A zoom lens is a lens that can change the size of an image by adjusting the focal length. It is able to zoom in or out on the subject without changing the camera position, and plays an important role in the industrial field.

Zoom lenses play an important role in industrial inspection and quality control. During the manufacturing process, products need to be inspected and measured in detail. Zoom lenses are able to capture parts of varying size and detail by quickly adjusting the focal length without moving the camera or adjusting the equipment. This flexibility makes zoom lenses ideal for industrial quality control, helping to increase productivity and reduce defect rates.

For example, zoom lenses play an important role in applications such as clothing character labelling, air conditioning compressor core wall inspection, detection of dirty defects in workpiece bores, and inspection of electronic communication components.

Zoom lenses also play a key role in industrial positioning systems. Position guidance is required in many automated operations to ensure the smooth running of the production process. Zoom lenses can be quickly adjusted when needed to capture details of different areas, provide clear, accurate images, and quickly acquire positional information to help identify and solve problems in a timely manner.

The application of zoom lens in industry is very wide and diverse. It plays an important role in industrial inspection and quality control, positioning and guidance. By adjusting the focal length, zoom lenses are able to provide images of different sizes and details, helping to achieve accurate inspection, monitoring and display. Therefore, zoom lenses have great potential to improve productivity, ensure product quality and promote industrial development.
