  • Lighting lens for biometric measurement device
    Patent number: 9719661
    Abstract: A lighting lens for a biometric measurement device comprises a paraboloidal or ellipsoidal reflector with symmetry of revolution, and a dioptric surface that has two different refractive power values in two perpendicular directions, said two refractive power values being negative or zero. Such a lens can be produced in the form of a block of transparent material and be used in a biometric measurement device. In particular, it makes it possible to capture skin prints as an image with an exposure time that is short.
