7-Dimensional Telescope (7DT)
The 7-Dimensional Telsceope (7DT) is a multi-telescope array that consists of 20 50-cm commercial off-the-shelf (COTS) telescopes. Equipped with 40 medium- band filters of 25 nm FWHM, 7DT can obtain low-resolution spectra with the wavelength range of 400 nm and 900 nm for all the objects within a large field of view (~1.2 square degrees) by taking 2 exposures with each telescope.
