Nanjing Baoyi Optics establishes quantifiable performance guarantees through parameter standardization:
1. Geometric Parameter Control
Parameter | Standard Grade | Precision Grade | Ultra-Precision Grade |
Diameter Tolerance | 0/-0.1mm | 0/-0.05mm | 0/-0.01mm |
Center Thickness | ±0.1mm | ±0.05mm | ±0.01mm |
Radius Tolerance | ±0.5% | ±0.1% | ±0.01% |
2. Optical Performance Breakthroughs· Focal Length Error: <0.1% (5x tighter than industry average)· Chromatic Aberration: <0.5% dispersion via achromatic doublet design
3. Surface Quality Grading
Parameter | Standard | High-Precision | Cutting-Edge |
Roughness (RMS) | 50Å | 20Å | 5Å |
Flatness | 1λ | λ/4 | λ/20 |
Note: λ = 632.8nm (He-Ne laser reference wavelength)
This standardization framework serves over 100 institutions including Huawei and Chinese Academy of Sciences, advancing domestic optical instruments to world-class levels.
