Microscope RMS shims / washers

thingiverse

This is a set of shims for RMS /DIN microscope objectives. Yes they are simply rings, thechnically they are washer or shims. Here uploaded a set of them with thickness 0,1 - 0,2 - 0,3 - 0,4 - 0,6 -0,8 -1,0 - 1,2 - 1,4 _ mm Inner diameter is 20,4mm, outer 26mm. They should fit well on RMS objectives. They are used between the microscope objective and the nosepiece, to finely adjust the parfocality. In the photo, see a microscope objective with a 0,6mm shim on it. Thickness will not come out exact, due to the printer's small errors, so I suggest to print a bunch of them and try them out. Don't worry if they come out wavy, they're so thin, once screwed in they will flatten. PLA is ok. do not print a raft/brim.
