ABSTRACT:
A light detector comprising a photo sensing chip having a light detecting surface, a cylindrical converging lens to collect incident light from different directions to a light detecting surface, at least one electrode connected to the photo sensing chip, a light detecting surface, and in a cross-sectional view along the axis Z of the light detector, one end of the lens is comprised of a central spherically curved surface having a first radius of curvature, and a peripheral spherically curved surface having a second radius of curvature. In another aspect of the invention, a flat surface is further arranged between the central spherically curved surface and the peripheral spherically curved surface. In the invention, the lens is comprised of just one lens element, and is formed by resin molding.
