A blue light laser typically refers to a semiconductor laser. Its wavelength is approximately 450 nanometers. In the world of laser engraving, this blue light engraving machine acts like a "picky eater." It shows strong enthusiasm for some materials. Conversely, it completely ignores others. This "enthusiasm" depends entirely on the...
Laser Smoke An Overlooked Respiratory Health Risk
When operating laser cutting or marking machines, most people focus on the bright light. However, as the laser beam cuts materials, pungent laser fumes rise. As an expert, I must frankly state: the laser plume generated by laser processing often presents dangers as serious as direct beam exposure. I. Nanoparticles:...
CO2 Laser Tube High-Voltage Risks Grounding, Insulation, and Leakage Checks for Enhanced Laser Safety
Many novice users believe simply avoiding direct contact with live terminals ensures safety. However, high-voltage physics reveals electricity's "creeping" and "jumping" characteristics. Inadequate protection means current can silently reach you. It travels through humid air or metal casings, creating significant hazards. This underscores the critical need for robust laser safety...
