I've been straying away from the idea of a monochromator because it
has moving parts, but maybe it could be ruggedized with the right
components. The reason I bring this up is the auto-calibration enabled
by a 2D sensor... makes driving the stepper/servo a bit easier on the
motor control side, right?
TI makes those digital micromirrors... we built a dev kit for one at
work at about 6-12 inches working depth it had a sweep of a good 6
inches up and down. I'm not sure if they sell a chip with just one
mirror though, and I think the coating might be UV absorbent.
Not sure how it could help, but here's an example the 2D mirrors in
projector mode, and in single-pixel camera mode:
