Abstract: The invention relates to an ophthalmic device including an electrically controllable amplitude variation cell, in particular an electrochromic transmission variation cell. More particularly, the cell (3) comprises a main convex surface on the front. This arrangement makes it possible for the cell to process a lateral luminous flux (RP), unlike cells in the prior art (1AA).

Abstract: The invention relates to an ophthalmic device (1) which includes an electrochromic cell (3) comprising at least two transparent layers (4, 5) having curved inner surfaces (4a, 5a) and defining therebetween a closed recess (6) filled with an electrochromic composition (7), the recess (6) being defined peripherally by a sealing gasket (11) made from an adhesive material (20), the sealing gasket (11) being suitable for keeping the two transparent layers (4, 5) assembled together.

Abstract: The invention relates to an ink-jet printing deposition method including a compensation of deviations (?l1, ?l2, ?l3, . . . ) of ejection nozzles (1, 2, 3 . . . ) carried by a printing head (10). To this end, the deviations are measured first at the moment of the deposition, and then, during the deposition, each nozzle is activated when it shows a shift in relation to the point on a support where the substance is to be deposited, substantially opposite the deviation of said nozzle. Said depositions carried out in this way do not comprise accidental Moiré patterns.

Abstract: A method for chemical vapor deposition of a polymer film onto a substrate (6), includes the following two separate, consecutive steps:—a step for the photon activation of the gas phase wherein photon activation energy (42, 43) is provided to at least one gaseous polymer precursor that is present in a mainly gaseous composition, and—a chemical vapor deposition step wherein the activated gaseous polymer precursor, from the photon activation step, is deposited onto a substrate (6) so as to form a polymer film on the substrate, the total gas phase pressure ranging from 102 to 105 Pa. A device (1) for using such a method is also described.

Abstract: A transparent optical component having cells (1) filled with an optical material is proposed, which has a high transparency. The cells of the component are filled to levels (h1, . . . , h5) which vary randomly, and the variations of which are adapted so as not to cause a perceptible optical defect. To do this, the fill levels of the cells are adapted so that the phase shifts experienced by the light rays (R1, . . . , R5) which pass through the cells have a root mean square deviation of less than one quarter of the wavelength (1). Such a component may in particular be an ophthalmic lens.
