Method for processing a sensor, and sensor

A method for processing a sensor, wherein the sensor has a sensing element arranged in a housing, the housing having an opening, wherein a gel covering the sensing element is arranged inside the housing, the method comprising:

• applying laser radiation through the housing opening to a gel surface of the gel facing away from the sensing element, such that the gel surface is modified by the applied laser radiation,
• wherein the sensor and the laser radiation are moved relative to each other during the application of laser radiation to the gel surface based on a specified target relative movement.

A sensor, comprising:

• a sensing element arranged in a housing, wherein the housing has a housing opening, wherein a gel covering the sensing element is arranged inside the housing,
• wherein the gel has a gel surface facing away from the sensing element and modified by laser radiation,
• wherein the modification includes a ring structure having a plurality of concentric rings, and/or line structure having a plurality of parallel lines.
