UKRI-1659 METIS - Integral Field Unit (IFU) Components

The European Extremely Large Telescope (ELT), currently under construction in Chile, will be the world’s largest telescope operating in the visible and infrared wavelength domain. It is part of the European Southern Observatory (ESO), an inter-governmental research organization. METIS is an imager and spectrometer for the (ELT), operating at wavelengths of 2.7 micron to around 14 micron. The integral field unit (IFU) is an all reflective image slicing IFU with 28 slices. It is intended that the optical components of the IFU will be manufactured using single point diamond machining to generate the multiple mirror facets on monolithic components.
