After being discovered in the 20th century, laser has been widely used in many fields such as industry, military, medical communication, etc., with the characteristics of high energy, monochromaticity and directional emission.

At the same time, laser is also a double-edged sword. While intelligent creation promotes social progress, it will also cause certain harm to the human body if used improperly. The laser wavelength is 1060-1080nm, which belongs to invisible light and has greater harmfulness

When operating the laser equipment, you need to wear safety goggles, so when using the laser equipment, you must follow the correct operating requirements and do a good job of protection.

How to choose laser protective glasses

1. Laser characteristics

Reasonable selection according to the wavelength and power density of laser output

2. Optical density OD

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

3. Visible light transmittance VLT

VLT value is lower than 20%, and laser protective glasses need to be used well

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

5. Protective glasses must be able to protect the side from laser damage, and must not cause reflective laser damage to others

Safety signs during laser operation

Before using the laser, ensure that all electrical wiring connections are normal.

It is forbidden for untrained personnel to operate the laser equipment. Before switching on the AC main power supply, it is necessary to ensure that the main power supply is well connected to reduce the possibility of electric shock, prevent human injury caused by electric leakage due to damp environment, and use the laser equipment strictly in accordance with the operation sequence
