Laser Coding Applications
The most significant difference between fiber optic, CO2, and UV laser encoders is the wavelength of the light they produce. Shorter wavelengths typically have more energy and higher absorption than longer wavelengths. Therefore, a laser's wavelength affects its ability to mark specific materials.
FIBER Laser
Fiber lasers have a wavelength of 1064nm and are therefore infrared (IR) lasers. Fiber lasers can mark a wide variety of materials and are particularly suitable for marking items made of metal.
CO2 Laser
CO2 lasers are suitable for transparent materials such as paper, resin, wood, rubber, glass, and PET because they have a wavelength 10 times longer than standard wavelength systems.
UV Laser
UV lasers utilize a highly absorbable wavelength (355nm). Therefore, UV lasers are ideal for applications requiring high contrast or minimal product damage.
