Machine Vision - Lenses

Machine vision lenses play a critical role in imaging-based automatic inspection and analysis for industrial applications. These lenses are specifically designed to work with hardware systems that enable tasks such as process control, robot guidance, and automatic inspection. They offer a range of focal lengths and types, providing flexibility in adapting the system to different applications. The typical focal ranges offered by machine vision lenses include macro, standard, telephoto, and wide-angle. Macro lenses are used for close-up inspection of small objects and provide high magnification and sharpness. Standard lenses offer a balanced view, suitable for general-purpose applications. Telephoto lenses enable long-distance viewing, making them ideal for applications such as surveillance and object tracking. Wide-angle lenses provide a broad field of view, making them suitable for applications requiring coverage of a large area. Focal lengths of machine vision lenses range from 2.8 mm to 100 mm. The choice of focal length depends on the specific application and the desired level of detail. Shorter focal lengths are suitable for capturing wider views, while longer focal lengths are used for capturing detailed images of smaller objects. The selection of machine vision lenses is based on the compatibility with the image sensor size. The most common image sensor sizes used in machine vision systems include 1 inch, 1/3 inch, 1/2 inch, 1.8 inch, and 2/3 inch. The lens selected must be compatible with the size of the image sensor used in the system to ensure optimal performance and image quality. In summary, machine vision lenses are essential components of hardware systems used for imaging-based automatic inspection and analysis for industrial applications. They offer a range of focal lengths and types, including macro, standard, telephoto, and wide-angle. Focal lengths range from 2.8 mm to 100 mm, and the selection of the lens is based on the compatibility with the image sensor size. The use of machine vision lenses ensures accurate and precise image capture, making them invaluable tools for industrial applications.
