Abstract: A camera system for providing multispectral imaging of an object, the camera system having a longitudinal axis. The camera system comprises a quasi-collimating lens capable of receiving light from the object and separating wavelengths of the light. Each wavelength is projected to one of a plurality of intermediate image locations which are separated along the longitudinal axis. The system also comprises an achromatic imaging lens to receive the projected wavelengths of light from the quasi-collimating lens, and a pixelated detector positioned to receive the light from the achromatic imaging lens. The achromatic imaging lens and the pixelated detector are movable relative to one another in the direction of the longitudinal axis. The system is configured such that the projected wavelengths of light each form a corresponding image, the images formed on the detector when different distances within the range are achieved.
