ABSTRACT:
A single-channel optical processing system for an energetic-beam instrument has separate sources for processing radiation and illumination radiation. The processing radiation and the illumination radiation are combined in a single optical path and directed to a sample surface inside the energetic-beam instrument through a self-focusing rod lens. The self-focusing rod lens thus has a working distance from the sample surface that will not interfere with typical arrangements of ion beams and electron beams in such instruments. A combination of polarizers and beam splitters allows separation of the combined incident radiation and the combined radiation reflected from the sample surface and returned through the same optical channel, so that the reflected radiation may be directed to an optical detector, such as a camera or spectrometer. In other embodiments, additional illumination of the sample surface is provided at an angle to the central axis of the self-focusing rod lens.
