The invention discloses an integrating sphere device for optical measurement, relates to the technical field of optical measurement and aims to solve the problems of poor symmetry, ineffective heating control of a light source and non-adjustable flux of a sampling port existing in the conventional integrating sphere device structure. A first half integrating sphere shell and a second half integrating sphere shell of the device are fastened together to form a hollow sphere shell; a central light barrier is fixed at the central position of a joint surface of the first half integrating sphere shell and the second half integrating sphere shell; a joint between an adjustable light source and the first half integrating sphere shell is provided with a sampling hole; a slit device is fixed between the adjustable light source and the sampling hole; a stray light eliminating device is fixed on the second half integrating sphere shell through a screw thread; a position on which the second half integrating sphere shell i
