Abstract
A color image sensor has a plurality of pixels. On the pixels zero-order diffractive color filters (DCFs) () are arranged. Different zero-order DCFs (), e.g., DCFs () transmitting red, green and blue light, respectively, are allocated to the pixels of the color image sensor. The use of DCFs () for color imaging devices brings better defined band-pass or notch filters than the presently used lacquers. The DCFs () are more stable with respect to time, temperature and any environmental aggression. The manufacture of the DCF pattern is simpler and cheaper than that of a conventional dye-filter pattern, since the different types of DCFs can be manufactured simultaneously.
