Abstract
The invention discloses a three-million-pixel mobile lens with good imaging. The three-million-pixel mobile lens comprises an image sensor and an aperture, and further comprises three aspheric lenses and one optical filter. The three aspheric lenses comprise a first lens, a second lens and a third lens, wehrien the first lens, the second lens, the third lens and the optical filter are successively arranged; the first lens and the third lens have a refractive index of 1.535 and an Abbe coefficient of 55.95; and the second lens has a refractive index of 1.585 and an Abbe coefficient of 29.91. According to the three-million-pixel mobile lens with good imaging, through improvement of a lens structure, the design has quite good imaging quality, the MTF values of a vast majority of view fields at half of a Nyquist frequency are greater than 0.5, the wavefront mean square deviation is smaller than 0.14 lambda, and the maximum distortion is -0.2%. The structure is simple, the cost is low, and the imaging effect is good.
