We show that an imperfectly aligned asphere-CGH-measurement leads to artifacts that are indistinguishable from common manufacturing errors such as trefoil and spherical aberration. We apply a machine learning approach to correct for these artifacts.

In optical design with freeform surfaces descriptions of the surfaces are needed that use only few parameters and are suitable for optimisation. Depending on the merit function – spot size or wavefront error – and the position of the surface in t

Today’s high brilliance Laser sources cause huge thermal effects on optical components, affecting process stability. This paper shows the holistic approach to the improvement of objective lenses to minimum thermal effects as focus shift. A new appr

Jenoptik Laser, Optik, Systeme GmbH has developed a new mounting technology for optical elements. It is free of any glue or other organic material whereby it is excellently appropriate to the use for DUV Systems, especially if high intensity occurs a
