Parameters Optimization And Performance Measurement For Digital Camera Lens

The article discusses parameters optimization and performance measurement for CCD camera lens.The article discusses how to match between the resolution of the CCD and camera lens firstly to improve the quantity of lens possibly. It also finished the tolerance analysis of important parameters for an actual optical system with the optical design software, and modified the tolerance properly, and finally improved the rate of manufacturing. This method of tolerance analysis has a good practicability. And then, it has a detailed discussion about the design and tolerance analysis for the simple mechanism elements of lens, introduces the view of mechanism elements design and gives out the way of tolerance analysis. At last, the article discusses the measurement and analysis about the resolution, aberration and flare of the lens's performance.
