How to choose laser welding protective lenses? Today, with the increasing application of laser welding equipment, many enterprises already have a large number of laser welding machines, such as laser welding machines, laser marking machines, and laser cutting machines. The selection of some consumables during the use of laser welding equipment is directly related to the cost and product quality, such as xenon lamps, krypton lamps, protective lenses, and especially the loss of protective lenses. The main function of laser protection lens is to prevent dust and splash from damaging the focus lens. However, if the lens is not properly selected, it will cause large laser loss, frequent damage to the protection lens, unstable product quality, and serious losses to enterprises.
The principles for choosing laser welded protective lenses are as follows:
1. Matching of external dimensions
2. Material: Based on different laser powers and considering usage costs, K9 and quartz can be selected. In practical applications, professional manufacturers divide these two types of materials into multiple grades, and customers can choose corresponding specifications according to their actual needs
3. Coating, laser antireflection coating, using different coating technical parameters according to the usage environment. Nahong Optoelectronics adopts advanced optical coating process and can withstand up to 20000 laser power.
