Abstract
A proximity sensor for an electronic device comprises a proximity module, a lens and an optical module secured in an air gap therebetween. The proximity module has an emitter and a detector and is configured to generate a signal that is a function of light emitted by the emitter, and light detected by the detector, some portion of the detected light having been reflected by a target external to the electronic device. A transmissive-reflective surface of the optical module is aligned with the emitter field of view (FOV) and the detector FOV. The optical module guides emitted light through a transmissive portion of the lens to the exterior of the electronic device, and guides target-reflected light collected by the transmissive portion to the detector. The emitter FOV and the detector FOV are substantially aligned with one another.
