Abstract: Protective lens for a laser module as well as systems that incorporate the lens. In one embodiment, a laser module system is disclosed. The laser module system includes a light-emitting diode lighting apparatus, a laser module that includes a laser-emitting aperture having a first dimension, and a protective lens that is disposed over the light-emitting diode lighting apparatus and the laser module. The protective lens includes both a smaller diameter portion that is configured to protect the laser module and a larger diameter portion that is larger in size than the smaller diameter portion and is configured to protect the light-emitting diode lighting apparatus. The smaller diameter portion is offset by an angle with respect to the larger diameter portion with the angle of offset being configured to eliminate extraneous reflections of light from the laser-emitting aperture of the laser module.
