Why is it important?

We describe the spectral design and manufacture of the precision cooled filter coatings for the spectrometer 7 K and imager 9 K.

Perspectives

Details of the design methods used to achieve the spectral requirements, selection of thin film materials, deposition technique, and testing are presented together with the optical layout of the instrument.
