The desktop UV laser marking machine is a compact, high-precision laser processing device designed specifically for desktop use. It employs UV laser technology with a short wavelength and concentrated energy, enabling precise marking on various materials such as plastics, glass, and metals. The machine is easy to operate, controlled by a computer, and can quickly generate text, patterns, QR codes, and other markings. It is widely used in industries like electronics, medical, and jewelry for product identification, anti-counterfeiting, and decoration. The desktop UV laser marking machine is space-saving, energy-efficient, and an ideal marking solution for modern industry.
Detailed Description of the Desktop UV Laser Marking Machine
1. Laser Source
The desktop UV laser marking machine employs a high-quality 355nm UV laser source. Its core technology is the third-harmonic intracavity frequency-doubling technique. This laser source features high beam quality and an extremely small focal spot, enabling ultra-fine marking effects. Compared to infrared lasers, the short wavelength of UV lasers means minimal thermal impact during processing, which is why it is referred to as “cold processing.” This makes it particularly suitable for processing heat-sensitive materials.
