Abstract
An apparatus includes an image sensor partitioned into N image sensor regions. The image sensor is attached to a circuit board. A lens array having including N lenses is disposed proximate to the image sensor. Each one of the N lenses is arranged to focus a single image onto a respective one of the N image sensor regions. A spacer structure is stacked between to the lens array and the circuit board to separate the lens array from the image sensor, wherein the spacer structure surrounds a perimeter around all of the N image sensor regions and N lenses such that none of the spacer structure is disposed between any of the N lenses and N image sensor regions of the image sensor.
