Detailed Description

F-Theta lens, also known as scan lens, is a professional scan lens system, the purpose is to form a average spot of the laser beam in a certain marking field, it is one of the most important accessories of laser marking machine. The main indicators of the scan lens are scan field and focal length, normally, the scan field is related to the focal length, the longer focal length, the bigger scan field. But as the focal length increases, the diameter of the focused spot also increases correspondingly, which means when the scanning area reaches a certain level, the light spot diameter is large, which means that the marking spot is not fine enough, the power density decreases very fast. When Customers choose a scan lens, you have to consider the scan field and marking accuracy, to select the appropriate lens. The scan lens we provide, owns a better curvature ratio combination after many tests, so the marking spot is finer, the marking is more efficient and precision with the same focal length.
