355nm Ultraviolet (UV) Laser Modules, as a cold processing tool, can easily handle the processing of fragile materials such as curved glass and crystal. It has narrow pulse width and concentrated energy, which can directly destroy the chemical bonds of substances without heating, and is convenient and quick to operate, and is environmentally friendly. Therefore, it is an ideal tool for processing fragile materials. It can be used for marking, etching, engraving, etc. on the glass, and its application is very popular and extensive. Through computer operation and control, it can be precisely processed according to the design, and the pattern can be from millimeter to micron, so the anti-counterfeiting is good, the pattern is clear, neat and beautiful, and the traditional process cannot be compared with it.

The following is an example of RFH ultraviolet laser blackening on the surface of ceramics. The text is clear, the color difference is obvious, and the efficiency is extremely high. Use RFH UV laser marking, which belongs to non-contact processing, which can ensure processing accuracy.

The well-known function of RFH high power uv laser is marking on plastics. In addition to this outstanding technology, RFH high power uv laser can also perform glass engraving, PCB circuit board engraving and cutting, SLA 3D printing, etc. Production. RFH high power uv laser is produced by emitting 355nm high power uv laser to scratch on the surface of the material.

Plastic sockets generally mark the brand logo on the outside, and mark the QR code on the inside. Due to the structure of the plastic socket, the size of the QR code and the logo is small, which weakens the effect of the traditional marking device. RFH 3w-5w UV laser is a laser that can replace traditional markers and greatly improve the quality of socket marking.

Laser marking on plastic or laser engraving on plastic is a process by which components are labeled or marked with the aid of a laser.

3w uv laser marking qr code on white plastic. Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved

High-power uv laser marking ceramic   Expert III 355 series UV DPSS laser, developed and produced by RFH, covers 10w-15w in laser power with short pulse width (<20ns@40K) ,superior beam quality (M²<1.2) and perfect laser spot quality (beam circularity >90%). It is widely used in PE/PCB/FPC cutting, glass & sapphire cutting, drilling, scribing & cutting used in high precision micromaching areas.

3w 5w uv laser for marking/engraving the back side of glass substrates 355 nm output wavelength, Up to 200 Hz repetition rate; laser power ranging from 3w-10w; Continuous tuning of repetition rate while maintaining constant pulse energy, superior beam pointing and energy stability make the S9 the first choice for micromachining, marking and thin film removal applications   

Laser processing on glass Marking and Laser Engraving on Glass Glass is a complex material to be processed due to its characteristics of fragility and poor heat transfer. Over the years these challenges have been faced and solved using specific laser technologies, suitable for this difficult task.

3w 5w uv laser source engraving “marking” of select coated and uncoated glass Laser etched graphics, icons and unique identifiers (QR codes and barcodes) These two methods of laser engraving and etching add to the company’s Total Solution approach of single-point accountability for fabricated specialty glass components.

355nm UV Laser marking makes it easy to identify parts and authenticity without a physical tool etching the surface of the part or transmitting any substances onto the surface. Instead, the laser light is focused onto a material, producing damage-free, easy-to-read marks. Apple Rubber uses laser marking to add model numbers, bar codes, logos and more onto customer’s o-rings and seals.
