Theoretical compensation of static deformations of freeform multi mirror substrates
Johannes Hartung, Henrik von Lukowicz, Jan Kinast
Varying temperatures influence the figure errors of freeform metal mirrors by thermal expansion. Furthermore, different materials lead to thermo-elastic bending effects. The articl…
