Device for measuring the surface temperature of an object, a system for controlling the engraving parameters of a laser using this device and related method (Google link)

The invention relates to a device (100) for measuring a surface temperature of an object (OB), the device (100) comprising:

  • a base (10) including a main face (11), defining a plane ( XY), is provided with a marking (12);
  • a wall (20) mounted on said base (10) and one face (F) of which defines a plane (YZ) perpendicular to the main face (11) of the base (10);
  • an infrared thermometer (30) comprising a sighting axis (AV) and mounted on the wall (20) so that, in a plane (P) which is on the one hand both perpendicular to said main face (11) of the base (10) and to said face (F) of the wall (20) and which also comprises said sighting axis (AV), the angle (α) formed between said sighting axis (AV) and the face (F) of the wall (20) is arranged so that said sighting axis (AV) passes through the marking (12) of the main face (11) of the base (10).

The invention also relates to a system for controlling the engraving parameters of a laser using the device, as well as a related method.
