Abstract
Correction is provided for a curved or skewed scan output from a penta assembly in an instrument that scans a beam in a predetermined fashion. The penta assembly has first and second beam directing surfaces supported at a predetermined angle to each other. A laser beam source directs a beam along a path preferably coinciding with the scanning axis of said mount toward the first surface, and a first optical element converges the input beam to a spot on that first surface. Then the reflection or redirection of such spot is transmitted onto the second surface, and finally the redirected beam from that second surface is transformed into a collimated output beam from the penta assembly. This is accomplished using simple passive optical elements, e.g. convex lenses or optical equivalents, which are readily incorporated into the penta assembly.
