FA Lens Definition and Characteristics

FA lenses are fixed aperture lenses whose aperture size remains constant as the focal length of the lens changes. This characteristic gives FA lenses a unique advantage in machine vision inspection.

FA Lens Features

1. High resolution: FA lens adopts high-quality optical design, which can provide high-resolution images to meet the requirements of machine vision system on image clarity and detail.

2. Low aberration: aberration is one of the important factors affecting the inspection accuracy of machine vision, FA lenses effectively reduce image aberration by optimizing the optical design, which improves the accuracy of measurement and positioning.

3. Large aperture: FA lenses usually have a large maximum aperture, which can provide more light intake, making it possible to capture bright images in low-light conditions. This feature is especially important in high-speed applications, as a large aperture can be used with ultra-short camera exposures to provide better imaging results.

4. Compact design: FA lenses are usually designed in a compact form factor, which facilitates installation and commissioning, while reducing the footprint and improving the overall flexibility of the machine vision system.

Advantages of FA lenses in machine vision inspection

1、Improve detection accuracy: The low distortion and high resolution characteristics of FA lens make the machine vision system able to recognize, measure and locate objects more accurately, which improves the precision and reliability of detection.

2、Enhance adaptability: The large aperture design of FA lens makes the machine vision system able to maintain stable imaging effect under different lighting conditions, which enhances the adaptability and robustness of the system.

3、Enhance inspection efficiency: The compact design and high quality imaging of FA lens makes the machine vision system able to complete the inspection task quickly and accurately, which improves the production efficiency and automation level.
