UV laser has a wavelength of 355nm and features short pulse width, high quality laser beam, high precision and high peak power. These outstanding features make UV laser the ideal laser source in laser marking. UV laser doesn’t has the same wide applications in material processing as infrared laser (wavelength is 1.06μm), but it is excellent in processing plastics and some special polymers that are used as the base materials in PCB and these kinds of materials can not be processed by infrared laser or heat treatment.
Therefore, comparing with infrared laser, UV laser has smaller heat effect and in nano-level and micro-level high precision processing materials that are quite sensitive to heat effect, UV laser has obvious advantages.
Laser marking uses high energy density laser light to project on the item surface so that the item surface will evaporate or change color, leaving a permanent marking. Since UV laser has the above-mentioned features, it is often used as the laser source of laser marking machine. The computer keyboard which is very common in our daily life, is processed by UV laser marking machine. In the past, computer keyboard uses inkjet printing to produce the letters, but as time goes by, the letters begin to fade away, which is very unfriendly to the users. But with UV laser marking machine, the letters on the keyboard will remain the same no matter what. In fact, the markings (characters, symbols, patterns, etc.) produced by UV laser marking machine can be nano-level or micro-level, which is very precise and very helpful in anti-counterfeiting.
Just like any other kinds of precision instruments, UV laser also needs to be properly cooled to maintain its precision. And you need an efficient water chiller system. S&A Teyu CWUP series portable chiller units could be your ideal options. This series of water chiller system features high temperature stability of ±0.1℃ and Modbus-485 capable so that communication between the UV laser and the chiller can be realized. This kind of high temperature stability guarantees the UV laser is always under consistent temperature range. Plus, CWUP series portable chiller units are equipped with caster wheels, so you can put it anywhere you want.
