    摘要： The invention relates to a method for manufacturing an optical element according to a prescription comprising the following steps :
    - providing (S1) a combination (CB) of a block piece (B) and a lens blank (SFB) having a first face (cx) and a second face (cc) opposite to the first face (cx), the lens blank (SFB) being blocked with the first face (cx) on the block piece (B),
    - surfacing and polishing (S2) the second face of the lens blank,
    - cleaning (S3-W/-R-S6) the lens blank,
    - hard coating (S7) the second face of said lens blank,
    - degassing (S8) the lens blank,
    - applying (S9) an AR-coating in a vacuum box coater,
    - deblocking (S10) the processed lens blank from said block piece,
    wherein said cleaning step comprises
    - a pre-cleaning step (S3-S4) including a finishing drying step allowing the lens blank to be put on hold,
    - a deep cleaning step (S5-W/-D-S6) prior to the hard coating step.

    摘要： A method and apparatus for blocking an unfinished optical lens member on a blocker for manufacturing an optical lens from the unfinished optical lens member, the latter being provided with a finished surface having a first reference frame, the blocker having a second reference frame, includes: placing the unfinished optical lens member on the blocker; measuring the relative positioning of the first reference frame of the finished surface of the placed unfinished lens member with respect to the positioning of the second reference frame of the blocker; comparing the measured relative positioning with a predetermined relative positioning to determine a relative positioning shift; moving at least the blocker and/or the lens member to change the relative positioning of the first reference frame with respect to the second reference frame to compensate for the relative positioning shift; and blocking the unfinished lens member on the blocker at the changed relative positioning.

    摘要： Provided is an apparatus for detaching a lens from a holder, with which the lens can be detached from the holder easily and quickly without causing a problem such as cracking of the lens.
    A lens separating apparatus 1 is an apparatus that separates a lens attached to a holder 104 via an alloy 102, the lens separating apparatus 1 including: a fixing mechanism 4 that fixes the holder 104; and a separating member 18 that is rotatable around a shaft 16A. A lens material 100 is attached in a state in which at least a part of the outer periphery thereof extends out from an edge of the alloy 102, and the lens material 100 is separated from the alloy 102 by rotating the separating member 18 in a direction of separating the lens material 100 from the holder, in a state in which the holder 104 is fixed by the fixing mechanism 4 and in which the separating member 18 is in contact, from the holder 104 side, with an extended portion of the lens material 100 on the opposite side to the shaft.
