Industrial lens is a key component of the visual inspection system, which can connect the industrial camera and the object to be inspected, so that the image information can be accurately and clearly transmitted to the inspection system.Its performance and applicability have a direct impact on the accuracy and efficiency of the entire system. Understanding the parameters of industrial lenses can help and select the appropriate industrial lens.

 

 

 

Four important parameters of industrial lenses

 

1. Focal length: The focal length determines the magnification of the object being detected and the sensitivity of the lens to the distance of the object. Generally speaking, the longer the focal length, the higher the magnification, but at the same time the angle of view of the lens will also become smaller, resulting in increased sensitivity to the distance of the object. Therefore, when selecting an industrial lens, you need to choose an appropriate focal length based on the actual detection needs and the size of the object being detected.

 

 

2. Aperture: Aperture is a blade device that controls light entering the lens. It directly affects the exposure and depth of field of the lens. Generally speaking, the larger the aperture, the greater the exposure, and the smaller the depth of field; the smaller the aperture, the smaller the exposure, and the greater the depth of field. In the visual inspection system, we need to choose an appropriate aperture based on the actual lighting conditions and the moving speed of the object being inspected.

 

3. Image field size: Image field size refers to the size of the image area that an industrial lens can capture. This parameter is related to the size of the object being detected. The image field size must be larger than the size of the object being detected to ensure that the object can be completely photographed. When selecting an industrial lens, you need to consider the size of the object being inspected and the resolution requirements of the inspection system

 

4. Mount type: The mount type of industrial lenses and industrial cameras is also an important parameter in model selection. Common mount types include C, CS, F, etc. C-mount is the most commonly used mount type and can adapt to most industrial cameras. When choosing an industrial lens, you need to choose a suitable lens according to the mount type of the industrial camera used.

 

 

When selecting an industrial lens, it is also necessary to comprehensively consider these parameters based on the actual inspection requirements and the size of the object being inspected, so as to select the most appropriate industrial lens to ensure the accuracy and reliability of the visual inspection system.
