Ruicheng Optoelectronics teaches you how to choose fiber laser marking field mirror lens
1. The field lenses produced by Ruicheng Optoelectronics in laser marking machines commonly include 70 * 70, 110 * 110, 150 * 150, 200 * 200, 220 * 220, 300 * 300, 500 * 500, etc. How to use different lenses is actually how to choose different focal lengths, which is mainly determined by several factors: the specific size of the marked object; The size of the marking range required; The level of precision required for processing and the overall matching of the equipment.
2. Focal length is related to the working distance to some extent. But the focal length does not equal the working distance. When the object is relatively large and the marking range is increased, the required lens is also relatively large. Manufacturers usually like to scan and mark a large range. Ruicheng kindly reminds you that simply increasing the scanning area can lead to many problems. That is to say, when the scanning area reaches a certain degree, the diameter of the obtained light spot is very large, the focus is not fine enough, the light spot becomes larger, the distortion increases, the power density of the laser decreases quickly, and the working distance is extended, which inevitably leads to the loss of laser energy. Not conducive to precision machining.
3. In addition, when choosing the focal length, you also need to consider the overall configuration of your device. If your device is a laser marking machine or a 10W fiber marking machine, it is recommended that the lens should not exceed a scanning range of 300 * 300. The larger the scanning range of the laser lens, the greater the consumption of the laser, and the poor quality of the beam will result in a decrease in the marking effect. Select the appropriate scanning range field mirror according to the power of the laser marking machine. Ruicheng Optoelectronics produces laser marking airport mirrors with various scanning ranges to help you match suitable products. For details, please contact the relevant technical personnel. We will serve you wholeheartedly!
