Abstract
The present invention is an image intensifier assembly that includes a Generation III image intensifier tube coupled to a single piece fiber optic inverter expander element. The single optical couple to the fiber optic expander element greatly enhances the overall performance parameters of the Gen III tube, as compared to traditional relay lens assemblies. The present invention image intensifier assembly can be directly substituted for a Generation II image intensifier tube assembly in a given application.
