• Collaboration with Research Institutions:

At the heart of Xuanlei Optical’s innovation strategy is its deep collaboration with academic and research institutions. Since 2018, the company has maintained a formal partnership with the Chinese Academy of Sciences’ Shanghai Silicate Research Institute (SICCAS), focusing on the development of novel electro-optical materials. This joint R&D initiative led to the breakthrough synthesis of a new type of doped barium fluoride crystal with enhanced UV transparency and thermal stability—ideal for use in high-power pulsed lasers. The resulting material was patented in 2023 and is now being commercialized under the brand name XLO-BF300. This success story exemplifies how university-industry cooperation accelerates the industrialization of cutting-edge scientific achievements. Another significant outcome of this collaboration was the development of a low-loss MgF₂ coating process optimized for extreme environments, which was successfully tested in satellite-mounted spectrometers launched by China’s Long March 5 rocket program. The coating demonstrated zero degradation after 1,000 hours of simulated space exposure, validating its suitability for long-duration missions. Furthermore, Xuanlei has established an internal R&D center equipped with state-of-the-art characterization tools—including FTIR, SEM, and interferometric surface profilers—allowing for rapid prototyping and quality validation. These efforts have resulted in over 12 patents filed between 2020 and 2024, reinforcing the company’s position as an innovator rather than just a producer in the optical materials ecosystem.

• Focus on Electro-Optical Materials and Devices:

Xuanlei Optical’s forward-looking focus on electro-optical materials positions it at the forefront of the emerging photonics revolution.
