Abstract
Techniques for shielding an optical sensor are described. An example of an electronic device includes an optical sensor and a combined light-focusing and electrical-shielding unit disposed over the optical sensor. The light-focusing and electrical-shielding unit has two portions. The first portion gathers light and focuses the light on the electrical sensor. The second portion encloses sides of the first portion and is coated with an electrically conductive material to shield the optical sensor from electromagnetic interference.
