Product description

F-Theta lens, also known as scanning lens, is used to form a uniform laser beam spot in a certain marking area. It is one of the most important accessories of laser marking machine.

The main indicators of the scanning lens are the scanning range and focal length. Generally, the longer the focal length, the larger the scanning field and the larger the diameter of the focal spot. This means that when the scanning area is large to a certain extent, the spot is not fine enough, and the laser power density will be insufficient.
