The Laboratory for Astronomical Instrumentation at ETH Zurich has shipped its first cryogenic wheels that were developed for the new infrared instrument ERIS on the Very Large Telescope (VLT) of the European Southern Observatory (ESO). These mechanisms will hold various filters and masks that provide unique capabilities for direct imaging and characterization of exoplanets.
