Description

technical field

[0001] The invention relates to the field of optical equipment, in particular to a telecentric laser field lens and a laser scanning system thereof. Background technique

[0002] In the process of modern industrial manufacturing, laser processing is widely used in welding, surface treatment, drilling, marking and other processing technologies due to its advantages of high precision and high efficiency; laser processing is mainly composed of four parts, namely Laser, power supply, optical system and mechanical system; the optical system generally includes X / Y galvanometer and scanning field lens; the scanning field lens is generally installed at the end of the laser system to form a focal plane, and by controlling the X / Y galvanometer Reflection angle, so that the laser beam is focused on different areas of the focal plane, so as to achieve marking, welding, laser cleaning, 3D printing and other processes; scanning field mirrors are generally divided into: fla...
