VFI Interferometric Inspection System

The VFI Interferometric Inspection System from Arden Photonics is a high-precision fiber end-face inspection solution designed to rapidly evaluate the quality, flatness, and geometry of cleaved or polished optical fibers. Suitable for fibers ranging from 125 μm to 2000 μm in diameter, the VFI series enables users to inspect and analyze fiber end faces with exceptional detail, helping to improve manufacturing processes, maintain quality standards, and optimize fiber preparation techniques.

Specifically developed for the inspection of optical fiber end faces, the VFI uses interferometric measurement technology to provide detailed information about surface quality and end-face characteristics. The system allows users to examine fibers using multiple viewing modes, including both two-dimensional and three-dimensional displays, giving engineers and technicians a comprehensive understanding of their cleaving and polishing processes.

The VFI is capable of measuring a wide range of standard and specialty fibers, including polarization-maintaining (PM) fibers and hollow-core fibers. Its flexibility makes it a valuable tool across research laboratories, manufacturing facilities, and quality assurance departments. By providing fast and reliable measurements, the system helps users identify process variations, verify fiber quality, and maintain consistent production standards.

One of the key strengths of the VFI platform is its ability to present inspection data in multiple formats. Users can switch between inspection images, fringe patterns, height maps, and three-dimensional visualizations to gain deeper insight into fiber end-face quality. This comprehensive approach allows potential defects, polishing issues, and cleaving imperfections to be identified quickly and accurately.

The system is designed for speed as well as precision. Real-time 2D measurements allow immediate visual inspection, while detailed 3D measurements can be completed in less than seven seconds. This rapid measurement capability supports efficient production workflows and minimizes delays in quality control procedures.

In addition to advanced measurement capabilities, the VFI offers flexible data handling and reporting options. Height data can be exported as CSV files, while measurement results can be generated as Excel or HTML reports, making it easy to archive results, share findings, and integrate inspection data into existing quality management systems.

Over the years, the VFI Interferometric Inspection System has established itself as a trusted solution in research, production, and quality assurance environments. Its combination of measurement accuracy, ease of use, and broad application range makes it an essential tool for organizations working with optical fibers and fiber-based devices.
