The invention discloses a multi-wavelength day-night total atmospheric spectral transmittance real-time measurement device. According to the device, a plurality of apertures are designed on the front lens cap of a telescope of a star tracking platform, a plurality of optical wedges are arranged between the lens cap and the telescope and are in one-to-one correspondence with the apertures, and a plurality of optical filters with different wavelengths, diaphragms and charge coupled devices (CCD) are sequentially arranged behind the telescope; the diaphragms comprise a plurality of channels; the optical filters, the diaphragm channels and the optical wedges are in one-to-one correspondence; a star beam is divided into a plurality beams after passing through the apertures; each beam sequentially passes through the optical wedges, enters the telescope, passes through the optical filters and the diaphragm channels, and finally reaches the CCD target surface to be imaged into a light spot; and the total atmospheric
