TS ISO 10110-8

TS ISO 10110-8 is part of the ISO 10110 series for preparing drawings of optical elements and systems, and it defines how surface texture is indicated in optical technical drawings. In practical terms, it helps specify the residual condition of a polished optical surface after the larger surface form has been separated out.

In general technical use, surface texture describes surface characteristics that can be treated statistically. For optics, this usually matters at two related scales: high spatial frequency roughness and mid-spatial frequency waviness. Those distinctions matter because surface form, texture, and other optical imperfections influence performance in different ways.

How surface texture is positioned in optical drawing practice

Within the ISO 10110 drawing language, this part focuses on how surface texture information is presented consistently on drawings. The method described characterizes the residual surface left after detrending by subtracting the surface form, so the larger geometric shape is separated from finer surface features. That makes it easier for design, manufacturing, and inspection teams to work from the same definition.

Boundaries of the document and related form control

• The document sets rules for indicating surface texture on optical drawings.
• Its primary intended application is polished optics.
• It does not specify control of surface form itself.
• Topics linked to surface form in ISO 10110-5, ISO 10110-12, and ISO 10110-19 are outside this part’s scope.
• The focus is on depicting and defining the residual surface, not on prescribing a manufacturing process.
