Optical device, a network for the control, in transmission, by detection of the phase, an optical system, in particular an ophthalmic lens

摘要

This device is of the type comprising, on an optical axis a, the emission means 13 adapted to the construction of a light source 14, a waiting station 15 adapted to the reception of the optical system 10 to control, a network 16, receiving means 17 for the reception of the image observable downstream of the network 16, and the processing means 18 adapted to the use of this image by phase detection. / p & & p & according to the invention, between the standby station 15 and the network 16, is interposed an adapter of convergence 30 and the processing means 18 comprise means able to take account of the aberrations as that of the theoretical due to this adapter element 30 and a ray tracing program. / p & & p & application, in particular, to the control of an ophthalmic lens.
