What laser light source is used for n95 mask laser marking
For N95 mask laser marking, a cold light source of ultraviolet laser is required
High-precision UV laser marking mask packaging
RFH Technology Epidemic Prevention: High-precision UV lasers are used to mark the outer packaging of masks with high speed, high precision and high stability.
This is a critical period for epidemic prevention. Less contact, frequent hand washing, and wearing masks are still indispensable for epidemic prevention. However, there is a huge demand for N95 masks and other protective products, and a hard-to-find dilemma has emerged across the country and the world. What is even more sad is that some illegal traders took advantage of the virtual reality to produce and sell fake masks.
Experts pointed out that fake masks not only cannot filter viruses, but may also cause adverse reactions such as allergies due to material problems, which seriously damage the health and interests of consumers. As a member of the laser industry, RFH believes that technology should be used to make some contributions to epidemic prevention.
Therefore, the RFH high-precision ultraviolet laser has become a powerful tool for marking information such as the production date and batch number of the N95 mask outer packaging, giving the authentic mask the traceability function.
The outer packaging of the mask is a disposable plastic film, which is not heat resistant and requires high laser light sources. The "cold" and "stable" characteristics of RFH high-precision ultraviolet lasers just meet.
RFH's Expert Ⅱ 355nm series ultraviolet laser, spot ellipticity >90%, pulse width <20ns@30k, heat-affected area is very small, beam quality M2<1.2 is strictly guaranteed in all frequency ranges, so it is on the outer packaging of plastic masks When marking the production date and other information, the material will not be burnt, the quality is guaranteed, and the speed is very fast, especially suitable for high-speed assembly line production of several masks per second.
At the same time, RFH's Expert Ⅱ 355nm series ultraviolet laser is integrated design, which is convenient for equipment integration; has an internal cavity self-purification system, which makes the laser long life and stable operation; has a unique Q-switching control technology, suitable for laser control of various types of masks demand.
With technology, the production of masks should be urgent. RFH laser has been on the way to contribute to society.
With 12 years of ingenuity, RFH Laser currently has a laser research and development team composed of professors, experts and doctors at home and abroad. It has set up application process research and development department, laser research and development department, electrical research and development department, 10 national patent certificates, and 14 computer software copyrights. Certificate, won the title of "High-tech Enterprise" and "Shenzhen High-tech Enterprise", and passed the provincial and ministerial technical appraisal and quality inspection approval. The ultraviolet laser series produced by the company have stable power, high integration, small size and long life. , Excellent beam quality, high stability, can be customized according to user needs and other outstanding advantages.
Each laser product developed and produced by RFH can maintain consistent and stable quality, constant beam quality, and high-efficiency power consumption under extreme conditions of industry and scientific research. With its superior cost performance and high reliability, it has won all walks of life at home and abroad. Industry users are highly recognized and have a good reputation. After 12 years of hard work, we have established an excellent brand image in the nanosecond laser industry.
