UV laser featuring cold processing for marking plastic button on keyboard More and more manufacturers choose UV laser marking machine to create pattern and characters on the plastic button switch. The focal spot of UV laser is pretty small with little heat transfer to surrounding material, so UV laser is also called “cold light source”. Because of this feature, heat effect won’t occur. Thus, distorting or burning of materials is no longer an issue.    Professional UV laser manufacturer - Shenzhen RFH Laser Technology Co.,Ltd    With 13 years of experience, the S9 series nanosecond UV laser developed and produced by RFH can engrave clear characters on the keyboard and the mouse. These kinds of characters can not only help people identify different buttons in the dark but also last long, for there are slightly protruding part on the buttons. This improves the durability and practicability of the keyboard and the mouse.   

3W 5W UV laser source for SLA 3D printing Early this month, Jason, who is the boss of 3D model producer, asked about what kind of laser is suitable for Photopolymer SLA process and we recommended S9 series UV laser.  RFH 355 series UV laser features high efficiency, stable laser output and compact design, making it the suitable laser for Photopolymer SLA process. This UV laser has a laser wavelength at 354.7nm with repetition rate up to 200kHz. Its laser power ranges from 3w to 10w absolutely assured in all repetition rates. Besides, it is characterized by exceptional beam quality (M²<1.2) ,relatively short pulse width <12ns@30k with little heat transfer to surrounding material during the marking process.   In addition, this UV laser is designed with unique Q-switching technology and supports communication with computer. RS232 control interface ensures easy control of the laser from the outside, which reduces the labor cost to a large extent. Such an easy-to-use, easy-to-install and compact laser can meet the different needs of Photopolymer SLA process.
