Abstract
A plurality of imagers, each responsive to a different wavelength range of light radiation, share the same optical system of lenses. An optical film on a substrate is used to split the light beam emanating from the shared optical system. The first wavelength range is reflected by the film to a first imager. The second wavelength range is transmitted through the film and the substrate to a second imager.
