The difference between ultraviolet and infrared laser marking machine

 

What we are talking about for purple light is a UV laser marking machine with a wavelength of 355 or 266, and what we are talking about for red light is a fiber laser marking machine with a wavelength of 1064. Purple light and red light are not only different in wavelength, but also in other places.

 

UV laser marking machine:

 

The ultraviolet laser used in the laser has a shorter wavelength of 266nm or 355nm, and the beam quality is relatively good in several types of laser beams. The energy of a single photon is relatively large. Use this to break the chemical reaction between the material molecules and the material to form a sculpture. This technology is a cold processing technology. It is less affected by heat and does not produce too much thermal response to processed products. The processing line width is generally thinner between 10μm. The characteristics of the purple light itself, high energy can directly destroy the surface molecular health of many non-metallic materials, and the parts processed by cold light treatment technology are smooth. Moreover, the superiority of purple light can be focused on points on the order of sub-micron level, so it can be processed for small parts. Even at low pulse energy levels, it can also obtain high energy density and effectively process materials.

 

Infrared laser marking machine:

 

The wavelength of the red laser marking machine is 1064 microns. In the material processing, the heat of the strong light and high-density light and the material itself are generally subjected to physical and chemical reactions to achieve the purpose of marking. Many plastic markings will have a great thermal reaction when encountering strong heat, causing scorching, etc. The effect of marking is not obvious. Metal products will be less affected by heat when burned with strong light, the markings are clear, and the speed is relatively speaking Also faster. The beam quality is relatively general, and the single-photon quality is relatively small. Because some products do not absorb red light, there is no response to the processing of some products, and it has no effect.

자주색 빛과 붉은 빛의 제품에 표시는 일반적으로 제품과 화학적으로 반응합니다. 파장 빔의 품질, 단일 광자의 에너지 및 처리 원리가 다르기 때문에 보라색 처리는 냉간 처리 기술에 속하고 적색 처리는 열간 처리 기술에 속합니다. 제품의 적색광 부분은 다른 이유로 흡수되지 않으며 두 가지 유형의 기계는 제품 재료 마킹 범위가 제한되어 있습니다.
