Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS) is an X-ray fluorescence spectrometer experiment aimed at mapping the abundances of major rock-forming elements on the lunar surface. The instrument consists of swept charge devices with a passive collimator, visible light blocking filters and signal processing electronics designed and built at U.R. Rao Satellite Centre, Indian Space Research Organisation. CLASS will be the largest collecting area spectrometer flown to the Moon, and thus is expected to map the abundances of lunar elements with a higher sensitivity than ever at soft X-ray energies.
