As one of the state key universities directly under the Ministry of Education, Tianjin University, growing out of Peiyang University, is the first institution of higher learning in modern Chinese education. Founded on October 2, 1895, our university is famous for its motto of “Seeking truth from facts” and spirit of “Being strict in teaching” among home and abroad.

On October 2, 1995, the College of Precision Instrument & Opto-electronics Engineering of Tianjin University (called College of Precision Instrument for short), is founded on the base of Precision Instrument Engineering Department (founded in 1959). The predecessor of the Department is Precision Mechanism Instruments Specialty founded in 1952.

The College includes four departments (Precision Instrument Engineering Department, Opto-electronics Information Engineering Department, Biomedical Engineering and Scientific Instrument Department , Opto-electronics Science Technology Department ) and five specialties (Measuring and Controlling Technology and Instrument, Electronic Science and Technology, Information Engineering, Biomedical Engineering and Opto-electronic Technology Science). The College also possesses a state key laboratory of Precision Measuring Technology and Instruments, two ministry key laboratories of Opto-electronics Information Technical Science & Micro-electromechanical system technology. Biomedical detection technology and instrument---A key laboratory of Tianjin, Tianjin Micro-nano manufacturing technology projects center, Tianjin Neural Engineering Research center. In addition, the College has many research and development centers and institutes, such as Precision Instrument Center, Opto-electronics Research Center, Anti-forgery Technology Research Center, Modern Optics Research Institute, Sensor Engineering Research Institute, Illumination Technology Research Institute, Opto-electronic Measuring and Controlling Technology Research Institute, Laser and Opto-electronics Technology Research Institute, Photobiology Research Institute , Space instrumentation and technology research Institute.
