The invention relates to a long-focus transmission-type quasi telecentric three-linear-array stereoscopic mapping optical system. The long-focus transmission-type quasi telecentric three-linear-array stereoscopic mapping optical system comprises three optical subsystems with completely consistent structure forms, wherein each optical subsystem comprises a front lens group (1), a diaphragm (6), a middle lens group (2), a rear lens group (3), a transflective prism (4) and a receiving image surface (5), all of which are sequentially arranged along the light ray incidence direction, the caliber of a radiation beam of a mapping target is regulated after the radiation beam passes through the front lens group (1), the radiation beam is full of the diaphragm (6) to exit, an angle amplification ratio is regulated after the outgoing beam passes through the middle lens group (2) and the rear lens group (3), and the outgoing beam exits to the transflective prism (4), so that the outgoing beam is divided and then is image
