摘要: Modified testing equipment for adjusting the back focal length of a compact camera module (CCM) is proposed. The advantages of this modified testing equipment which includes a conversion lens are that it saves on testing space, offers a smaller sized testing chart, as well as high speed chart changing, and variable object distances. The modified testing equipment can produce a test chart of 38.32 mm compared to an equivalent testing chart of 5000 mm with the conventional testing equipment. At the regular object distance of 2000 mm, both total track and testing chart size for the modified test equipment were 8.3% that of the conventional testing equipment. By using this testing equipment, the testing space can be shrunk significantly. (C) 2012 Optical Society of America
