ABSTRACT:
Disclosed is a laser-aiming system having a means for suppressing electrical arcing and corona. The aiming system includes a light source, a member for supporting the light source having fill ports with valving mechanisms, and a buffer system for protecting the light source upon recoil of the weapon. The fill port valve connection to the member enables the evacuation of mositure and gas from within the member and further enables the introduction of dry gas or liquid for providing a stabilizing atmosphere around the light source for electrical arc suppression. The dry gas may be a dry inert gas such as nitrogen, for example, and the liquid may be ethylene glycol, for example.
