Abstract
A second lens for a minitype combined optical system is characterized in that the second lens (G2) is a biconcave lens, the diameter (R2) of the second lens (G2) is 5+/-0.02 mm, the edge thickness (TE2) of the second lens (G2) is 1.79 mm, and the center thickness (TC2) of the second lens (G2) is 1.02+/-0.02 mm. By means of the second lens, miniaturization and high resolution are realized, imaging distortion of a minitype lens is effectively avoided, color rendition degree is high, and imaging can be achieved clearly. The minitype combined optical system can be conveniently applied to various portable digital products.
Description
Technical field
The present invention relates to optical technical field, especially a kind of micro combined optical system the second eyeglass.
