Line-scan imaging technology is widely used in continuous industrial inspection. As a critical optical component, the lens directly determines image quality and inspection accuracy; selecting the right lens is key to enhancing the stability of vision systems.

During the selection process, the first step is to match the camera’s sensor size with the lens’s focal length, and then calculate the magnification based on the working distance and field of view to ensure that the target area is fully captured. Second, prioritize line-scan lenses with low distortion and high uniformity, particularly for long-distance, wide-area inspection scenarios, as uniform imaging can significantly reduce the complexity of image processing. Additionally, the lens features an adjustable aperture, allowing for flexible adaptation to varying lighting conditions and ensuring stable exposure during high-speed scanning.

Industrial line-scan lenses utilize a multi-element optical design to optimize light transmission, reduce stray light interference, and ensure consistent image quality from the center to the edges. They are suitable for inspecting continuous roll materials such as paper, film, metal sheets, textiles, and photovoltaic wafers, as well as for defect detection in long components, rail transit parts, and printed materials. With a compact design and easy installation, these cameras offer strong compatibility and can be quickly integrated into various line-scan vision systems. Their stable and reliable optical performance meets the demands of high-precision, high-speed, and continuous inspection in industrial production.
