| 摘要 |
The invention concerns a device for automatically measuring characteristics of an ophthalmic lens (L1), comprising: a support (2) designed to receive such a lens; on one first side of the lens support, illuminating means (208) including an optical system for producing a light beam directed towards the ophthalmic lens mounted on said support; and on a second side of the support, means for analyzing (210) the image transmitted by said ophthalmic lens mounted on said support and illuminated by the illuminating means (208); means for splitting the light beam comprising a first mask (220) forming a Hartmann array or the like and arranged on the first side of the lens support to be illuminated, upstream of the lens, by said light beam. The means for splitting the light beam comprise at least a second mask (240) forming a Hartmann array or the like and arranged on the second side of the lens support to be illuminated by said light beam, one of the masks (220, 240) being at least partly releasable.
