Thermo Spectra IR objective

I'm trying to take apart this mirror objective. The silver ring is frozen and it's supposed to turn. The center smaller mirror is foggy, so I want to look at it. The bigger outer mirror looks fine.
But now that I'm down to the mirror holder and the brass center, and the silver out ring knob; I can't find another screw to remove. The brass has threads against the inner silver ring. So I assume turning the ring is supposed to raise or lower the mirror or mirrors somehow.
The three springs seem to suggest the movement is between the top removed lid and the whole assembly that does not seem to be cooperating with my disassembly efforts.
