Extreme and far ultraviolet imaging spectrometers will be boarded on the low-altitude satellite of the upcoming mercury msision (the BepiColombo mission) conducted by ISAS and ESA. The UV instrument, consisting of the two spectrometers with common electronics, aims at measuring, (1) emission lines from molecules, atoms and ions present in the Mercury's tenuous atmosphere, and (2) the reflectance spectrum of Mercury's surface. The instrument pursues a complete coverage in UV spectroscopy. The extreme UV spectrometer covers the spectral range of 30-150 nm with the field of view of 5.0 degree, and the spectrum from 130 nm to 430 nm is obtained by the far UV spectrometer. The extreme UV spectrometer employs a Mo/Si multi-layer coating to enhance its sensitivity at particular emission lines. This technology enables us to identify small ionospheric signals such as He II (30.4nm) and Na II (37.2nm), which the previous mission could not identify.
