Abstract
An optical beam shaping unit for shaping a beam bundle. The optical beam shaping unit has at least one ball lens for shaping the beam bundle, wherein the ball lens allows a large portion of the light incident on the ball lens to pass through, and wherein the optical beam shaping unit has at least one optical unit which has a positive effective focal length and which is arranged in a beam path with the ball lens.
Claims10
An optical beam shaping unit for shaping a beam, the optical beam shaping unit comprising:
- at least one spherical lens for shaping the beam, wherein the spherical lens allows a major portion of light that is incident on the spherical lens to pass;
- at least one optical unit with a positive effective focal length, which is arranged in one beam path with the spherical lens;
- at least one light source for producing the beam;
- and
- a detector apparatus for detecting an incident beam,
- wherein the spherical lens and/or the optical unit are adapted to be displaceable in a z-direction with respect to a coordinate system xyz to set a divergence of the beam downstream of the optical unit,
- wherein the z-direction corresponds to a propagation direction of the beam, and
- wherein the at least one spherical lens is adapted to image the beam in the direction of the optical unit.
