About This Part

This is a custom lens mount for an optical instrument assembly, and the fine thread is its centerpiece. The M11 x P0.5 clean light thread is cut so a mating lens cell screws in with even, minimal play; coarse threads rock the optic, and a pitch of 0.5 mm turns positioning into a fine adjustment. The thread is gauged, not eyeballed, on every part.

The body dimensions are held to drawing bands of 55.12 +/-0.04, 29.64 +/-0.05 and 13.22 +/-0.05 mm, with the drawing's star-marked dimensions treated as critical controls and inspected one hundred percent. Fastening runs through 2x M2 threads with spring washers, four 2.0 mm holes, a 2.7 mm hole and a 4x 5.7 mm counterbore pattern at 90 degree spacing. One more sub millimeter callout, 0.338 +/-0.03 mm, is held on the same drawing and inspected with the critical set. General tolerances follow the drawing's ISO 2768-m class note.

The finish is a two step system: hard anodize for a wear resistant surface, bead blasted for a uniform matte black texture that scatters stray light and resists showing scratches. Finishing follows final machining so the precise surfaces stay precise; thread and critical dimensions are re-gauged after coating.

Surface standard is explicit, because optical hardware shows every flaw: parts ship clean, burr free, with no scratches or impact marks, and star-marked critical dimensions are verified on the CMM part by part with thread gauges on the M11 and M2 features.

Common Questions

Why a 0.5 mm pitch thread for a lens?

Fine pitch is fine adjustment. Each turn of an M11 x P0.5 moves the mating optic half a millimeter, against more than a millimeter on a coarse thread, so the lens positions precisely and stays put without a locking feature.

What does the bead blast do besides look good?

It micro texturizes the hard anodize into a matte surface that scatters stray light inside the instrument and hides handling marks. Optically it is function, not decoration.

What tolerances can you hold on new optic mounts?

The drawing's own callouts govern. Send the tolerance band together with the mating lens cell, and we will confirm feature by feature what can be held after coating, before quoting.
