Abstract:
A coating apparatus is revealed that is designed to coat substrates by means of a physical vacuum deposition process or a chemical vacuum deposition process or a combination thereof. Said coating apparatus is particular in that it uses a rotatable magnetron (14) that is coverable with an axially moveable shutter (18). Such an arrangement enables to keep the magnetron target clean or to clean the target in between or even during subsequent coating steps. The shutter further provides for a controllable gas atmosphere in the vicinity of the target. The arrangement wherein the magnetron is centrally placed is described. Substrates are then exposed to the sputtering source from all angles by hanging them on a planetary carousel (24) that turns around the magnetron.
Abstract:
A coating apparatus (100) for batch coating of substrates is presented. In the batch coater layers of a stack can be deposited by means of physical vapour deposition, by means of chemical vapour deposition or by a mixture of both processes. When compared to previous apparatus, the mixed mode process is particularly stable. This is achieved by using a rotatable magnetron (112) rather than the prior-art planar magnetrons. The apparatus is further equipped with a rotatable shutter that allows for concurrent or alternating process steps.
Abstract:
The invention relates to a layered reflector (1) for light radiation comprising: a) a scratch resistant outer layer (2) transmitting this radiation, b) a first resin layer (3) bonded to it, which is provided with slip properties at least at its contact side (7) with the outer layer (2) and which layer c) is covered at its opposite side with a layer (4) reflecting said radiation and which by interposition of a bonding layer (6), d) is laminated to a second resin layer (5) which has slip properties at least at its free outer surface (8) opposite to the contact side with the bonding layer. The invention relates also to a process and intermediate products for manufacturing the reflector as well as a self-adhesive reflector (15) derived therefrom and a light reflecting structure (16).
