Abstract Effective emissivity of the conical blackbody cavity is calculated by Monte-Carlo method, the method is compared with the finite element method.The influence of some factor, such as the geometrical parameters, the emissivity of the material and the distance from the cavity, on the effective emissivity of the blackbody cavity is analyzed. It indicates that the results obtained by the two methods are essentially same, that is, the ratio of cavity length to cavity radius is 6, the opening radius to cavity radius is 0.5, the cone angle is greater than or equal to 90°, the material emissivity is greater than equal to 0.5, the distance from the detector to the cavity is 15 times as large as the cavity radius. At the same time, when all the conditions above are satisfied, the effective emissivity of the conical blackbody cavity is large.
