ABSTRACT:
An optical assembly and technique for magnified viewing which includes innal damaging laser energy protection. An objective lens subassembly is positioned on the focal axis which focuses incoming light energy over an entire field of view. An optical prism accepts the focused light energy and reorients the focused light energy which is split by a beamsplitter onto a power limiter at the intermediate focal plane so that only energy under an approximate damage threshold is allowed to pass onward. The optical assembly can provide from 4.times. to a 10.times. power magnification with up to a 60 millimeter entrance pupil diameter with internal, multi-spectral damaging laser energy protection.
