Abstract:
An apparatus and method for protecting at least one component of a light source are provided. The apparatus includes a shield for the component, with this shield having a plurality of locations that are substantially transparent to an emission wave length of the light source. The shield is positioned such that during use of the light source, one of the substantially transparent locations of the shield is disposed between the at least one component of the light source and an object that is to be irradiated. The apparatus also includes a mechanism for advancing the shield upon activation of the light source or an element thereof in order to be able to dispose a different one of the substantially transparent locations of the shield between the at least one component of the light source and an object that is to be irradiated.
