An electronic imaging device (10) comprises a base layer (20) containing electrical functional circuitry, the base layer (20) having a first side (22) for interconnection of the circuitry and a second side (24) which serves as a photo-detection side. The second side (24) has exposed photosensitive electrical elements arranged in the base layer (20). Spacer means of a predetermined height are provided adjacent to said second side (24). This spacer means can advantageously be used for gaining control over the tolerance of a desired distance between a lens of a lens system and said photo-detection side. Thus, individual focusing of the lens system of each imager device after completion of production is no longer needed. Moreover, in one embodiment of the present invention an air gap that improves the performance of micro-lenses is formed.
