Abstract
Disclosed herein is an attachment for a smartphone. The smartphone may include i) a camera with an image sensor and a focusing lens located on a back side of the smartphone for capturing an image of a target area; and ii) a white light source on the back side of the smartphone. The attachment may include a targeting optic system. When the attachment is secured to the back side of the smartphone, the targeting optic system may receive illumination emitted by the white light source and direct the illumination towards the target area from a location that is not directly in front of the camera's image sensor. The location may be farther from the focusing lens than the white light source when measured parallel to the back side of the smartphone. The attachment may also direct the illumination into the target area via the targeting optic system.
