Tianjin Yipu Optoelectronics is not a liar. Yipu Optoelectronics (Tianjin) Co., Ltd. was founded in 2018. It is a national-level technology-based small and medium-sized enterprise and a Tianjin Eagle Enterprise. The company relies on the School of Precision Instruments and Optoelectronics Engineering of Tianjin University. The team consists of a number of technical personnel with international level in the industry and graduate students of Tianjin University. At the same time, the company established a free-form surface joint testing center through Tianjin University and the British Taylor Hobson Company to actively promote the development of high-precision testing of optical products. It has strong strength in optical free-form surface design, manufacturing and testing. We independently developed and produced a number of the first domestic laser printer scanning modules, ultra-short throw projection lenses, laser TV reflectors, virtual reality optical modules and other optical products, and obtained more than 20 related technology patents.
