A fixed focal lens is an optical imaging lens with a constant focal length, meaning the field of view cannot be adjusted. Unlike zoom lenses, fixed focal lenses feature a fixed optical design and typically achieve distortion rates as low as < 0.1% ~ 0.5%, delivering optimal imaging performance at a specific focal length.
