Abstract
An optical system for generating a 360° laser line includes a first cone optical unit, a second cone optical unit, and a third cone optical unit. The first cone optical unit is configured in a form of a first negative cone section with a first cone axis and has a conical first inner lateral surface with a first opening angle, a conical first outer lateral surface, and a first cone vertex. The second cone optical unit is configured in a form of a second negative cone section with a second cone axis and has a conical second inner lateral surface with a second opening angle and a second outer lateral surface. The third cone optical unit has a third cone axis, a cone shell with an opening angle, and a second cone vertex, where the opening angle of the cone shell differs from 90°.

- 62) with a first opening angle (2*β1), a conical first outer lateral surface (28;
- 63), and a first cone vertex (29;
- 64);
- a second cone optical unit (22;
- 53) which is configured in a form of a second negative cone section with a second cone axis (30;
- 65) and which has a conical second inner lateral surface (31;
- 66) with a second opening angle (2*β2) and a second outer lateral surface (32;
- 67);
- and
- a third cone optical unit (24;
- 54) which has a third cone axis (33;
- 68), a cone shell (35;
- 69) with an opening angle (2*α), and a second cone vertex (36;
- 70), wherein the opening angle (2*α) of the cone shell (35;
- 69) differs from 90°.
