Abstract
The further development of optical lens production is a continuous optimisation process to improve results and shorten processing times. One approach to this is the adaptation of CNC programmes to produce rotationally symmetrical spherical lenses, as well as processing with additive manufactured tools as an ultra-fine grinding step. This can enable high surface qualities with Rq roughness around 100 nm and lower.
