Abstract

The invention relates to an optical lens and a laser machining device with the optical lens. The optical lens comprises a first lens body, a second lens body, a third lens body and a fourth lens body which are sequentially distributed in the transmission direction of incident light beams. The first lens body is a double-concave negative lens, the second lens body is a meniscus positive lens, the third lens body is a flat-convex positive lens, and the fourth lens body is a double-convex positive lens. Substrates of the first lens body, the second lens body, the third lens body and the fourth lens body are made of high-temperature-resistant optical materials. According to the optical lens and the laser machining device with the optical lens, the substrates of the first lens body, the second lens body, the third lens body and the fourth lens body are made of the high-temperature-resistant optical materials, so the optical lens is applicable to the continuous high-power ultraviolet laser work environment, accordingly the problem that ultraviolet laser causes deformation of lens bodies in a lens can be effectively avoided, and fineness and definition of ultraviolet laser during workpiece machining are guaranteed.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to an optical lens and laser processing equipment with the optical lens. Background technique [0002] Due to the short wavelength of the ultraviolet laser and the small radius of the focused spot, and the small diffuse spot and high resolution of the ultraviolet laser, the ultraviolet laser can be finely processed, so it is widely used in the processing of products. [0003] However, due to the short wavelength of the ultraviolet laser, the energy carried by the ultraviolet laser is larger than other types of lasers under the same power, which easily causes the lens in the lens to deform. For example, UV lasers change the radius of curvature of the lens, which affects the focal length of the entire lens. Especially when the lens is used in a continuous high-power ultraviolet laser working environment, some areas in the center of the lens will be continuously irradiated by...
