TS-Optics M48 stainless-steel tuning ring — 0.3 mm
This 0.3 mm stainless-steel ring provides fine spacing adjustment around an M48 × 0.75 filter/imaging thread.
Fit and use
The manufacturer specifies a 49 mm internal diameter so the ring passes over the M48 male thread. It rests between the bearing faces; it is not a threaded extension tube.
Fine adjustment
Use individual thicknesses to tune camera-to-corrector separation or prevent a male thread from bottoming too far into an adjoining component. Keep sufficient thread engagement for the assembled load.
