Abstract
An apparatus is described. The apparatus includes a camera comprising a beam splitter to impose different optical paths for visible light and infra red light received by the camera. The camera also includes an infra red light detector to detect the infra red light and a visible light detector to detect the visible light, wherein, the different optical paths include an optical path having more than one internal reflection within the beam splitter.
Claims15
A method comprising:
- mounting, on a board that comprises a bottom of a camera housing, a visible light detector that is configured to detect visible light;
- mounting, on the board that comprises the bottom of the camera housing, an infrared light detector that is configured to detect infrared light;
- positioning, within a top of the camera housing, a beam splitter that (i) imposes a first optical path that has multiple internal reflections and that is for directing visible light, and (ii) imposes a second optical path that does not include any internal reflections and that is for directing infrared light;
- mounting the top of the camera housing, within which the beam splitter is positioned, on the bottom of the camera housing;
- and
- applying one or more external adjustments to the camera housing to align (i) the first optical path with the visible light detector, and (ii) the second optical path with the infrared light detector.
