In 2027, the European Space Agency (ESA) is planning a satellite mission to analyze the Earth's heat balance. The spectrometer required for this, which enables precise measurements in the extreme far infrared range, is being developed in the FORUM project. The component of this measuring device is a beam splitter that is transparent for this extreme bandwidth over the entire spectral range. 
This was realized at the Fraunhofer IOF with the help of researchers from the IAP. 

The first airworthy components have already been delivered.
