1/2.7’’ series scanning lenses are wide angle low distortion lenses, capturing up to 110 degrees horizontal field of view with less than -1.2% lens aberration. Their large depth of field keep more of the image sharp and clear. Moreover, they are available in various apertures from F/2 to F/6. For a given subject framing and camera position, the DOF is controlled by the lens aperture diameter. Reducing the aperture diameter (increasing the F-number) increases the DOF. In addition to the characteristics mentioned above, another main feature of these lenses is their compact dimension. With Short TTL and M8 mount ,this lens is suitable for applications with limited room. wide angle low distortion lenses are widely used in devices with scanning function, such as Loker, Slot Machine, Code Reader, etc.
