Patent abstract

A night vision device provides both an amplified visible light image and an infrared image, overlayed upon each other so that they appear to be a single image. A user may select to utilize either an intensified visual image only, an infrared image only, or ratios of both images simultaneously. Dichroic surfaces within the night vision device are utilized first to separate light into visible and infrared portions, and then to recombine the visible and infrared images to a single image.
