Paper Abstract

In the last 10 years aspheres have readily gone from new products and specialized components to wide acceptance in the market. Successful fabrication of aspheres requires all parts of the process chain including design, production, and measurements. Aspheres now are well-established and accepted as an equal optical element, when done properly. This segment has been the fastest growing market of all optical elements. Research and industry have now started to focus efforts to develop the next new element that propels the field forward in capability, namely the optical freeform surface. An essential factor enabling wide use of freeforms is communicating requirements. This manuscript provides an example monolithic freeform element using the recently updated relevant parts of ISO 10110. The first manufacturing of this component has been successful, and this manuscript shows the role the ISO standard has played in success. Specifically the description of the complex freeform element, as well as definitions for toleranced parameters such as surface registration (centration) and form deviation (irregularity, slope, Zernike, pv, and pvr), are indicated. The provided example also shows how to use the defined datums and definitions for metrology and data handling.
