Claims (4)

1. Vorrichtung zum Beschriften oder Markieren eines Gegenstandes, dessen zu beschriftende oder markierende Fläche aus Kunststoff besteht, der strahlungs­ sensitive Pigmente aufweist, die bei Auftreten von Laserlicht mit ausreichender Energiestromdichte einen Farbumschlag im Kunststoff bewirken, mit
  • - einem CO2-Laser (10)
  • - einem Ablenkspiegel (14) zur Ablenkung des von einer Optik fokussierten Strahls (12) des CO2-Lasers (10)
  • - einer von einer Steuervorrichtung (22) gesteuerten Antriebsvorrichtung (16) für den Ablenkspiegel (14)
  • - und einer Pulssteuervorrichtung (24) für den CO2-Laser (10) zur Abgabe von Laserpulsen (26), von denen jeder ausreicht, einen Farbumschlag zu bewirken.
1. Device for labeling or marking an object, the surface to be labeled or marked consists of plastic, which has radiation-sensitive pigments which cause a color change in the plastic when laser light occurs with sufficient energy current density
  • - a CO 2 laser ( 10 )
  • - A deflection mirror ( 14 ) for deflecting the beam ( 12 ) of the CO 2 laser ( 10 ) focused by optics
  • - One of a control device ( 22 ) controlled drive device ( 16 ) for the deflecting mirror ( 14 )
  • - And a pulse control device ( 24 ) for the CO 2 laser ( 10 ) for delivering laser pulses ( 26 ), each of which is sufficient to cause a color change.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Pulsbreite der Laserquelle (10) einige Mikrosekunden beträgt.2. Device according to claim 1, characterized in that the pulse width of the laser source ( 10 ) is a few microseconds. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Pulsbreite etwa 10 bis 20% des Pulsabstands beträgt. 3. Device according to claim 1 or 2, characterized in that the pulse width is about 10 to 20% of the pulse interval.   4. Vorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Pulshöhe etwa das Dreifache der Dauerleistung des CO2-Lasers (10) beträgt.4. Device according to one of claims 1 to 3, characterized in that the pulse height is approximately three times the continuous power of the CO 2 laser ( 10 ).
