ABSTRACT:
An optical system for providing changes in the cross sectional dimensions of a substantially collimated monochromatic beam of light directed along an input path of the system in relation to the dimensions thereof along the output path of the system. For example, either increasing or decreasing the beam diameter of a laser source of radiant energy is representative of an area of usefulness.
