Microscope objective with axially adjustable corrective mounts

摘要

Evenly distributed over a circumference, flat coil springs (FCS) (36) acting in an axial direction fasten with a first ring (37) with pins (39) on-axis. The FCS plug onto the pins that lock into drilled holes in a second ring (38). The first and second rings along with the FCS fitted between them and on the pins form a spring cage that ensures flexible movement in the parts free from play.
