FIS4-NIR-C Near-Infrared Wavefront Sensor (Refrigerated Version )

In near-infrared optical detection, the temperature rise of equipment during prolonged continuous operation has always been an 'invisible interference' affecting the authenticity of data. The FIS4-NIR-C near-infrared wavefront sensor (Refrigerated Version ), developed by a research and development team led by Professor Yang Yongying from Zhejiang University, integrates a liquid cooling system based on near-infrared optimization, achieving a dual breakthrough of 'precise measurement + long-term stability'.

This product is suitable for aberration measurement of optical systems, calibration of optical systems, measurement of internal lattice distribution of materials, metasurface, and metrolens wavefront measurement. Based on the four-wavefront lateral shearing interferometry technology, it can obtain bidirectional wavefront information with a single acquisition without the need for a reference mirror. At the same time, it adopts liquid cooling to effectively suppress data fluctuations caused by temperature rise during equipment operation, significantly improving the stability of long-term continuous measurement. It can be used with a dedicated liquid-cooled radiator, perfectly adapting to scientific research and mass production scenarios that require higher wavefront stability.

Paired with our fully self-developed analytical software, users can quickly get started without requiring complex configurations. Simply install the software and insert the encryption key. The software boasts a user-friendly and intuitive interface, supporting synchronous visualization of multiple dimensions of data such as 3D topography, contour maps, phase maps, and focal spot intensity. It enables real-time dynamic acquisition and presentation of wavefront changes, facilitating users to intuitively grasp the status of optical components and beams. With a comprehensive built-in data analysis module, it can automatically output core measurement parameters such as PV, RMS, POW, PSF, OTF, and MTF, significantly enhancing data processing efficiency and making complex near-infrared wavefront data processing efficient and intuitive.

From laboratory technology breakthroughs to industrialization implementation, the FIS4-NIR-C near-infrared wavefront sensor (Refrigerated Version ) has achieved full-chain domestic independent research and development, spanning from core algorithms and hardware design to supporting software. Its performance rivals that of similar international products. Meanwhile, relying on rapid response localized technical support and flexible customized services, it truly breaks through the technical barriers and service limitations of overseas brands. With seventeen years of technological accumulation and self-controllable strength, it helps the global near-infrared optical industry break through measurement bottlenecks.
