What tolerance can LusterControl hold on Optical lens barrel & mount?

Update Time:2026/9/5

What you should expect as a buyer

If you are sourcing Optical lens barrel & mount, the single number that decides fit and scrap rate is tolerance. At LusterControl we hold ±0.005 mm on stainless steel mirror-finished parts using 60 CNC machines and in-house turn-mill composite, 5-axis, mirror/electropolishing, Swiss-type turning, lot traceability. For startup / crowdfunded, that means your scratch-free Ra and bore roundness concern is designed out before cutting.

How we prove it

  • First-article report with measured CMM data, not a promise.
  • Every batch carries lot traceability back to material and machine.
  • Mirror finish to Ra 0.6 μm (standard), up to 8K mirror Ra 0.2 μm when surface is part of the spec.

Low-moq prototyping and a fast path to first articles — send us your drawing and we return a free DFM review with the real achievable tolerance.
