The invention relates to an optical measuring device (1) having a housing (3), in which at least one optical emitter (20) for emitting at least one emission beam (22, 24) and at least one optical receiver are arranged, wherein a cover disc (5) terminates the housing and forms an emission window (10)
The invention relates to an optical measuring device (1) having a housing (3), in which at least one optical emitter (20) for emitting at least one emission beam (22, 24) and at least one optical receiver are arranged, wherein a cover disc (5) terminates the housing and forms an emission window (10) and a reception window (7), wherein the at least one emission beam (22, 24) exits from the housing through the emission window (10), wherein the receiver receives the emission beam, which is reflected from the surroundings, as a reception beam through the reception window (7), and wherein the cover disc (5) has a heating assembly (20), and a corresponding method for producing a cover disc (5) for the optical measuring device (1). To provide an optical measuring device (1) having a heating assembly (20), which does not distort an emission beam as it exits from the housing (3) of the measuring device (1) via the cover disc (5), the heating assembly (20) is arranged essentially in the region of the reception window (7) and the region of the emission window (10) is left out.

1. An optical measuring device, comprising: a housing, in which at least one optical emitter for emitting at least one emission beam and at least one optical receiver for receiving a reception beam are arranged,wherein a cover disc terminates the housing and forms an emission window and a reception
1. An optical measuring device, comprising: a housing, in which at least one optical emitter for emitting at least one emission beam and at least one optical receiver for receiving a reception beam are arranged,wherein a cover disc terminates the housing and forms an emission window and a reception window, wherein the at least one emission beam exits from the housing through the emission window,wherein the optical receiver receives the emission beam, which is reflected from the surroundings, as a reception beam through the reception window, andwherein the cover disc has a heating assembly arranged essentially in the region of the reception window with the region of the emission window being left out. 2. The device according to claim 1, wherein the heating assembly has at least one electrical heating conductor, which is applied to an elastic carrier. 3. The device according to claim 2, wherein the elastic carrier is embodied as a film, on which the at least one electrical heating conductor is applied as a metallization. 4. The device according to claim 1, wherein the heating assembly is one of arranged on an external surface, arranged on an internal surface of the reception window, and is integrated in the reception window. 5. The device according to claim 4, wherein the at least one electrical heating conductor extends directly on the reception window and touches the reception window on at least one touch region. 6. The device according to claim 4, wherein the at least one electrical heating conductor extends in the reception window essentially horizontally in parallel to a vehicle transverse axis. 7. The device according to claim 4, wherein the at least one electrical heating conductor extends vertically, in parallel to a vehicle vertical axis, on an edge region of the reception window and can be electrically contacted via at least one contact region. 8. The device according to claim 4, wherein the at least one electrical heating conductor is arranged in a meandering form on the carrier. 9. A method for producing a cover disc for a housing of an optical measuring device, wherein the cover disc comprises an emission window, a reception window, and a heating assembly having at least one electrical heating conductor, the method comprising: laying the heating assembly in a tool mould so that the at least one electrical heating conductor of the heating assembly is arranged after an injection-moulding operation in the region of the reception window and the region of the emission window is left out by the at least one electrical heating conductor of the heating assembly. 10. The method according to claim 9, wherein, during the injection-moulding operation, the heating assembly is connected to an external surface and/or an internal surface of the reception window and/or integrated in the reception window.
