Abstract :
Design of 10 mega-pixel mobile phone lens was introduced. Four plastic aspheric lenses and an IR cut-off filter are adopted. The materials of plastic aspheric lens are E48R, POLYCRA respectively. The refractive index and Abbe´s number are as followed 1.53, 58, 1.59, 29.9. ZEMAX software is adopted to optimize the design. The optimized configuration of the lenses and aberration curve are analyzed. The full field and relative aperture are 67 ° and 1/2.8 respectively. The total track length is 6.3mm. The effective focal length is 5.05mm. Back focal length is 0. 52mm.C1/2.7inch CMOS is adopted as image sensor. The MTF value of full field reached 0.1 in the spatial frequency of 340 lp/mm. The distortion is less than 2.5%.
