Optics and photonics - Preparation of drawings for optical elements and systems - Part 12: Aspheric surfaces
This document specifies rules for presentation of aspheric surfaces and surfaces with low order symmetry such as cylinders and toroids in the ISO 10110 series, which standardizes drawing indications for optical elements and systems. It also specifies sign conventions and coordinate systems.
This document does not apply to off-axis aspheric and discontinuous surfaces such as Fresnel surfaces or gratings.
NOTE For off-axis aspheric and non-symmetric surfaces, see ISO 10110-19.
This document does not specify the method by which conformity with the specifications is tested.

About This Item
TS ISO 10110-12 is a part of the ISO 10110 series for preparing drawings of optical elements and systems, and it defines how aspheric surfaces are represented on technical drawings. It also covers surfaces with low-order symmetry, such as cylinders and toroids, together with the sign conventions and coordinate systems needed to describe them unambiguously. The practical aim is consistent communication between optical design, manufacturing, and inspection.
Why the drawing notation matters
In general optical engineering, aspheric surfaces are used to shape wavefronts, reduce aberrations, and achieve optical performance that a simple spherical surface cannot provide. That makes notation especially important: a drawing must identify the intended surface form clearly enough that the same geometry is understood throughout the supply chain. This standard addresses the presentation of that information on drawings; it does not define how conformity is tested.
Defined boundaries of the part
- Off-axis aspheric and discontinuous surfaces are outside the scope of this part, including Fresnel surfaces and gratings.
- ISO 10110-19 is noted for off-axis aspheric and non-symmetric surfaces.
- The document focuses on drawing conventions, coordinate reference and sign usage rather than optical performance limits or verification methods.
