Compact digital camera objective with interdigitated element alignment, stray light suppression, and anti-aliasing features |
摘要 |
There is disclosed a compact lens system having four injection-molded singlet lens elements with one of the singlet lens elements having a diffractive optical surface to control axial chromatic aberrations and another of the singlet lens elements having a flint-like plastic material to control lateral chromatic aberration. The lens system includes interdigitated flange features which provides interdigitated alignment between the lens elements. A plurality of light suppression elements are used to suppress stray light paths from reaching a detector array of the lens system. Moreover, the lens system includes an anti-aliasing surface on one of the lens elements for controlling aliasing effects.
