ABSTRACT:
A multi-spectral objective lens comprising a primary lens for receiving light reflected from an object, the light including wavelengths in the SWIR and LWIR spectral bands, and optical elements spaced from the receiving means for simultaneously imaging the SWIR light in one focal plane and the LWIR light in another focal plane, thereby allowing real-time image and sensor fusion.
