TS ISO 10110-6

TS ISO 10110-6. OFFICIAL SCOPE IS UNAVAILABLE. In optics and photonics, this part concerns how centring tolerances are expressed on drawings for optical elements and systems. Centring is the alignment relationship between a component’s geometric axis and the axis that governs its optical behaviour, and that relationship matters because small deviations can influence image quality and system alignment.

Centring in optical drawings

From a general technical standpoint, centring tolerances provide a clear way to state the allowable offset or misalignment that can occur during manufacture. In optical assemblies, even minor decentration may lead to aberrations, beam deviation, image shift, or reduced performance. For that reason, centring information is not just a mechanical note; it is part of the language used to describe how the optical part is intended to function.

Purpose within the ISO 10110 family

The ISO 10110 series is a drawing and notation system for optical components and systems. The general role of this part is to define how centring-related tolerances are indicated so designers, manufacturers, and inspectors can interpret the same requirement consistently. That makes it relevant to lenses, prisms, and broader optical assemblies where axis alignment must be controlled and communicated precisely.

• Centring tolerance describes the acceptable limit of axis misalignment.
• It gives manufacturing and inspection teams a common drawing reference.
• Small centring errors can noticeably affect optical performance.
• This part focuses on the drawing notation for centring in optical components and systems.
