LENS AND PROCESSING METHOD OF THE SAME |
摘要 |
Disclosed is a lens wherein characteristic direction of aberration and the like can be easily determined, and a lens processing method. A reference point of the characteristic direction of aberration and the like is clarified by providing a thin portion (103) of a flange section (102) with a mark portion (106), and the characteristic direction of aberration and the like can be easily and accurately determined. Furthermore, by not removing the whole flange section (102) in the thickness direction, the center position of the lens is prevented from shifting at the time of attaching the lens (100), and the processing portion of the lens (100) can be prevented from hitting a case and the like at the time of transferring the lens (100).
