Abstract

The invention provides an internal-focusing high power focusing lens, relates to the focusing lens and aims to solve the problems that an existing high-power laser large-aperture focusing lens fails to move precisely, precise focusing is unavailable, and multiple beams of high-energy lasers are difficult to focus to a minimal cross section in space. The internal-focusing high power focusing lens comprises a lens shielding sheet assembly, a lens replacing unit assembly, an X-direction position adjusting assembly, a Y-direction position adjusting assembly and a Z-direction position adjusting assembly. The lens shielding sheet assembly is installed on the lens replacing unit assembly. The lens replacing unit assembly is installed on the X-direction position adjusting assembly. The X-direction position adjusting assembly is used for driving a lens driving assembly to move in the X direction. The X-direction position adjusting assembly is installed on the Y-direction position adjusting assembly. The Y-direction position adjusting assembly is used for driving the X-direction position adjusting assembly to move in the Y direction. The Y-direction position adjusting assembly is installed on the Z-direction position adjusting assembly. The internal-focusing high power focusing lens is suitable for focusing the 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...
