DIOPTIC participates in the High Level Expert Meeting (HLEM) on precise Asphere Metrology. The event is organized by the Competence Center for Ultraprecise Surface Processing (CC UPOB e.V.). Due to the ongoing coronavirus pandemic, this year’s HLEM will be held exclusively as a digital event. With our presentation on the topic: “Measurement of Inner Centration of an Asphere with CGH Compared to the Optical Profilometer LuphoScan”, we actively contribute to the expert meeting.
