Optics and photonics — Electronic exchange of optical data — Part 1: NODIF information model

Edition date: 2012-03-02
In Force
Available languages: English
Summary:

This part of ISO 25297 specifies the information requirements for optical systems and parts, and provides an

information model to support the processes of optical design, optical evaluation and analysis for these optical

systems and parts when using computers with CAD and CAE.

NOTE Generally, an optical system means an optical unit as an optical product, which performs optical functions,

and is composed of optical elements and the barrels in which these elements are mounted. In this part of ISO 25297, an

optical system is a collection of optical parts and optical assemblies, e.g. the viewfinder system or the taking lens system

of a leaf shutter camera.

This information model adds the data peculiar to optical design specification based on STEP to ISO 10303

(all parts). The additional information is product specification information, optical design information, optical

evaluation information and analysis information.

This part of ISO 25297 is generically called the Neutral Optical Data Interchange Format (NODIF).

The following are within the scope:

— information on product specification, optical design, optical evaluation and analysis;

— optical systems and parts in imaging systems, such as cameras and copiers, viewing systems for

telescopes and microscopes and the other optical systems, such as projectors and pick-up lenses;

— multiple-configuration optical systems, including zoom lenses and inner focusing systems;

— optical path definition, including ray-path sequence and optical surface arrangement;

— optical assemblies, including cemented parts and dynamic parts;

— mathematical description of the optical surface form;

— description of diffractive surfaces;

— machining process designation, such as polishing, molding or replicating;

— optical material specifications, such as material names, lot numbers and measured refractive indices;

— optical tolerances for the shape and material property of each optical part;

— assembly tolerances, such as separation, parallelism, displacement and tilt.

— effective diameters, coatings and protective surface treatment;

— paraxial evaluation, such as focal length, back focal length, principal points and f-number;

— ray-tracing evaluation, such as geometrical ray-tracing results (i.e. ray directions and intersection points

on each surface and optical path lengths), aberrations and wavefront aberration;

— OTF evaluation based on geometrical and/or physical optics;

— illuminance distribution on a detection surface or a projection surface;

— spectral characteristics;

— ghost image evaluation;

— thermal analysis accompanying optical surface deformation and material property value change;

— stress analysis accompanying optical surface deformation and material property value change;

— veiling glare and surface imperfections.

The following are outside the scope of this part of ISO 25297:

— mechanical design, electronic design and embedded software design;

— optical systems in which the optical path is changeable, e.g. beam splitters or variable magnification converters;

— tolerances for mechanical parts;

— parts with a diameter less than 10 times the wavelength of light;

— parts made from materials whose dielectric constant, σ, electric permittivity, ε, and magnetic permittivity,

μ, are uninfluenced by interaction between the materials and the light;

— graphical documents resulting from design, evaluation and analysis of products;

— optical wave guide for optical communications;

— product planning information concerning market research and customer analysis;

— product definition and configuration control information irrelevant to design, evaluation and analysis;

— analysis information, except thermal and stress analysis, e.g. vibration analysis;

— information on trial production, production process including production planning and production control,

and processes after production, such as shipment and repair;

— ophthalmic optics.

Frequently Asked Questions Do you have any questions about our products?
  • Standards UNE, EN, ISO, IEC, BSI, DIN, ASTM, AFNOR, IEEE, SAE
  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.

Once the "Customer data" form has been completed, "Order in progress" will be displayed with all the items loaded in the shopping cart, their prices, taxes established in current legislation and shipping costs if applicable.

The prices of the standards and books that appear in the various sections do not include taxes or shipping costs.

AENOR promotional codes consist of alphanumeric characters and can only be applied to online purchases, received through a specific offer and for a limited time. To apply your promotional code, you just have to enter it in step 2 of 4 of the purchase process on the website and click on "apply", after you have identified yourself and chosen the payment methods. Promo codes are not cumulative.

 

  • Credit or debit card (Visa, Mastercard) and PayPal.
  • Bank transfer. If you opt for this form of payment, you must first send AENOR a copy of the transfer by email to normas@aenor.com
  • The purchase invoice can be downloaded from the customer area, in my previous orders

In the case of clients of companies based abroad, the taxpayer identification number of the corresponding country (for example, in Argentina the CUIT), must be filled in the CIF/NIF - VAT field .

  • Direct download via the website in the Customer Area. In the customer area, which can only be accessed with a password and username, the products purchased will be available for a period of fifteen days from the date of purchase, as long as the payment has been accepted. Files in digital format are protected and in no case editable.
