TROPOMI uses a single telescope to focus light onto a spectrometer system consisting of four distinct channels: mediumwave ultraviolet (UV), longwave ultraviolet and visible (UVIS), near infrared (NIR), and shortwave infrared (SWIR). The UV, UVIS, and NIR spectrometers are grouped as the UVN module. To meet specific thermal requirements, radiation for the SWIR channel is transferred from the telescope to the SWIR interface via an optical relay within the UVN system.
