Abstract:
1. A lens system for protection against laser light, and ballistics comprising: a first polymer lens having a convex surface and a non-zero power; two or more spectrally select filters, including a laser light filter; a second polymer lens having a concave surface; one of said filters comprising a dye disposed within one of the lenses; said filters further comprising one or more laminates selectively disposed on said convex or concave surfaces; and an adhesive for adhering the lenses together with the convex surface facing the concave surface to protectively sandwich the one or more laminates therebetween and to provide ballistics protection; wherein said second polymer lens having a non-zero power that compensates for power effects induced by the one or more laminates, so that during use the lens system has a substantially zero power.
