[Anhui Daily] Clear “core” to Guard the City's Safety

On December 7, the technical team of Laser Chip R&D Center of Hefei Institute of Public Safety, Tsinghua University was carrying out the R&D and debugging of sensors. Facing the major national demand for urban safety, the center actively carries out the laser sensing special chip and high-end sensor technology research and development, successful development of 1653nm combustible gas detection laser chip, the size of only 250 × 250μm, and make such chips yield rate from about 40% to more than 90%.

On December 7, staff of the Laser Chip R&D Center of the Hefei Institute of Public Safety at Tsinghua University assembled and debugged the sensors.

At present, the hospital has built a complete laser chip and sensor pilot platform, production capacity of 1 million / year, more than 30,000 sets of chips in our province, Tianjin, Sichuan and other places of application, to become a guardian of the people's security of the faithful “sentinel”.

Sensors with a clear “core”.

On December 7, technicians from the Laser Chip R&D Center of the Hefei Institute of Public Safety at Tsinghua University calibrated the sensor.

On December 7, laser sensors are undergoing high and low temperature tests at the Laser Chip R&D Center of Tsinghua University's Hefei Institute of Public Safety.

For a long time, by the design, manufacturing, packaging and testing technology and process constraints, China's urban safety gas sensing laser chip industry is highly dependent on foreign imports. In September this year, Tsinghua University Hefei Institute of Public Safety independent research and development of

“urban lifeline monitoring network - gas detection laser chip” in the 2022 World Manufacturing Congress for the global release. Qing “core” laser chip, a breakthrough in the field of gas sensing in China's “neck” technology, to promote the core technology of urban safety independently controlled and the important upgrade of the urban safety industry.
