Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0016] Such as figure 1 As shown, a simple homogenization device includes a beam splitting device, a focusing lens 4 and a collimating lens 5. The beam splitting device divides the incident laser light into several beams of equal intensity laser beams, and the focusing lens 4 focuses the laser beams of several beams of equal intensity. The beams are combined into one laser beam, and the collimating lens 5 adjusts the overlapping ratio of the combined laser beams to form a uniformly distributed laser beam in the central area.

[0017] The beam splitting device is used to divide the incident laser light into four equal-intensity laser beams, and the four equal-intensity laser beams are incident o...

Abstract

The invention discloses a simple light homogenizing device, which comprises a light splitting device, a focusing lens and a collimating lens, wherein the light splitting device divides the incident laser into a plurality of laser beams of equal intensity, the focusing lens focuses and combines the plurality of laser beams of equal intensity into a laser, and the collimating lens adjusts the overlapping ratio of the combined laser beams to form laser beams uniformly distributed in the central region. The device continuously splits the incident laser by the light splitting device and finally synthesizes a laser beam uniformly distributed in the central region, has a compact and simple structure, improves the utilization of the light energy, and is easily added to various types of optical paths.

Description

technical field [0001] The invention relates to a simple uniform light device, which belongs to the field of laser technology. Background technique [0002] Due to its good directionality and high brightness, laser beams are widely used in many aspects such as laser lighting, laser display, and laser processing. However, since the power distribution of the laser itself is a Gaussian distribution, the uneven distribution of power causes various problems in the application process, such as the problem of center burn-through during laser processing. In order to obtain a uniformly distributed light field, it is usually necessary to design a complex optical system, which has a complex structure and is not easy to insert into the original optical path of the laser. Contents of the invention [0003] The invention provides a simple uniform light device, which solves the problem that the structure of the traditional optical system is complicated and it is difficult to insert into...
