Nanosecond solid ultraviolet lasers mark black on PC clear plastics   It turned out that the effect of hacking in PC transparent plastic was achieved with RFH ultraviolet laser   PC is a polycarbonate plastic. It is a safe and non -toxic plastic material, but it is very prone to fake and shoddy plastic materials. Therefore, in many manufacturers, how to find the method of not affecting the performance and the authenticity of authenticity is very. important.   RFH nanosecond solid ultraviolet laser adopts a new integrated design. Strict double -layer sealing protection can operate in high temperature and high humidity environments, ensuring the life of laser in different environments.
