A sensor, optical system, and combination lens for use with an optical sensor are disclosed. An illustrative optical system is described to include a photodetector having a proximity sensor area and an ambient light sensor area that is physically separated from the proximity sensor area as well as a combination lens that includes a proximity sensor focusing portion and an ambient light sensor focusing portion that each separately direct incident light for the proximity sensor area and the ambient light sensor area, respectively.

Combination lens including an ambient light sensor portion and a proximity sensor portion for proximity sensing and ambient light sensing

An optical sensor and optical system are disclosed. The optical sensor is disclosed to include a light source, a photodetector having a proximity sensing portion and an ambient light sensing portion, and a controller configured to implement a proximity sensing phase where the proximity sensing portion of the photodetector is utilized to obtain an incident light reading when the light source is ON and then implement an ambient light sensing phase where the ambient light sensing portion of the photodetector is utilized to obtain an incident light reading when the light source is OFF.

Matrix arrangement of photodetector for use as a proximity sensor and ambient light sensor

An optical assembly can be used in various optical devices such as optical proximity sensors, gesture sensors, or imaging sensors. The optical assembly may include a lens assembly and a light detector. The lens assembly may be configured to limit off axis rays at a central area of the light detector. The lens assembly can be a high aspect ratio lens assembly.
