Abstract

The present disclosure provides a combined polyhedral prism, which includes: N optical elements, the N optical elements can cooperate to form the combined polyhedral prism; each optical element includes a first abutting surface, a second abutting surface surface, incident surface and exit surface; wherein, the first abutting surface and the second abutting surface are both located between the incident surface and the exit surface; passing through the first abutting surface of adjacent optical elements among the N optical elements The contacting and separation of the abutting surface and the second abutting surface enables the N optical elements to be set to abut against each other and to be completely separated from each other. When the N optical elements are set to abut against each other, The incident light beam passes through the incident surface and the exit surface of each optical element to form independent N focal points; when the N optical elements are set to be completely separated from each other, the incident light beam does not pass through the optical element to form a focal point. The present disclosure also provides a beam splitting device.

Description

technical field [0001] The disclosure relates to a combined polyhedron prism and a beam splitting device, belonging to the field of lasers. Background technique [0002] In the field of laser processing, different occasions have different requirements for the beam and intensity of the laser. For example, in some occasions, the laser beam needs to be focused to one point, so that the energy of the focus is higher, and in some occasions, the laser beam needs to be focused into multiple points. , to meet different purposes. [0003] Chinese invention patent document CN108845409A discloses a device and method for generating array multi-focus points based on a polyhedral prism, which can split laser beams through a polyhedral prism to form multiple focal points. However, the device cannot form a focal point and cannot be applied to multiple occasions. [0004] The Chinese invention patent document CN101126823A discloses an isosceles trapezoidal color-combining combined prism fo...
