Abstract
A multispectral wide angle refractive optical device for focusing light from a first waveband and a non-overlapping second waveband is presented. A first element formed of a first material receives incident radiation. A second element formed of diamond material receives radiation from the egress end of the first element. A third element formed of a third material receives radiation from the egress end of the second element. An optical train through the three elements onto a common focal plane is shared by the first waveband and a second waveband.
