exterior focusing
1.According to the optical image theory, this paper analyzes the principle of the self-focusing lens and introduces the type and characteristics of the self-focusing lens array (SLA). The present article also discusses the calculation method of optical parameter and exterior size for the self-focusing lens and the measurement method of the image quality for the SLA. The last part of the paper analyzes and indicates the acceptable errors of the SLA of xerox machine design and assembling adjustment.
