Document Type and Number:
Japanese Patent JP7382504
Kind Code:
B2
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 |α| 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, 40.1) up to the nth microlens (30n, 40n), wherein an optical wedge (5) is arranged behind the second microlens array (4) in the beam propagation direction and the focal lengths of the microlenses (30.1-30.n, 40.1-40.n) of the microlens arrays (3, 4) are selected such that a focal plane (6) of the device (1.1-1.m) lies in an air gap (7) between the second microlens array (4) and the optical wedge (5).
