The 12th High Level Expert Meeting (HLEM) will be held online again this year – on MARCH 15 and 16, 2022.
In the field of asphere metrology, many new advancements were achieved, new measurement procedures were developed and precision was noticeably improved. In previous High-Level Expert Meetings (HLEM) and workshops, developers, manufacturers and users have confirmed the great interest in asphere metrology.
In order to manufacture ultra-precise and high-tech optical components and to be capable of further miniaturization, reliable and extremely precise measurement technology is required. Both the introduced measurement systems as well as the results of round robin measurements show the enormous potential of this field of technology. In addition, a great need for comparability, standardization and proximity to users was also pointed out.
The upcoming conference is all about the following topics:
■ Presentation of the results of the round robin
■ New developments in measuring techniques for aspherical, free-form and cylindrical lenses
■ Manufacturing and measurement of metal optics
■ Measurement of unmounted aspheres
■ Inner centration of aspheres
■ Other topics related to asphere and free-form metrology or production
