Abstract
A miniature illuminator is described which is suitable for assembly into mobile electronics devices such as cell phones and computer tablets. Features of the invention overcome the complexity of current miniature illuminators by using single molded structure which includes all the electrical feedthrough connections and has the features necessary for accurate mounting of optical components. The molded structure includes laser safety connections which provide an electrical interrupt signal when the illuminator is damaged in a way that could result in propagation of non-eye safe illuminator beams. In an alternate operation the illuminator provides a signal when a subject gets too close to the illuminator and would receive unsafe VCSEL illuminator beam. The laser safety feature is integrated into the molded Illuminator package so that separate electrically connected structures to achieve this function are eliminated.
