When selecting a machine vision lens , it is critical not to overlook its importance in the overall system. For example, failure to consider environmental factors may result in suboptimal lens performance and potential damage to the lens; failure to consider resolution and image quality requirements may result in inadequate image capture and analysis. 1 、 I gnoring the importance of the lens in the system A common mistake to avoid when selecting machine vision lenses is to overlook how important the lens is in the system. Here are three key reasons why lenses are critical in machine vision applications: (1) Best image quality The lens plays a vital role in capturing high-quality images. It determines factors such as resolution, distortion, and color accuracy. Choosing the right lens ensures that the system can accurately analyze images and make precise decisions. (2) Proper field of view The lens determines the field of view, which is the area that the camera can capture. It is essenti...

As a key component of the machine vision system, industrial cameras are usually installed on the machine assembly line to replace the human eye for measurement and judgment. Therefore, choosing a suitable camera lens is also an indispensable part of the machine vision system design. So, how should we choose a suitable industrial camera lens ? What issues should be considered when choosing an industrial camera lens? Let's take a look together. 1. Basic considerations for selecting industrial camera lenses ① Choose CCD or CMOS camera according to different applications CCD industrial camera lenses are mainly used for image extraction of moving objects.
