A National Day Gift | Breaking the Monopoly, the FIS4 Wavefront Sensor Shines with its Core Self-Developed Technology in Chinese Manufacturing!

Seventy-six years of trials and tribulations, seventy-six years of fruitful achievements. On this day of national celebration, the FIS4 team presents a tangible gift to the motherland with its innovative achievements—the fully independently developed FIS4 four-wave shearing interferometry wavefront sensor has officially achieved mass production and been put into application!

Innovation and Breakthrough: Seventeen Years of Hard Work

Since 2006, Professor Yang Yongying's team at Zhejiang University has dedicated themselves to the research of four-wave shearing interferometry. After 17 years of hard work, they have overcome several key technical bottlenecks and launched the wide-spectrum FIS4 series of wavefront sensors. They have obtained multiple national invention patents and formed a complete intellectual property and production system.

Technological self-reliance: The leap from follower to leader

Breaking through technological blockade

100% Chinese-Made Chip: From grating design to core algorithms, completely independent intellectual property rights

Full-Chain Independence: Domestic production throughout the entire process of design, manufacturing, and testing

Breaking the Monopoly: Successfully replacing imported equipment and solving the 'bottleneck' problem

Excellent overall performance

Measurement Accuracy: 2 nm RMS ultra-high detection accuracy, reaching the advanced level of similar international products.

Environmental Adaptability: No vibration isolation platform required, strong vibration resistance, adaptable to industrial environments.

Responsive Service: Fast service response and higher cooperation.

Custom Development: Provides SDK for secondary development of projects, offering customized services according to customer needs.

National Day Gift: Paying tribute to the motherland with innovative achievements.

We firmly believe that core technologies cannot be obtained through begging, buying, or demanding; the Chinese people will surely solve their own problems with their own wisdom, and domestically produced high-end instruments will surely move to the center of the world stage.

Wishing our great motherland prosperity and strength! Wishing Chinese optics continued brilliance!
