<P>PROBLEM TO BE SOLVED: To provide a high-sensitive solid-state image pickup device having high utilization efficiency of incident light. <P>SOLUTION: A solid-state image pickup device has at least a condenser lens (A) for condensing incident light, a parallel conversion lens (B) for converting condensed light to parallel light and a prism (C) for spectroscopically dividing the parallel light. A plurality of photoelectric conversion elements are arranged so that the respective spectroscopic light components spectroscopically divided by (C) are incident to a plurality of the photoelectric conversion elements respectively, and (A), (B), (C) and the photoelectric conversion elements are successively constructed in close contact with one another. The surface at the light incident side of (A) has a convex curved surface at the light incident side, the interface between (A) and (B) has a concave curved surface at the light incident side, and the interface between (B) and (C) has a sloped flat plane. The refractive index of (A) is smallest among (A), (B) and (C), and the refractive index of (C) is largest among (A), (B) and (C). <P>COPYRIGHT: (C)2012,JPO&INPIT |
