Abstract
An optical device for modifying a light beam has a first stop for delimiting the light beam in a first plane, a second stop for delimiting the light beam in a second plane aligned at a predefined non-zero angle, in particular perpendicularly, to the first plane, and a zoom unit for modifying the extent of the light beam, the zoom unit having comprising at least one fixed lens and at least two, in particular at least three, lenses that are movable relative to the fixed lens along a first axis.
Claims15
An optical device for modifying a light beam, the optical device comprising:
- a first stop for delimiting the light beam in a first plane,
- a second stop for delimiting the light beam in a second plane aligned at a predefined non-zero angle to the first plane,
- and
- a zoom unit for modifying the extent of the light beam, the zoom unit comprising at least one fixed lens and at least two lenses that are movable relative to the fixed lens along a first axis.
A method for generating a modified light beam, the method comprising:
- generating a light beam;
- guiding the light beam through a first stop for delimiting the light beam in a first plane;
- guiding the light beam through a second stop for delimiting the light beam in a second plane aligned at a predefined non-zero angle to the first plane;
- and
- guiding the light beam through a zoom unit for modifying the extent of the light beam, the zoom unit comprising at least one fixed lens and at least two lenses that are movable relative to the fixed lens along a first axis.
