In this paper we present our current state-of-the-art SPO plate manufacturing process. Special attention is given to the recent advancements in optimizing and upscaling the dicing process, the laser-ID labelling process, wafer-scale automated measurements of plate critical to quality parameters, as well as the lithography process for reflective coating lift-off. Furthermore, the different wedging methodologies and the shift from wetbench processing to spray processing are introduced. The combined efforts in all of these areas enable a more automated plate manufacturing process, and an increase in optical performance of the telescope.
Using a combination of process development and upgraded machinery, the future flight production scenario for NewATHENA begins to take shape.
We present in this paper the status of the optics production and illustrate not only recent X-ray results but also the progress made on the environmental testing, manufacturing and assembly aspects of SPO based optics.
