Haxunda (Weihai) Optoelectronic Technology Co., Ltd. is a high-tech company that transforms the research achievements of Harbin Institute of Technology, committed to promoting internationally leading laser optoelectronic technology and its application products to the global market. Harbin Xunda Optoelectronics is led by Professor Tian Zhaoshuo, a doctoral supervisor at Harbin Institute of Technology and director of the Ship Sea Optoelectronic Equipment Research Institute. The research team has developed a series of products with independent intellectual property rights, including miniature laser spectrometers, food spectral detectors, water quality and oil pollution monitoring instruments, etc. The water quality and oil pollution monitoring device adopts laser spectroscopy core technology, which has many advantages such as high sensitivity, high accuracy, multi parameter, and small size. The monitoring methods include contact, non-contact, or remote methods. The onboard platforms include airborne, shipborne, unmanned aerial vehicles, shore stations, etc. The real-time online monitoring system for water quality and oil pollution based on this technology has solved the problems of real-time monitoring of water quality and real-time alarm of oil spills for marine and water conservancy environmental protection departments and related enterprises and institutions in many parts of the country, and significantly reduced the cost of monitoring work. HaXunda continues to invest heavily in research and development in the field of laser optoelectronic technology applications, promoting innovation and upgrading, continuously creating value for the entire industry and society, and enabling more organizations, institutions, individuals, and families to benefit from the reliability and convenience brought by laser optoelectronic technology applications. HaXunda insists on opening up boundaries, shaking hands with the world, and establishing an industrial environment of "mutual growth, symbiosis, and regeneration" with customers and partners to achieve a win-win situation of social and commercial value.
