  • Method for manufacturing a set of optical guide microstructures
    Patent number: 12345912
    Abstract: A diamond turning station having a drum able to be rotated about an axis C and a diamond tip. A piece to be machined P is installed on the drum as follows: the piece to be machined P is offset by a distance D from the rotation axis of the drum; the piece to be machined P is placed so that there is a mean angle Theta between the axis C and a cutting profile corresponding to the active surfaces, the angle Theta being as follows: Theta=arccos (D/Ry), where Ry is a radius of curvature required in the long direction of the microstructures. Next, the diamond tip is moved along the cutting profile of the microstructures, while actuating the rotation of the drum, so as to machine all the microstructures on the surface of the piece to be machined P.
