Bay Jay Ray Technology Limited (BJR) was established in 2018 with offices in The Hong Kong Science Park in Hong Kong and Shenzhen Research Institute, The Chinese University of Hong Kong (CUHK). BJR focuses on developing high-speed, high-precision, and highly compact optical imaging instruments for precision metrology and biomedical applications. Within three years, the company team has built a complete university technology transformation model with the support from CUHK and local governments. As a spin-off of CUHK, BJR has developed many independent core intellectual property rights and completed the development of the third-generation portable quantitative phase imaging prototype, which has entered practical applications in scientific research and industry. Our company has built good relationships with research institutes, hospitals, and local companies within the Great Bay Area.
