1: This glasses mainly protect the wavelengths of 180-540nm, 750-1100nm; Optical Density: 180-540nm, OD=6+; 750-760nm, OD=4+; 760-780nm, OD=5+；780-1100nm, OD=6+.
2: Optical density is a complex property of materials, which can slow down the propagation speed of light and produce a refraction effect;
3: Different lasers (and corresponding wavelengths) have different effects on the human eye; in general, the greater the optical density, the better the protection effect.
Why do you need laser safety glasses (must!)
1: Laser safety glasses, the purpose is to prevent laser exposure.
2: There are usually two types of lasers. Lasers between 400nm-780nm are visible light and visible light. Lasers above 780nm are infrared light and are usually invisible.
3: High-energy laser, the most common is optical 1064nm (optical fiber); 10600nm (carbon dioxide laser), invisible to the human eye. For example, if the light hits the human eye, the human eye does not respond at all, and it is not known to close the eye in time to prevent it. If the laser energy is slightly stronger at this time, it may cause blindness. (Phenomena: Unconscious and sudden blindness).
Summary: If you value your eyes, these glasses are a must-have for you.
1: When conducting high-energy laser experimental research, not only should protective glasses be worn, but there should be no reflective objects on the whole body. Like a watch.
2: Laser protective glasses are mainly used to prevent laser spots and stray light. Even with laser goggles on, people can’t look directly at the laser.
3: Please do not look directly at the laser, otherwise it will cause irreversible and permanent damage to the eyes.
