The invention provides an optical system of a close-distance object space telecentric butt-joint sensor, which comprises window glass, a first lens disposed on the rear side of the window glass, a second lens disposed on the rear side of the first lens, a third lens disposed on the rear side of the second lens, an aperture diaphragm disposed on the rear side of the third lens, a fourth lens disposed on the rear side of the aperture diaphragm, a fifth lens disposed on the rear side of the fourth lens, a sixth lens disposed on the rear side of the fifth lens, a seventh lens disposed on the rear side of the sixth lens and a focal plane of the optical system, wherein light rays successively pass through the window glass, the first lens, the second lends, the third lens, the aperture diaphragm, the fourth lens, the fifth lens, the sixth lens and the seventh lens and are then sent to the focal plane of the optical system. In the optical system of the close-distance object space telecentric butt-joint sensor provided by the invention, the independent diaphragm is disposed between the third lens and the fourth lens, which can promote stray radiation suppression of the whole optical system.
