Abstract
An optical navigation device includes an optical transmission element, operable in use to transmit light from an illumination source to a sensor via a mousing surface, and a housing unit. The optical transmission element may have an alignment shaft. Ideally the optical transmission element and housing unit are assembled to a substrate by snap-fit. The alignment shaft ensures that the optics are properly aligned to the substrate and the light source and sensor thereon.
