TS ISO 10110-2

TS ISO 10110-2 is the part of the ISO 10110 series that addresses how material imperfections are shown on drawings for optical elements and systems, with a focus on stress birefringence. It relates to the way optical parts are specified for manufacture and inspection, so that information about birefringence caused by internal stress is communicated in a consistent drawing format. The standard is withdrawn, but the technical topic remains important wherever transparent optical materials must preserve predictable performance.

Why stress birefringence matters in optical drawings

Stress birefringence occurs when mechanical stress inside a material changes its optical response differently along different polarization directions. In optical components, that can affect image quality, phase behavior, and measurement consistency. Recording this information on a technical drawing helps align design intent, manufacturing practice, and inspection expectations. In general technical context, it is one of the key material-quality indicators used for optical glass and other transparent components.

Place within the ISO 10110 family

This part belongs to the broader ISO 10110 approach for presenting design and functional requirements on technical drawings for optical elements and systems. The family is intended to standardize notation for manufacture and inspection, reducing ambiguity between organizations. In TS ISO 10110-2, the scope is specifically the presentation of stress birefringence as a material imperfection; it does not cover the full range of optical defects or every possible drawing convention.

• A drawing-notation part for optical elements and systems.
• Covers the presentation of stress birefringence under material imperfections.
• Supports manufacturing and inspection by using a common specification format.
• Forms part of the larger ISO 10110 series for optical drawings.
