FIS4 requires no professional vibration isolation and quantifies aberrations with a single click, leaving no room for optical distortion to hide.

In the field of precision optics, aberrations are a key factor affecting system performance. From high-end camera lenses to lithography machine objectives, from medical endoscopes to space telescopes, any minute defect in an optical system, whether it is an irregular lens shape, non-uniform material, or assembly error, will lead to wavefront distortion, ultimately affecting image quality and system performance.

The core pain point of traditional aberration measurement methods

• Harsh Environmental Requirements: Relies on strict vibration isolation and constant temperature environments, making stable operation in industrial settings impossible.

• Complex and Inefficient Operation: Requires lengthy setup by specialized personnel; individual measurements are too time-consuming, hindering real-time monitoring.

• Limited Performance and Integration: Insufficient spatial resolution; bulky system and difficult integration into production lines for online monitoring.

FIS4 Wavefront Sensor: A Technological Revolution in Aberration Measurement

Since 2006, Professor Yang Yongying's team at Zhejiang University has dedicated 17 years to the research and development of four-wavefront transverse shearing interferometry phase imaging technology, and launched the wide-spectrum FIS4 series wavefront sensor. By using Zernike polynomials to accurately quantize the wavefront, it provides a breakthrough solution for aberration measurement in optical systems.
