SING is a near ultraviolet (NUV) spectrograph with a size close to 6U CubeSat form-factor. The spectrograph operates in the wavelength range from 1800 A to 3000 A, with a spectral resolution of 2 A at the central wavelength. The spectrograph is inten

An exciting part of the astrophysical spectrum is the far-ultraviolet (FUV: 90 to 180 nm), with a great density of absorption and emission lines. We are planning to develop an imaging spectrograph incorporated into a 6U (300 × 200 × 100 mm3) satell
