Abstract

Wide-angle lenses and fish-eye lenses are broadly applied to various fields, including monitoring systems, rearview camera, event data recorders, and projectors, aiming to acquire enough visual field with the lens design on the limit sensing area of CCD. The wide-angle lenses, which apply four pieces of glass lenses with the angle of view 100 degree, the distortion controlled within 40%, and MTF in the angle of view above 40lp/mm, are proposed in this study. A piece of aspheric lens and three pieces of spherical lenses are combined for the cost-effective wide-angle lens.
