Detailed
Etched Encoder Disc / Optical Scale for OEM / ODM Programs
Etched Encoder Disc / Optical Scale — Custom / Optical Scale
Etched Encoder Disc / Optical Scale is a precision metal part with micro-apertures, fine slots or custom geometry formed directly into SUS304 / SUS301 stainless steel, glass or ceramic — selected by resolution and thermal stability by photo-chemical etching — integrally formed and tooling-free. Its purpose is straightforward: high line counts etched in one pass with ≤0.02 mm concentricity for stable rotation signals.
What is it? High line counts etched in one pass with ≤0.02 mm concentricity for stable rotation signals Typical uses: Photoelectric encoder, resolver code plate
0 mould feeOptical film — revisions need no tooling

Why specify etched Encoder Disc / Optical Scale
Turn Your Encoder Disc / Optical Scale Requirement into a Manufacturable Part
Controllable concentricity and flatness
Concentricity ≤0.02 mm, flatness ≤0.05 mm, reduce rotation runout and phase error.
stress-free deformation
Non-contact chemical cold working, metal code plate sheet shape stability.

Buyer FAQ
Questions Buyers Ask Before Enquiry
Can the line count be tailored to our resolution?
Yes — line count and pitch are calculated from the resolution; changes need only a new film.
Do metal discs distort?
Etching leaves no internal stress; with stress-relief flattening, flatness is ≤0.05 mm and run-out is controlled.
Can you process glass or ceramic?
Yes. Stainless, glass or ceramic can be selected by resolution, thermal stability and cost.
Are high line counts possible?
Line count follows minimum slit width and pitch: 0.03 mm typical, 0.01 mm at the limit.
