Application
Direct Imaging
Ultra-Violet / Violet / Indigo
In the manufacturing of PCBs (printed circuit boards) and advanced semiconductor packages, our high-power lasers contribute to the maskless exposure of fine wiring patterns and solder resist. Unlike conventional photomask-based exposure, direct exposure enables high-precision and high-efficiency processing. As an essential technology for the miniaturization and advancement of electronic devices and semiconductors, it supports innovation.
Welding, Engraving, Marking
Blue / Indigo / Violet / Ultra-Violet
Blue lasers, with high energy density, are the ideal light source for welding, engraving, and marking. Our high-power and high-efficiency lasers contribute to the optimization of customers' manufacturing process and the improvement of quality.
3D printing
Ultra-Violet / Violet / Blue / Indigo
Our ultraviolet, violet, and blue lasers are ideal for additive manufacturing, commonly known as 3D printing, and are suitable for processing materials such as resin and metals (including copper and aluminum). The stable high-power laser light enables precise and high-quality forming.
Display
Violet / Blue
Our high-power and high-efficiency blue lasers enable bright laser displays. Compared to traditional lamp light sources, lasers have longer reliability, resulting in reduced maintenance costs.
Other Applications: Lighting, Biomedical, Sensing, Microscopy, Annealing, Agriculture
