The utility model discloses an in-situ continuous direct measurement type optical method dust meter which comprises a dust meter main body, a blowback base connected to one end of the dust meter main body, a laser connected to the other end of the dust meter main body, a circuit board connected to the laser and a calibration device mounted on the dust meter main body, the laser device is installed on the dust meter body through a receiving end light path base, an optical filter is arranged between the circuit board and the receiving end light path base, the laser device is installed on the upper side of the receiving end light path base, and a plano-convex lens is arranged between the receiving end light path base and the dust meter body. Window glass for preventing sample gas from leaking is arranged at the end, close to the plano-convex lens, of the dust meter main body. On the basis of the original laser back scattering dust meter, the mounting structures of the optical filter and the laser are changed, so
