RFH 355nm UV Nanosecond Solid State Laser Marking Glassware Scale

In scientific research experiments in biology, medicine or chemistry, conical flasks, graduated cylinders, burettes, beakers, pipettes, pipettes, volumetric flasks and other graduated glassware are often used. In order to make the experimental results accurate and reliable and achieve the expected experimental results, in addition to requiring the glassware itself to be uniform in thickness and not deformed, it is very important to strictly require accurate and clear measurement scales, especially in the face of various acid and alkali liquids. After repeated washing and washing, the scale can be retained for a long time, and it is not easy to fall off and not blur.

The traditional scale method adopts the etching method and screen printing. The etching method is time-consuming, labor-intensive and low in accuracy, and has been eliminated. With screen printing, the clarity and accuracy of the scale can meet the specified requirements, but after printing, it is often necessary to Cured by heat.

With the advancement of science and technology, the application of laser marking has made up for the shortcomings of the above marking methods. It basically covers the application range of screen printing. It can not only carry out basic scale marking, but also mark the product date, Lot numbers and unique visual and tactile effects are marked as permanent and non-erasable. At present, glass marking is one of the most common glass processing processes.

However, in order to achieve high-quality marking on glassware, we need to face two problems: one is the brittleness of glass, and the other is the curved surface of glassware. Therefore, it is necessary to select the appropriate laser and marking parameters.

If an infrared nanosecond laser is selected, glassware is susceptible to heat during marking, which may cause cracks, thereby affecting the performance of the final product. Therefore, a UV laser with a cold working effect can be used for marking. RFH 355nm UV nanosecond solid-state laser, with excellent structure, stable and reliable performance, is very advantageous in laser marking applications. Its pulse width is less than 20ns, and with the high photon energy of ultraviolet light, marking is not heat treatment in essence, and this working method does not generate heat.

To achieve uniform marking on the glass surface, in addition to the scanning method, speed, scene range and other factors of the galvanometer, it is also affected by the focal depth of the focusing spot, and the beam quality, spot size, field lens, etc. will affect the focal depth. This 355nm ultraviolet nanosecond solid-state laser beam quality of RFH is high (M2<1.2), and it can easily obtain a finer spot diameter, which can reach micron level (about 20um), and high peak power. By adjusting to the appropriate marking parameters, The edge of the mark is delicate and smooth, and the precise minimum scale value can be obtained, and the scale can be firmly "branded" on the glassware.

In addition, in order to enhance the anti-counterfeiting function, laser marking can also be used to effectively assign codes on the utensils, and users can use the QR code to check the authenticity of the product, which can serve multiple purposes.
