Integrating-sphere

The utility model relates to an integrating sphere. The integrating sphere mainly comprises a main body and a diffusion device; wherein, the main body is in spherical shape and is provided with hollow diffusion space; a base is arranged at the bottom of the main body; the diffusion device is arranged in the diffusion space and is equipped with a tapered cone; an incidence hole is arranged at the center of the top of the main body and is used for the incidence of incident light; and an induction probe is arranged at a position corresponding to the incidence hole on the main body for the measurement of the integrating sphere. The tapered cone of the diffusion device provides a better incidence surface for the incident light; due to the arrangement of the base, the integrating sphere can be stably arranged on the ground by the user; in addition, when the incident light source is arranged in the incidence hole, the center of gravity of the incident light source faces the direction of the spherical center in the d
