PROBLEM TO BE SOLVED: To facilitate positioning of optical elements and to miniaturize a device by integrally mounting the optical elements, such as light source emitting plural light beams to an object and multiple light reception receiving the light beams from the object on a frame. SOLUTION: An installation section 22 and a second light source section 23 are connected to a main body 21 having a frame section 24, a light source section 25 and light reception sections 26 by auxiliary shafts S1-S4 for forming an optical information measuring device used as a dispersoid analysis device with image pickup function, for example. The light source sections 25, 23 have laser light source of plural prescribed wavelengths, the light source section 25 gives vertical illumination and ultra-illumination with zonal rays, and the second light source section 23 gives transmission illumination. The light reception sections 26 are provided, for example, with light elements, and the frame section 24 is provided with an image pickup element. Image pickup by various illuminations and measurement of scattered light and transmitted light are applied to an object such as a particle-containing sample liquid flowing in a sheath flow cell installed in the installation section 22, for example.
