Hi again. I posted a question about this to the telescope making discussion, but got no takers. Hoping to have better luck here.
Many of the bigger binoculars, especially higher end ones, seem to have fixed barrels, and allow for interocular distance adjustment by rotating their porro prisms. Lots of large military units do the same thing. Anyway, what I want to know is whether anyone knows if the rotations are always completely independent for each eye (which could lead to images not unifying?) or can be linked, say by gear teeth or other mechanism. Thanks.
