After being discovered in the 20th century, laser has been widely used in many fields such as industry, military, communication and medical treatment, making important contributions to the development of human society, thanks to its characteristics of high energy, monochromaticity and directional emission. However, laser is also a double-edged sword, which can intelligently create everything and promote social progress; If it is used improperly, it will also cause some harm to human body.

The laser wavelength is 1060-1080nm, which is invisible and more harmful.

Therefore, in the process of using the optical equipment, we must follow the correct operation requirements and do a good job of self-protection. Safety glasses must be worn when operating laser equipment.

Guidance on the selection of laser protective glasses

1. Laser characteristics:

Reasonable selection shall be made according to the output wavelength and power density of the laser.

2. Optical Density (OD):

The higher the OD value, the stronger the protective ability of the laser protective glasses.

3. Visible Light Transmission (VLT):

The VLT value is less than 20%, and the laser protective glasses should be used in a good lighting environment.

4. Lens material is non-toxic, odorless and non irritating.

5. The protective glasses shall be able to protect the side from laser damage and shall not cause reflective laser damage to others.

The laser processing laser belongs to Class IV laser, and the laser beam will cause irreversible harm to the human body, burn the skin and damage the eyes. You should protect your eyes at all times. Never point your eyes directly at the laser output port to avoid injury. Do not use reflective materials to shield the laser beam, so as to avoid injury to others after the laser beam is reflected. Do not let the emission beam reach the eye at any time. In addition, the laser beam may ignite or detonate flammable and explosive substances, so special care should be taken when processing such substances.

Safety signs during laser operation

Before using the laser, make sure that all the electrical connections are normal. Ourui laser is selected for the Wanwa laser cutting machine. The colleague who prevents the laser from leaking shall ensure the safety of electricity use.

It is forbidden for untrained personnel to use the laser equipment. Before switching on the AC main power supply, ensure that the main power supply is connected to a good ground to reduce the possibility of electric shock, prevent personal injury caused by electric leakage due to humid environment, and use the laser equipment in strict accordance with the operating sequence.
