Arducam, to meet the new demands of working with USB cameras, has selected and tested a wide range of M12 mount lenses, from long focus to wide-angle, to capture images with your USB cameras. Getting the best lens you need is now much easier, and we will continue to expand our list of lenses in the near future.
Introduction
A lens is used to combine light rays in a single image plane on an image sensor for a clear and sharp frame. To understand how to quickly choose the best lens, check out this focal length calculator page. One thing to know about lenses is that the focal length transfers parallel incoming light to a lens.
