Crystal Engraving: Green Laser vs. Ultraviolet Laser
When comparing green laser engraving and ultraviolet (UV) laser engraving, you see clear differences in precision, speed, and material compatibility. The HeatSign HS-GL20P uses a 355 nm UV laser, which delivers finer detail and cleaner results than traditional 532 nm green lasers.
UV lasers have a smaller spot size and lower thermal impact, so they engrave crystal and glass without cracks or burns, producing smoother and more intricate 2D or 3D effects. In contrast, green lasers generate more heat, which can cause micro-fractures or uneven finishes on delicate materials.
