We present a highly miniaturized camera, mimicking the natural vision of predators, by 3D-printing different multi-
lens objectives directly onto a complementary metal-oxide semiconductor (CMOS) image sensor. Our system com-
bines four printed doublet lenses with different focal lengths (equivalent to f= 31 to 123 mm for a 35-mm film) in a
2 × 2 arrangement to achieve a full field of view of 70° with an increasing angular resolution of up to 2 cycles/deg field of view in the center of the image. The footprint of the optics on the chip is below 300m m×300m, whereastheir height is <200m. Because the four lenses are printed in one single step without the necessity for any further assembling or alignment, this approach allows for fast design iterations and can lead to a plethora of different
miniaturized multiaperture imaging systems with applcations in fields such as endoscopy, optical metrology, optical
sensing, surveillance drones, or security.
