Extremely large, highly accurate: TNO technologies enabling the construction of the E-ELT
The E-ELT is the European Extremely Large Telescope with a primary mirror of 39 meters that is being developed by ESO for the European astronomical community and ESO members. For the realisation of the E-ELT, TNO Space and Scientific Instrumentation proposes several technical contributions. These are, among others, the mirror support structure, the actuators required for these mirror segments, and optical metrology to control the alignment or phasing. This overview shows how E-ELT technologies are cutting edge while also needing to be robust and low cost for a facility of this size.
