GLAZING HAVING A COMMUNICATION WINDOW FOR SENSORS AND CAMERA SYSTEMS
A glazing includes a first pane with an exterior-side surface and an interior-side surface, wherein a coating made of diamond-like carbon (DLC) is arranged on the exterior-side surface with an atmospheric pressure chemical vapor deposition method.
1 . A glazing comprising:
a first pane with an exterior-side surface and an interior-side surface,
wherein
the first pane contains or consists of soda lime glass, and
a coating made of diamond-like carbon is arranged on the exterior-side surface.
2 . The glazing according to claim 1 , wherein the coating is arranged on the exterior-side surface of the first pane with an atmospheric pressure chemical vapor deposition method.
3 . The glazing according to claim 1 , wherein the first pane is monolithic.
4 . The glazing according to claim 1 , wherein the coating is arranged in some sections on the exterior-side surface.
5 . The glazing according to claim 1 , wherein an area of the coating is from 0.1% to 95% of an area of the exterior-side surface of the first pane.
6 . The glazing according to claim 1 , wherein the diamond-like carbon of the coating includes or consists of a mixture of sp 3 - and sp 2 -hybridized carbon with a proportion of at least 20% of sp 3 -hybridized carbon.
7 . The glazing according to claim 1 , wherein the coating is doped.
8 . The glazing according to claim 1 , wherein the coating has a thickness d of 1 nm to 20 nm.
9 . The glazing according to claim 1 , wherein the coating has higher scratch resistance than the exterior-side surface of the first pane.
10 . The glazing according to claim 1 , wherein the interior-side surface of the first pane is joined flat to an exterior-side surface of a second pane via at least one thermoplastic intermediate layer.
11 . A glazing arrangement, comprising:
a) a glazing according to claim 1 and
b) at least one optical sensor or at least one camera system, whose beam path is directed through the region of the coating.
12 . The glazing arrangement according to claim 11 , wherein the region of the coating completely contains a passage region of the beam path.
13 . A method for producing a glazing according to claim 1 , comprising the following steps in the order indicated:
a) annealing or bending at least one first pane,
b) depositing a coating made of diamond-like carbon on the exterior-side surface of the first pane with an atmospheric pressure chemical vapor deposition method.
14 . The method according to claim 13 , wherein prior to step b) an adhesion layer is deposited on the exterior-side surface of the first pane, and the coating is deposited in step b) on the adhesion layer.
15 . The method according to claim 13 , wherein the coating is deposited out of a plasma nozzle on a subregion of the exterior-side surface of the first pane.
16 . The method according to claim 13 , wherein, after step b), all following steps for producing the glazing ( 10 ) are carried out at a temperature of less than 400° C.
17 . A method comprising providing the glazing according to claim 1 in a vehicle of locomotion for travel on land, in the air, or on water, or as built-in part in furniture, appliance, and building, having optical sensors and camera systems, whose beam path passes through the region of the coating.
