In today's increasing integration of automation and machine vision, FA lens as an important part of the vision system, its selection is directly related to the accuracy, efficiency and stability of the entire automation project.

FA lens basic parameters:

1, Focal length: the focal length determines the distance between the lens and the subject and the size of the image. In the selection, according to the working distance, field of view and image quality requirements to determine the appropriate focal length.

2, Aperture: aperture size affects the amount of light into the lens and depth of field. Large aperture can increase the amount of light, suitable for low-light environment, but the depth of field is shallow; small aperture is longer depth of field, suitable for the need to clearly show the whole picture of the scene.

3, Resolution: resolution is a measure of the sharpness of the lens imaging key indicators. High resolution lens can capture more details, especially important for high-precision detection.

4, Aberration: aberration is a common phenomenon in lens imaging, including barrel and pincushion-shaped aberrations. In the selection, should try to choose a lens with small aberrations to reduce the difficulty of post-processing.

Application Scenario:

1、Object detection: For scenes that require precise detection of object size, shape or position, high-resolution, low-distortion lenses should be selected to ensure the accuracy of the detection results.

2、Barcode recognition: Barcode recognition has high requirements for the focusing speed and imaging clarity of the lens. Therefore, the lens with rapid focusing and clear imaging should be selected to improve the recognition efficiency.

3、Visual guidance: in the robot visual guidance system, the lens needs to quickly capture and track the target object. At this time, lenses with high-speed response capability and good tracking performance should be selected.

Lens and camera compatibility

Lens compatibility with the camera is a part of the selection process that cannot be ignored. Different brands and models of cameras may have different interfaces and communication protocols, so when selecting a lens, you need to ensure that it is perfectly matched with the camera to achieve the best performance.
