Abstract

A device in the form of a sensor, including a housing having a surface which includes at least one subarea having a spectral emissivity which includes a first emissivity in a first wavelength range and a second emissivity in a second wavelength range, which is different from the first wavelength range, the first emissivity being smaller than the second emissivity and the ratio of the second emissivity to the first emissivity being at least 1.5.

First claim

What is claimed is:

1. A device, comprising:
a sensor;
wherein the sensor includes a housing having a surface which includes at least one subarea having a spectral emissivity which includes a first emissivity in a first wavelength range and a second emissivity in a second wavelength range, which is different from the first wavelength range, and wherein the first emissivity is smaller than the second emissivity and wherein a ratio of the second emissivity to the first emissivity is at least 1.5, and
wherein the housing includes in the at least one subarea, a metal, to which an arrangement of glass balls embedded in a polymer is applied.

2. The device as recited in claim 1 , wherein the ratio is at least 2, or at least 3, or at least 4.5, or at least 6.

3. The device as recited in claim 1 , wherein the first emissivity is smaller than 0.3, or smaller than 0.2, or smaller than 0.15.

4. The device as recited in claim 1 , wherein the second emissivity is greater than 0.75, or greater than 0.8, or greater than 0.9, or greater than 0.95.

5. The device as recited in claim 1 , wherein the first wavelength range is in a range from 0 nm to 5,000 nm, or from 300 nm to 2,500 nm, or from 400 nm to 1,200 nm.

6. The device as recited in claim 1 , wherein the second wavelength is in a range from 5,000 nm to 20,000 nm, or from 8,000 nm to 14,000 nm.

7. The device as recited in claim 1 , wherein the at least one subarea is orientable in parallel to the Earth's surface.

8. The device as recited in claim 1 , wherein: (i) the housing includes in the at least one subarea SiO 2 and HfO 2 , and/or (ii) an arrangement of glass balls embedded in a polymer, and a reflective silver layer is situated on the side of the polymer facing the inner surface of the device.

9. The device as recited in claim 8 , wherein the polymer is polymethylpentene.

10. The device as recited in claim 1 , wherein the polymer is polymethylpentene.

11. The device as recited in claim 1 , wherein the sensor is a LIDAR sensor.

12. A method for manufacturing a device including a sensor, comprising:
providing a housing for the device, the device including the sensor;
manufacturing a surface for the housing so that in at least one subarea, the housing has a spectral emissivity which includes a first emissivity in a first wavelength range and a second emissivity in a second wavelength range, which is different from the first wavelength range, wherein the first emissivity is smaller than the second emissivity and wherein the ratio of the second emissivity to the first emissivity is at least 1.5; and
providing the housing, in the at least one subarea, with a metal layer, to which an arrangement of glass balls embedded in a polymer is applied.

13. The method as recited in claim 12 , wherein the polymer is polymethylpentene.

14. A vehicle, comprising:
a device having a sensor;
wherein the sensor includes a housing having a surface which includes at least one subarea having a spectral emissivity which includes a first emissivity in a first wavelength range and a second emissivity in a second wavelength range, which is different from the first wavelength range, wherein the first emissivity is smaller than the second emissivity and wherein a ratio of the second emissivity to the first emissivity is at least 1.5, and
wherein the housing includes in the at least one subarea, a metal, to which an arrangement of glass balls embedded in a polymer is applied.
