Abstract

To meet the demand for miniature camera lens, in this paper, there designed a new type of miniature plastic lens, which is made up of three lenses. The second surface of the first lens is designed as a diffractive surface. The diffractive lens is used to eliminate aberration. There has investigated the primary aberration about the systems expressed by PWC. The function relation among P_x, W_x, C_x, and the diffractive lens structure have been established. These three lens materials are ´PMMAO´, ´P-CARBO´ and ´PMMAO´. The F-number is 2. 4 and FOV is 50°. The overall length of this optical system is 6.52mm. The MTF at 250lp/mm is higher than 0. 3.
