Abstract

The challenge of building extremely large telescope pushes forward the parallel ability to measure and test optical components of large sizes. Here we present the optical bench setup for the Demonstration Prototype (DP) of the voice coil controlled adaptive mirror M4AU of the E-ELT. A set of three devices has been chosen and used for the tests, whose results are also shown. The performance demonstrated that this is a viable and trusted technology and the DP tests were highly representative of the whole procedure that could be applied to the real, full size unit.
