In June 2023, the company undertook a near-field equipment upgrade project for the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP). The equipment was an imported system integrating multiple frequency bands, but it lacked the near-infrared band and could not meet the customer's testing requirements for specific materials. The company helped the research group upgrade and integrate a near-infrared 1064 nm module, and optimized the fiber coupling scheme.
Since the equipment itself is compact, the integration of the new light source had to be designed so as not to affect the original optical path. After several days of intensive on-site debugging, a fourth-order near-field scattering signal was successfully obtained, winning the customer's recognition.
