Redshift UV laser – What is UV Laser?
To produce a UV laser, the laser beam passes through two additional crystals that conventional fibre laser systems lack. First, By passing a standard wavelength laser (1064 nm) through a nonlinear crystal, the wavelength is reduced to 532 nm. Then, this light is further passed through another crystal, effectively reducing its wavelength to 355 nm. As a result, UV lasers are commonly called third-harmonic generation (THG) lasers because they are the third wavelength created. Marking using these lasers is called “Cold Marking”, which refers to how they can perform marking and processing with minimal heat stress.
UV laser marker breaks the bonds directly instead of ruining the base material like many other laser markers. This process is known as “cold marking” because of the minimal heat stress. Cold marking is effective for high contrast and damage-free marking.
Because of the high absorption rate of UV lasers, there are plenty of materials that can be marked by a UV laser. absorption rate is incredibly high for a variety of materials.
Absorption Rate for Plastics
Absorption Rate for Metals
Redshift UV Laser Marking Feature: Damage-Free Marking & Processing , High-Contrast Marking
With high contrast, this robustness provides the characteristics, including resistance against ambient light, that enable marking operation with fewer failures.
This allows marking and processing to be performed with minimal heat stress. It also reduces surface damage, allowing for corrosion-resistant marking. These attributes protect the materials or components from issues during the marking and manufacturing process. This is true even for highly reflective materials like gold, silver, and copper and sensitive materials like glass, rubber, ceramic, and plastic.
Redshift UV Laser Damage-Free Marking Application: gold, silver, and copper and sensitive materials like glass, rubber, ceramic, and plastic, electronic parts, etc.
