1. An apparatus comprising: a first image capture sensor comprising a first image capture sensor surface; a second image capture sensor comprising a second image capture sensor surface; a prism assembly, positioned to receive light, comprising: a distal face through which the received light enters the prism assembly; a beam splitter configured to reflect a first portion of the received light, and to transmit a second portion of the received light; and a surface configured to direct the first portion of the received light onto the first image capture sensor; and a reflective unit positioned to receive the second portion of the received light and to direct the second portion of the received light to the second image capture sensor, wherein a first optical path length from the distal face to the first sensor surface is smaller than a second optical path length from the distal face to the second sensor surface, the first image capture sensor captures an image focused at a first object distance, and the second image capture sensor captures an image focused at a second object distance.
