355nm UV laser
Uv laser has three distinct advantages in micromachining applications:
●The short wavelength can be used to process very small parts. The beam diffraction effect is a main reason to limit the minimum size of parts.
●Photons with high energy can directly destroy the chemical bonds of the molecules inside the material. This process is called "cold" processing process. Compared with visible laser and infrared laser, the heat affected zone is almost negligible.
●in nature most of the materials can absorb ultraviolet light, its characteristics make UV laser can process a lot of visible laser and infrared laser processing materials.
●Repeat rate adjustable
● External controllable
●Easy use & maintenance free
●Longlife operation
●High efficiency
●High reliability
