Abstract: The invention relates to a device (1.1-1.m) for homogenizing laser light (2.1-2.m), comprising a first microlens array (3) comprising a plurality of microlenses (30.1-30.n) arranged side by side in a first direction and a second microlens array (4) comprising a plurality of microlenses (40.1-40.n) arranged side by side in the first direction; wherein the second microlens array (4) is arranged in the beam propagation direction of the laser light (2.1-2.m) from the first microlens array (3) and the plane (41) of the lens vertices of the second microlens array (4) is inclined at an angle |?| to the plane (31) of the lens vertices of the first microlens array (3), and wherein the microlens arrays (3, 4) are formed such that the focal lengths of the microlenses (30.1-30.n, 40.1-40.n) arranged side by side in the first direction change starting from the first microlens (30.1, 40.

Abstract: Device for generating a linear intensity distribution in a working plane (20), comprising at least one laser light source (11), optics (14) which shape the light (12) emitted by the at least one laser light source (11) in a first direction (X) and/or in a second direction (Y), a beam transformation device (13) increasing the beam quality factor (Mx2) with respect to the first direction (X) and decreasing the beam quality factor (My2) with respect to the second direction (Y), as well as an objective (17) acting in the second direction (Y) and a focusing device (18) acting in the second direction (Y), which is arranged behind the objective (17), wherein the objective (17) and the focusing device (18) image into the working plane (20) a plane (19) behind the beam transformation device (13) in which the light (12) in the second direction (Y) has an intensity distribution with a super-Gaussian profile or with a profile similar to a super-Gaussian profile.
