TS ISO 10110-14

TS ISO 10110-14 is part of the ISO 10110 series for preparing drawings of optical elements and systems, and it deals with how wavefront deformation tolerance is indicated. In optical engineering, the wavefront represents the shape of the light wave relative to an ideal form; this standard focuses on documenting the permissible departure from that desired shape in a consistent drawing language.

The document addresses the deformation of a wavefront transmitted through an optical element or assembly, or reflected from it, and sets rules for how that tolerance is expressed on drawings. In general technical terms, wavefront deformation is closely related to image quality, focus behaviour, and overall system performance in precision optics, where even small departures from the intended wavefront can be significant.

What is covered and what is excluded

The scope includes tolerance indication for wavefronts associated with optical elements or assemblies, and it is also applicable to optical systems using general surfaces. The excluded item is the tilt of the wavefront with respect to a specified reference surface; this part is concerned with shape deviation, not with wavefront orientation.

The standard also states that there is no requirement to indicate a wavefront deformation tolerance. In practice, that means this part provides a common notation framework rather than imposing a mandatory performance limit. It helps designers, manufacturers, and inspectors interpret the same optical characteristic in the same way on a technical drawing.

• Defines how wavefront deformation tolerance is indicated on drawings.
• Applies to transmitted or reflected wavefronts.
• Relates to optical elements, assemblies, and systems with general surfaces.
• Excludes wavefront tilt relative to a reference surface.
• Does not require that a wavefront deformation tolerance be specified.
