Abstract

An optical finger navigation module includes a light source configured for emitting light in a first spectrum; a cover housing disposed above the light source, the cover housing including a window plate that is configured to transmit light in at least the first spectrum, and a light guiding structure that is configured to transmit light in at least a second spectrum; a first light sensor configured to sense light in the first spectrum originally emitted by the light source, reflected by an object, and then transmitted through the window plate; a second light sensor configured to sense light in the second spectrum transmitted through the light guiding structure or the window plate; and a substrate. The light source, the cover housing, the first light sensor and the second light sensor are coupled and mounted to the substrate.
