How to classify the laser safety level
Oct 16, 2019
As laser technology enters our production and life more and more widely, the safety of laser products is getting more and more attention, because some laser products can be used safely, and some can cause damage to our skin and eyes. Laser products such as laser cutting machines, laser welding machines, laser marking machines, etc., if used improperly, can even cause fire, electric shock, burns, and cause serious damage to the human body. So how do we know if a laser product can be used safely?
Overview of laser safety levels:
In order to facilitate the clear identification of the hazard level of the laser, we can classify the degree of damage that the human body can cause by laser. Understanding the hazard level of lasers is very necessary for ordinary consumers and professional operators. By correctly understanding the level of lasers and understanding the degree of hazard and precautions that can be represented, many laser injury accidents can be avoided.
| Class 1 | No harm |
| Class 1M | There is no danger in normal use, but the use of optical equipment such as magnifiers and telescopes increases the risk. |
| Class 2 | Safe to use, but the eyes can't look directly at the laser beam. |
| Class 2M | Safe to use, but using optical equipment such as magnifiers and telescopes increases the risk. |
| Class 3R | If it is discharged directly or through the optics to the beam, it may cause damage to the human eye. |
| Class 3B | Direct or transient exposure to the laser beam will cause damage to the eyes or skin. |
| Class 4 | Not only direct or transient exposure to the laser beam can damage the eyes and skin, but also the stray light from the laser beam, which can also damage the eyes and skin, as well as potential fire hazards. |
JRT's laser range sensor uses a second-class safety laser that can be used safely, so you can buy it with confidence.
