Embodiment Construction
[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0024] A kind of small optical lens, in the cavity of lens barrel 1, be provided with first lens 2, second lens 3, third lens 4 and fourth lens 5 and optical filter 6 successively, described first lens 2 The material of the spherical lens is LASF015 optical glass; the material of the third lens 4 is ZF17 optical glass; the material of the second lens 3 and the fourth lens 5 is F4520 optical plastic. This optical filter 6 is fixed in the cavity of lens barrel 1, and the below of optical filter 6 is exactly CCD photosensitive chip, and light enters from optical filter 6, and optical filter 6 has certain protective effect to CCD photosensitive chip, simultaneously Part of the light is also filtered to make the image bright and sharp while having good color reproduction. In addition to solving the problem of color, the filter 6 also ensures the smoo...
