Dual band night vision device

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.

1 . A night vision device, comprising:
 a multispectral objective lens;   a dichroic device structured to receive light from the multispectral objective lens and to separate light into visible/near infrared light and infrared light;   an image intensifying assembly structured to receive visible/near infrared light from the dichroic device;   an infrared camera structured to receive infrared light from the dichroic device;   at least one display structured to display an image transmitted from a device selected from the group consisting of the image intensifying assembly, the infrared camera, and a combination thereof.
