Machine Vision Lenses

The lens captures the image and delivers it to the image sensor in the camera. Lens will vary in optical quality and price, the lens used determines the quality and resolution of the captured image. Most vision system cameras offer two main types of lenses: interchangeable lenses and fixed lenses. Interchangeable lenses are typically C-mounts or CS-mounts. The right combination of lens and extension will acquire the best possible image. A fixed lens as part of a standalone vision system typically uses autofocus, which could be either a mechanically adjusted lens or a liquid lens that can automatically focus on the part. Autofocus lenses usually have a fixed field of view at a given distance.
