ABSTRACT:
An apparatus includes first and second portions. The first portion has optics which cause first radiation within a selected waveband to travel along a path of travel and to have a selected field of view. The second portion introduces second radiation within the selected waveband into the field of view, without any significant degradation of a transmission efficiency of the first radiation along the path of travel. The second radiation then travels with the first radiation along the path of travel.
