Laser Cutting Operators: A Guide to Fiber Laser Safety Glasses

Fiber laser safety glasses (laser goggles, laser protection glasses, laser protective eyewear) can prevent or reduce laser damage to the human eye.

Laser safety goggles This is an efficient tool for eye protection, suitable for personnel who often work in laser scenes. Laser safe goggles can fully protect lasers and strong light in specific bands. Suitable for a variety of laser equipment. Visible light transmittance reaches more than 70% and optical density is above 5.0.

Laser safe goggles type:

Absorption type and reflective type, the former is used the most.

Goggles are a kind of glasses that play a special role. Different occasions require different glasses. Such as surgical glasses for hospitals, welding glasses for welding, safety glasses for laser engraving, safety glasses for laser cutting, etc.

Which laser type requires laser safety eyewear?

The bands are 355nm, 532nm, etc.

For laser types, safety glasses for laser are required for lasers in the 355nm, 532nm, 808nm, 1030nm, 1064nm and 10600nm bands.

Anti laser glasses are a special type of glasses that filter laser radiation and can absorb or reflect laser radiation of specific wavelengths, thereby protecting the eyes from laser damage.

Laser safety eyewear, also known as labor protection glasses, safety glasses and protective masks

Its main function is to protect the eyes and face from electromagnetic wave radiation such as ultraviolet, infrared and microwave, as well as damage from dust, smoke, metal and gravel debris, and chemical.

Types of fiber laser safety glasses

Protective glasses against solid debris

Used to prevent mechanical damage to the eyes from metal or gravel debris. Eyeglass lenses and frames should be sturdy in construction and resistant to impact. There should be a shield around the frame and ventilation holes in it. Protective lenses can be made of tempered glass, glue-bonded glass or copper wire mesh protective lenses.

Protective glasses against chemical

Protects against chemical damage to eyes from irritating or corrosive Ordinary flat lenses can be used, and the frames should be covered to prevent Usually used in laboratories, hospitals and other places, general medical glasses can be used universally.

Protective glasses against radiation

Protect your eyes from harmful effects of excessive ultraviolet rays and other radiation. The lenses are made of special glass that can reflect or absorb radiation, but can transmit a certain amount of visible light.
The lenses are coated with bright chromium, nickel, mercury or silver metal films that can reflect radiation;

Laser shield glasses are suitable for people

Laser cutting machine operators, computer operators, drivers, gas welders, electric welders, high temperature furnace operators, medical or industrial personnel when operating X-ray fluoroscopy;
Suitable for the protection of ultraviolet laser, excimer laser, neodymium glass laser, semiconductor laser, CO laser, neodymium-doped garnet laser, ruby laser, CO2 laser, gallium arsenide laser and other lasers.

Which brand of safety glasses laser is better?

NoIR Laser Company is an American manufacturer specializing in laser protective glasses (L.L.C. for short). NoIR’s leading craftsmanship and advanced laser protection technology brought about by more than 20 years of development can provide customers with a series of high-safety laser protective glasses, and its customers are all over the world.

NOIR laser protective glasses have extremely high cost performance, good protective performance, many standard models, high quality and durable lenses, and have passed relevant safety certifications. Its commonly used models include FG1, DBY, DBD, ARG, EC2, KTI, YG2, YG3, YLW, etc. It has also launched various new laser protective glasses such as YG4, YG5, RT1, RT2, RB1, HOY, IRD4, AG8, GRA and so on.

The protection level of NOIR laser protective glasses can reach OD7+ for all laser bands. There are also a variety of combinations of protection for different bands, and they comply with various relevant safety certification standards (CE certification, EN207 certification, etc.).

How to choose fiber laser safety glasses

Laser parameters:

Output wavelength, pulse width, power density.

Optical density

The greater the Optical Density (OD) value, the stronger the protective ability of laser protective glasses.

L grade

The higher the L level, the stronger the laser protection capability.

Visible light transmittance

The higher the visible light transmittance, there is not much impact on vision when wearing glasses or not wearing them. However, the transmittance of some laser protective glasses will be less than 20%. At this time, it will basically become unclear, and you need to consider adding auxiliary lighting.
