A method for locating, in a deposition line including a succession of compartments, an origin of a defect affecting a stack of thin layers deposited on a substrate in the compartments, in which each thin layer is deposited in one or more successive compartments of the deposition line and pieces of debris remaining on the surface of a thin layer deposited in a compartment act as masks for the subsequent depositions of thin layers and are the origin of defects, includes obtaining at least one image showing the defect, determining, from the at least one image, a signature of the defect, the signature containing at least one characteristic representative of the defect, and identifying at least one compartment of the deposition line liable to be the origin of the defect from the signature of the defect and using reference signatures associated with the compartments of the deposition line.

Method and device for locating the origin of a defect affecting a stack of thin layers deposited on a substrate

A glazing includes a transparent polymer material sheet having a thickness of from 5 to 25 mm and a glass sheet having a thickness of between 0.5 and 1.5 mm, which are bonded to one another by an adhesive interlayer, the hardness of which at a temperature at least equal to &#x2212;5&#xb0; C. is at most equal to 70 Shore A and the thickness of which is a decreasing function of the thickness of the glass sheet, an adhesive interlayer thickness of 2.5 mm being sufficient for a glass sheet thickness of 0.55 mm and an adhesive interlayer thickness of 1.25 mm being sufficient for a glass sheet thickness of 1.25 mm.

Laminate of a thick polymer material sheet and of a thin glass sheet

Electrochemical system comprising at least one substrate of organic nature, at least one electronically conductive layer and at least one active species, characterized in that it includes at least one organic layer lying between the electronically conductive layer and the substrate.

Electrochemical system on a plastic substrate

The subject of the invention is an element having variable optical properties, comprising: It applies especially to the manufacture of backprojection screens.

Electrically controllable device having variable optical qualities or system which is holographic, thermotropic or which has suspended particles

Electrically controllable device having variable optical/energy properties in transmission or in reflection, comprising at least one carrier substrate provided with a stack of electrochromic functional layers, including at least two electrochromic active layers, separated by an electrolyte, said stack being placed between two current leads, namely the lower current lead and the upper current lead respectively ('lower' corresponding to the current lead closest to the carrier substrate, as opposed to the 'upper' current lead which is furthest from said substrate), characterized in that the electrochromic material constituting the two active layers is identical, and this electrochromic material is chosen from those whose coloration is not a linear function of the charge insertion.
