Abstract: An imaging sensor comprises: an array (108) of light-detecting elements (110), wherein each light-detecting element (110) in the array (108) of light-detecting elements (110) is arranged in the imaging sensor (106) so as to detect a respective wavelength interval, wherein the respective wavelength interval differs for different light-detecting elements; a pattern (114) arranged on the array (108) of light-detecting elements (110), wherein the pattern (114) defines a plurality of transparent areas (118), each transparent area (118) being associated with a corresponding light-detecting element (110) in the array (108) of light-detecting elements (110), wherein a size of a transparent area (118) among the plurality of transparent areas (118) is dependent of the corresponding light-detecting element (110) with which the transparent area (118) is associated.

Abstract: The present invention relates to a spectral sensor. The spectral sensor (10) comprising: a light detecting element (110); a microlens (120); and an interference filter (130) arranged between the light detecting element (110) and the microlens (120), and configured to transmit light in one or more spectral bands; wherein the microlens (120) has an effective focal length (F) exceeding a distance (D) between the microlens (120) and the light detecting element (110). The microlens (120) may be configured such that light refracted by the microlens (120), to be transmitted through the interference filter (130), converges towards a position (P) behind the light detecting element (110). The present invention further relates to an image sensor (20) comprising a plurality of spectral sensors (10).
