The news that a small laser pen hurts the child's eyes has occurred. For optoelectronics in the laser industry, laser safety is closely related to the company and the individual, and it cannot be ignored.
Laser safety incidents can result in personal injury, damage to the laser, and damage to equipment and equipment in the facility. From the perspective of artifacts, systems, and people, we must pay attention to laser safety.
The first step is to understand the laser safety level and logo
The laser safety level classification refers to the damage mechanism of the laser system to human tissues and the defined index of the degree of damage caused. For laser products that cause Shanghai to be human, a warning label with the wording of the laser hazard class should be attached.
The International Electrotechnical Commission standard (IEC 60825-1) classifies laser products into the following seven grades based on the wavelength of the laser product and the maximum output laser power: 1, 1M, 2, 2M, 3R, 3B, 4. The 1M and 2M grades represent the same level of safety as the 1st and 2nd grades. However, when using optical equipment such as telescopes, the degree of damage may be amplified to exceed the damage of Levels 1 and 2. Level 3 is also divided into two sub-levels, 3R and 3B.
In addition, we must pay attention to the complexity of laser equipment systems and the damage that can occur during laser processing. On the one hand, the typical non-beam hazard in laser production systems is manifested in mechanical hazards, electrical hazards, functional safety, heat. Hazard, vibration, noise; on the other hand, other toxic substances and secondary radiation hazards generated during laser processing.
The second step, pick up your protective gear
Laser safety glasses
In the face of laser damage, start with safety glasses. When selecting goggles, carefully consider the operating parameters, MPE values and working wavelengths, and select the appropriate goggles.
By the way, we supply laser safety glasses with good quality and very competitive price.
