Abstract

The invention discloses about an aberration compensating lens, it comprises a lens bulk and a plurality of filtering film, the lens bulk is provided with a plane of light incidence, a plane of light emergent and a light axis, and the plane of light incidence and / or the plane of light emergent is made up by a plurality of discontinuous blocks, the blocks for example are a plurality of different-sized annular blocks, fan-like blocks, polygonal blocks. A plurality of filtering film are separately allocated on the blocks of the lens bulk, they comprise red band filtering film, green band filtering film or blue band filtering film.

Description

technical field [0001] The present invention relates to a lens, in particular to an aberration compensation (chromatic aberration) lens. Background technique [0002] With the advancement of modern technology, many optical products are constantly being introduced, whether it is the brightness enhancement layer of the backlight module of the display panel of the mobile phone or the display panel of the camera, the optical reading head of the CD-ROM, VCD-ROM, DVD-ROM ( Optical read head) must use the lens (lens). In addition, lenses are also indispensable in current digital still cameras (Digital Still Camera, DSC) and digital video cameras (Digital Video Camera, DVC). In the above optical products, the handling of the light source by the lens will directly affect the reliability of product operation. In general optical products, if white light is used as the light source, there will often be aberrations. [0003] Please refer to FIG. 1A , which is a schematic diagram of ab...
