Superior analytical machine science and technology can output the data of the 5nms or the 10nms partition. The special integral-ball structure can availably lower the sensitiver of the instrument on the organization and texture of the color sample. 3.0 millimeters aperture can measure accurately smallest color sample. Five different aperture and the data of the different aperture can contaion a good commutation. Full-automatic flexible lens, full-automatic stationary surface luster-compensate device.
