Abstract

Metal mirrors have different advantages in comparison to mirrors made of glassy ceramics and glass elements as they are inexpensive, easy to manufacture and it is possible to integrate reference structures directly into the mirror material. During the last years diamond turning manufacturing of multi mirror freeform substrates became state of the art to reduce the alignment and integration effort of freeform mirror systems. The article gives an overview over the process chain, data analysis, and results from a mirror system for the visual spectral band and provides some theoretical insights necessary for achieving appropriate surface form and roughness values.
