The UV laser used for plastic switch laser engraving is not easy to be erased

In the old days, there were no marked buttons on the switch panel. We would find stickers or handwriting on the surface, which one is "on the light" or "off the light". This method is neither beautiful nor durable. However, since the popularization and application of ultraviolet laser technology in plastic switch panels marking LOGO, "light on", "light off", "exhaust fan", "bedside lamp" and other signs, the switch panel is no longer monotonous, and UV marking is not easy to be wiped. Besides, it also has a good anti-counterfeiting effect, eliminates counterfeit products and eliminates potential safety hazards.

The UV laser beam has no attenuation, the beam spot is uniform and compact, fast, good in light transmission, and fine marking. The coding effect is beautiful and exquisite, low-carbon and energy-saving, long life, easy to operate, especially suitable for assembly line marking on switch panels.

For 13 years of Seiko, for the switch panel marking processing industry, the Expert III 355 series of UV diode pumped pulsed solid-state lasers developed and produced by RFH have a power range of 10W-15W, using a unique laser cavity design, acousto-optic Q-switching technology, and high precision The cooling system, small size, and high integration have established an excellent brand image in the field of switch panel carving.

Expert III 355 high-power ultraviolet laser has a short pulse width (<20ns@40k), so during processing, the heat-affected area is small, and it is not prone to scorching and deformation; it is strictly guaranteed in all frequency ranges. Beam quality (M²<1.2) and perfect spot characteristics (spot ellipticity>90%); The inner cavity has a self-purification system, which makes the laser long life and stable operation; RFH design and production of UV lasers are controlled by a fully digital intelligent power supply Technology, simple operation, convenient monitoring, also supports communication with the computer, and can control the laser externally through RS232; integrated design, convenient equipment integration.

As we all know, there is a one-to-one correspondence between the power supply and the laser, and the stability of the power supply control system determines whether the laser can maximize its performance during operation. RFH has the advantage of independent research and development of laser dedicated power control system, which can update the power control system functional modules in time, and improve the functional modules according to laser requirements. This is also one of the reasons to ensure high power stability and long life of RFH lasers.

13 years of development and precipitation, RFH research and development, each laser product produced can maintain consistent stable quality, constant beam quality, high-efficiency power consumption under extreme industrial and scientific research conditions, with excellent cost performance and high reliability. It has won high recognition and a good reputation from users in all walks of life at home and abroad.
