Abstract: TITLE: COMPACT EIGHT-LENS OPTICAL IMAGING SYSTEM The present invention relates to a compact eight-lens optical imaging system comprising a cylindrical optical barrel defining a common optical axis, an entrance pupil and eight sequentially positioned lens elements. A first spherical convex lens collects and initially converges incident light, a second aspherical lens reduces spherical aberration, a third spherical lens provides intermediate focusing, and a fourth spherical lens reduces chromatic aberration. An aperture stop disposed between the fourth and fifth lenses regulates the propagating light. The fifth lens reduces geometric distortion, the sixth lens provides field flattening, the seventh lens provides fine focusing and the eighth lens projects a corrected optical image onto an image sensor. Spacer rings maintain predetermined inter-lens spacing and retaining rings secure the lens elements within respective mounting seats. The image sensor generates electrical image data and an electronically coupled image processing unit performs residual optical-distortion correction and image-noise reduction. The optimized optical arrangement, as illustrated in FIG. 2, provides compact high-resolution imaging with controlled optical aberrations and distortion.
