The exhibition has come to a successful conclusion, and our self-developed products continue to move forward

From September 9th to 11th, 2026, the 27th CIOE China Light Expo came to a successful conclusion in Shenzhen. Jingnaike Optoelectronics teamed up with Yucheng Optoelectronics to showcase the core achievement of 100% domestic self-developed FIS4 series high-precision wavefront sensors, and built a real-time optical path demonstration complete measurement link on site. Faced with the import dependence and technological barriers in the high-end optical field, we have provided a new option for the localization replacement of high-end wavefront detection equipment with completely independent core technology.

 Domestic self-developed, expanding long wave infrared detection capability

As the core product of this exhibition, the FIS4 series wavefront sensor received attention from both scientific research and industrial fields during the exhibition. Among them, the newly launched FIS4-FIR-C far-infrared four wave interference sensor is designed specifically for the 8 μ m~14 μ m far-infrared band, further expanding the spectral coverage of the FIS4 series to long wave infrared and expanding the detection capability of the FIS4 series in the long wave infrared field.

In response to the widespread concerns about on-site performance and adaptability, the FIS4 series responds with measured data: with ultra-high wavefront repeatability measurement accuracy, stable operation ability in complex environments of exhibition halls, and complete autonomy and controllability from hardware architecture to analysis algorithms, it demonstrates a reliable level of engineering implementation. The in-depth communication with engineers and R&D personnel from different fields on site has also made us more clear: not only should we achieve independent and controllable core technology, but we should also create high-performance measurement equipment that can truly integrate into production lines and laboratories and withstand practical testing tests.

New and old gather, have a conversation about real testing needs

Although the three-day exhibition has come to an end, the discussion on the landing of technology in the booth remains clear. For us, exhibitions are not only a window to showcase our own products, but also an important platform to continuously connect with customers and gain a deeper understanding of actual project needs.

Thank you very much to our old friends who came here specially. Every discussion on practical applications is an important recognition of our product reliability and technical service capabilities. The improvement suggestions and cooperation demands collected on site have been compiled and recorded, which is the core basis for our subsequent technical iteration and product optimization.

At the same time, we also cherish our first conversation with new friends. The engineering challenges brought by everyone have their own focuses, but the core concerns are highly consistent: how to match the most reasonable solution for specific testing optical paths and environmental limitations, and obtain measurement data with consistency and credibility. Our team has fully initiated communication and will provide targeted solutions as soon as possible to meet the customized needs and cooperation framework for on-site sorting. The exhibition has come to an end, but communication and cooperation have just begun. We look forward to continuing to walk side by side and create a win-win situation!

Optical path testing, demonstrating independent research and development capabilities

True domestic self-developed technology is not only reflected in parameter indicators, but also in practical performance in complex scenarios. At the exhibition site, we set up a measurement optical path for real-time wavefront demonstration: after the beam passes through the sample, the system can achieve millisecond level response, quickly capture the interference pattern to complete Zernike fitting, and output wavefront indicators such as PV/RMS. The personnel in the exhibition hall move frequently and are constantly disturbed by micro vibrations. The demonstration light path still maintains good repeatability and stability, which has been recognized by the visiting audience.

Adhere to the original intention and help the future of optoelectronic intelligent manufacturing

The 27th CIOE China Light Expo has successfully concluded, but the pace of tackling high-end measurement technology and deepening domestic substitution has never stopped. The upper limit of measurement accuracy determines the boundary of precision manufacturing. In the future, we will continue to uphold the tenacious original intention of 100% domestic self-developed technology, overcome more key technologies, and polish more core competitive domestic wavefront detection equipment. Once again, we would like to express our sincere gratitude to all the technical experts, university scholars, and industry colleagues who have visited our booth for guidance! Looking forward to working with you to build a solid foundation for China's optoelectronic industry on the journey of ultra precision optics with independent and controllable precision!
