What is the difference between UV laser machine and ordinary laser machine?
Now UV laser marking machine is the most common laser machine in the market,. it is a new type of marking machine which use the UV ray to finish the surface marking or coating. It still belongs to laser marking machine family. Compared to ordinary laser marking machine (infrared laser marking) it has some differences and similarities. Shenzhen Smida Electronics Co Ltd would like to give a brief summary about their differences: 1. Difference wavelength The wavelength of ordinary laser( infrared laser) is 625-740nm, while the UV wavelength is 380-440nm. From comparison of the wavelength, we can conclude that UV laser has higher marking speed and higher spread speed in the same medium. It is granted that people will prefer UV laser marking machine. 2. Different forms of light emission① The UV is generated by 808nm LD pump crystal , which means, it produces laser quite easy.② In ordinary laser, among the atom of composition material, there are a different number of electron...
