Abstract
An ophthalmic lens scanner includes an inspection platform configured to receive an ophthalmic lens thereon. A camera is spaced apart from the inspection platform and is arranged to, in response to an activation signal, capture an image of the ophthalmic lens. A light source is spaced apart from the inspection platform and is configured to emit light when the camera is activated to capture an image of the ophthalmic lens. The inspection platform is located between the camera and the light source. A first Fresnel lens is located between the inspection platform and the camera. A second Fresnel lens is located between the inspection platform and the light source. The ophthalmic lens scanner may be incorporated in an ophthalmic lens scanner system that includes a computing device and a display device.
