TS ISO 10110-12

TS ISO 10110-12 is the Turkish record for a withdrawn standard on how aspheric surfaces are represented in drawings for optical elements and optical systems. In general technical terms, the subject concerns the clear and consistent documentation of surfaces that depart from a simple sphere. Such surfaces are widely used in optics to improve imaging performance, reduce aberrations, and support more compact optical designs.

Why aspheric surfaces need dedicated drawing notation

From a general engineering perspective, an aspheric surface cannot be fully described by a single spherical radius alone. Drawings therefore need a notation that conveys the intended surface form unambiguously so that designers, manufacturers, and inspectors can work from the same definition. This matters because very small form differences can affect optical performance, especially in precision lenses and high-resolution imaging systems. Clear documentation also supports measurement and quality verification, since the manufactured surface must be compared against the design intent.

Place within the ISO 10110 drawing system

ISO 10110 is a well-known drawing convention for optics and photonics, aimed at standardizing how information is presented on optical component drawings. This part focuses specifically on aspheric surfaces, making it part of a broader documentation framework rather than a standalone design rule. As a result, its value lies in communication: it helps ensure the same optical surface is interpreted consistently across design, fabrication, and inspection activities. Because this listing is marked withdrawn, it should be understood as the record of an older edition associated with the ISO 10110-12 topic, not as a current active publication.

• Standardizes how aspheric optical surfaces are shown on drawings.
• Addresses a surface form that cannot be reduced to a single spherical description.
• Supports consistent interpretation across design, manufacturing, and inspection.
• Especially relevant to precision optics, imaging lenses, and other high-performance optical systems.
