Abstract

An adjustable focus high-power focusing lens, which relates to a focusing lens to solve the problem that the large-aperture focusing lens of the existing high-power laser cannot be moved accurately, and cannot achieve precise focusing and focus multiple beams of high-energy lasers on a small section of space There is a difficult problem in memory, which includes the lens shield assembly, lens replacement unit assembly, X-position adjustment assembly, Y-position adjustment assembly, and Z-position adjustment assembly; the lens shield assembly is installed on the lens replacement unit assembly, and the lens replacement The unit assembly is installed on the X-direction position adjustment assembly, the X-direction position adjustment assembly is used to drive the lens drive assembly to move in the X direction, the X-direction position adjustment assembly is installed on the Y-direction position adjustment assembly, and the Y-direction position adjustment assembly is used for In order to drive the X-direction position adjustment component to move in the Y direction, the Y-direction position adjustment component is installed on the Z-direction position adjustment component. The invention is used for focusing of a focusing lens.

Description

technical field [0001] The invention relates to a focusing lens and belongs to the field of optical lens adjustment devices. Background technique [0002] Focusing lens engineering is widely used, such as various laser processing, laser inspection, etc. Most of the equipment can also achieve focusing or even automatic focusing. However, the large-aperture focusing lenses currently used for high-power (million-joule) lasers cannot achieve precise focusing in the three directions of the X-axis, Y-axis, and Z-axis. difficulty. Contents of the invention [0003] The present invention aims to solve the problems that the large-diameter focusing lens of the existing high-power laser cannot be moved accurately, cannot achieve precise focusing and the difficulty exists in focusing multiple high-energy laser beams into a small section of space, and further provides an adjustable focus high Power focus lens. [0004] The technical solution adopted by the present invention to solve...
