Lens distortion is the deviation of light rays from a single focus–a flaw in the focusing mechanism that prevents the intended focus. Imaging optical system with aberrations will produce an image that is not sharp. A low distortion lens is a lens that can reduce the degree of perspective deformation.

1/2.7’’ series low distortion lenses provide a large depth of field and wide angle field of views up to 86 degrees, with lens aberration as low as -0.5%, ideal for applications requiring for short working distance such as QR code scanning. The use of lenses in scanning can be seen everywhere in life, like industrial scanners, payment QR code readers, security checkpoints, 3D scanners etc.
