1. Powell lense-Laser processing and industrial manufacturing
1.1 Laser cutting and welding
In modern industrial manufacturing, laser cutting and welding technology is widely used because of its high efficiency and precision. The emergence of Powell lense has brought revolutionary changes to this field. Its unique beam shaping ability enables the laser beam to be effectively converted into a uniform line laser. This conversion not only improves the quality of processing, but also ensures the consistency and reliability of the processing process.
Application: Powell lense can convert Gaussian beam into uniform line laser, which is crucial for laser cutting and welding processes. This uniformity enables the laser to be evenly distributed on the surface of the material, thus avoiding the problem of uneven cutting edges caused by uneven beams.
Advantages: Laser cutting systems using Powell lenses can achieve more than 90% intensity uniformity, which is a significant advantage in many industrial applications. In addition, Powell lens supports laser power up to 500W, which is particularly suitable for lasers using materials such as ZnSe. This high power support enables lasers to complete tasks with higher efficiency and precision in cutting and welding of thick materials.
1.2 Laser Marking
Laser marking technology plays an important role in product identification, traceability and brand protection. The application of Powell lenses in this field significantly improves the accuracy and efficiency of laser marking.
Application: Powell lenses can generate high-precision line points, which is particularly important for applications such as battery labels that require strict control of line width. By converting laser beams into uniform line lasers, Powell lenses ensure the clarity and consistency of each mark.
