Title:
OPTICAL SYSTEM AND LASER WELDING DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/221322
Kind Code:
A1
Abstract:
An optical system and a laser welding device thereof. The optical system sequentially comprises, along an optical axis, a collimating lens (2), comprising a first incident lens surface (21) and a first emergent lens surface (22), one of the first incident lens surface (21) and the first emergent lens surface (22) being a plane while the other being a convex surface; a focusing lens (3), comprising a second incident lens surface (31) and a second emergent lens surface (32), one of the second incident lens surface (31) and the second emergent lens surface (32) being a plane while the other being a convex surface. Included angles being larger than 0° are formed between the connecting lines between the vertexes of the convex surfaces and the circle centers of the curvature radiuses at the vertexes of the collimating lens (2) and the focusing lens (3) and the normal lines of the planes of the collimating lens (2) and the focusing lens (3). The collimating lens (2) and the focusing lens (3) can rotate by taking the optical axis as a rotating axis.
