To measure the lights scattering at different scattering angles simultaneously by adjusting each detector at 0° position relatively to a laser beam such that all detectors on a rotary table are directed toward a common point at the center of rotation.

In the measuring equipment, a sample 3 in a container 5 containing a liquid 4 having refractive index identical to that of cuvette glass is irradiated from a laser light source 1. The sample 3 is disposed in the center of a rotary table 7 coaxially with the rotational axis thereof and orthogonally to the laser beam. Scattering light from the sample 3 is detected by a large number of detectors 8 juxtaposed on the rotary table 7 at an arbitrary angle. Each detector is adjusted, by respective adjuster, at each 0° position relatively to the laser beam such that all detectors 8 are directed toward a common point at the center of rotation. According to the arrangement, the lights scattering at different scattering angles can be measured simultaneously.
