Claims11
An optical head for a device for laser transmission welding, the optical head comprising:
- a housing with an end on an outlet side with respect to a laser beam;
- a ball mounted in the housing, wherein the ball is made of a material whose refractive index is at least 1.45;
- an air bearing for mounting the ball associated with the housing, the air bearing comprising an opening for the passage of the laser beam, wherein the opening measures a maximum of 4 mm in diameter;
- and
- a converging lens designed and/or arranged within the housing such that a focal point of the laser beam is located between the converging lens and the ball,
- wherein the converging lens is arranged in the optical head such that there are no optical elements positioned along an optical axis of the laser beam between the converging lens and the ball.
