What types of laser engraved glasses are there?

The principle of laser engraving is to use the characteristics of the interaction between laser beam and material to perform cutting, punching, scribing, shadow engraving and other processing on materials.Laser engraving produces stunning precision but can harm your eyes and even cause permanent damage if you're not adequately protected. The right laser safety glasses will protect your eyes while you create beautiful products.  

Types of protective glasses for laser engraving: CO2, Fiber, and Blue

When working with lasers, the type of laser safety glasses you'll need depends on your specific laser system.

CO2 Laser Safety Glasses

CO2 lasers operate in the far-infrared region, usually around 10,600 nanometers (nm). They are commonly used in engraving, cutting, and welding. Safety glasses designed for CO2 lasers typically use materials like polycarbonate or special composite blends that effectively block or reduce infrared radiation. These glasses' OD is usually high to deal with the higher power levels that CO2 lasers.

Fiber Laser Safety Glasses

Fiber lasers usually operate at wavelengths around 1,064 nm but can range between 1,000 and 1,100 nm. These lasers are often employed in metal marking, engraving, and medical applications. The safety glasses for fiber lasers typically use glass lenses because they better protect against these specific wavelengths. Glass lenses also offer high OD levels and better visibility compared to polycarbonate lenses at these wavelengths.

Blue Laser Safety Glasses

Blue lasers usually operate at wavelengths around 450 nm . These lasers are often employed in metal marking and engraving. Safety glasses designed for blue lasers usually use materials such as polycarbonate or special composite materials, which can effectively block or reduce blue laser radiation. These glasses usually have lower OD and better visibility.
