Bi-metalic strips?  Interesting.  That seems likely to require more
power than a coil, but I'm sure I don't know much about such
engineering.

When testing vendors before choosing one to resell, we did find one of
the big guy's did not work as well on marginal power.  Maybe they used
such bimetalic strips.  Or would you expect more such problems from a
coil?

Prisms?  I'd expect such a design to have higher losses compared to
front-surfaced mirrors, but again, I don't know anything about
designing such a thing.

I think I know at least some (e.g. the one we resell) use magnetic
coils, solenoids.   I think those use flat mirrors, but I'm not
certain.
