovation and comprehensive quality control:

1. Dual-Precision Grinding & Polishing· Grinding Phase:Dynamic control of pressure-time-abrasive granularity reduces surface roughness to 20Å RMS (≈2 nanometers)· Polishing Phase:Digital feedback systems boost transmittance to 99.5% while cutting scattering losses by 40%

2. Full-Lifecycle Quality TraceabilityLaser interferometers and spectrometers enable real-time monitoring of critical parameters:

• Diameter tolerance: 0/-0.01mm

• Center thickness: ±0.01mm

• Radius of curvature: ±0.01%

3. Surface Defect MinimizationManufacturing in ultra-clean environments achieves scratch/dig performance exceeding Grade A of U.S. military standard MIL-PRF-13830B.

Currently applied in aerospace remote sensing and lithography machines, our lenses maintain <0.1% defect rate.
