Abstract
Disclosed are processes of method for making an optical sensor. The processes comprises the steps as follow: provide a carrier; mount an infrared ambient light detector, a proximity sensor and an infrared light emitter on the carrier; place a polymer layer on the carrier for fully coving the infrared ambient light detector, the proximity sensor and the infrared light emitter; provide a metal mold and press the polymer layer by metal mold for forming a first lens covering the infrared ambient light detector and the proximity sensor, a second lens coving the infrared light emitter, and a fixing concave positioned between the first and second lenses; insert and fix a light blocking element in the fixing concave for contributing to the minimization of crosstalk between the infrared ambient light detector and the infrared light emitter.
