An optical navigation device for a computer application includes a radiation source capable of producing a beam of radiation, a sensor for receiving an image, and an optical element for identifying movement of the feature to thereby enable a computer action to be carried out. The optical element is formed from a single piece and includes at least one frustrated total internal reflection (F-TIR) surface capable of affecting frustrated total internal reflection of the beam of radiation in the presence of the feature to thereby generate the image.

Optical input using internal reflection surfaces

A camera module lens cap is provided to protect a camera module in a mobile device where the camera module is exposed. The camera module lens cap includes an optically transparent member for positioning adjacent a camera lens, and a housing for carrying the optically transparent member. The housing includes an overhanging lip for engaging a base of the camera module.
