These compact lenses are designed to provide high image quality with low distortion when the object distance is greater than about 10x the focal length. They are applicable for finite object imaging applications such as face/object recognition, bar-code capturing and bio-medical securities (calculate the lens focal length for your application). Their small sizes make them suitable for hand-held devices. The relative aperture (F/#) can be customized to meet your depth of field requirement (calculate depth of field). We can also integrate auto-focus technologies with these products.
