What is ISO 10110‑12- Presentation of aspheric surfaces about?
ISO 10110‑12 specifies rules for the 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.
Note 1: For off-axis aspheric and non-symmetric surfaces, see ISO 10110-19. ISO 10110‑12 does not specify the method by which conformity with the specifications is tested.
Note 2: ISO 10110‑12 does not apply to off-axis aspheric and discontinuous surfaces such as Fresnel surfaces or gratings.
Note 3: ISO 10110‑12 does not apply to off-axis aspheric and discontinuous surfaces such as Fresnel surfaces or gratings.
Who is ISO 10110‑12- Presentation of aspheric surfaces for?
ISO 10110‑12 on Presentation of aspheric surfaces s is useful for:
- Opticians
- Optics industry
- Manufacturers of optical elements
- Quality testing labs
- Quality assessors
Why should you use ISO 10110‑12- Presentation of aspheric surfaces?
Aspherical lenses are primarily used in high-end optics to produce sharper images and to reduce or eliminate certain optical flaws.
ISO 10110‑12 provides mathematical formulae for various types of aspheric surfaces. ISO 10110‑12 allows you to specify the chosen formula and the corresponding constants and coefficients in the drawings in a standardized manner.
Users can achieve unambiguous indications of the surfaces, sign conventions, surface description, the coordinate system for the constants and coefficients using guidance specified in ISO 10110‑12.
Also, ISO 10110‑12 lets you present indications of surface form tolerance, centering tolerances, and surface texture tolerance for aspheric surfaces.
What’s changed since the last update?
ISO 10110‑12:2019 supersedes BS ISO 10110‑12:2007+A1:2013, which is withdrawn.
The main changes compared to the previous edition are as follows:
- The document has been updated with respect to surface form tolerances as described in ISO 10110-5
- The reference to the new part ISO 10110-19 has been added
- The document has been restructured
- A few surface descriptions have been added
