CO₂ lasers operate at 10.6 microns (10,600 nm) and can cause serious eye injury due to their high-energy infrared output. The LG-009 OD 7+ CO₂ Laser Safety Glasses are designed to meet the protective requirements for this wavelength and provide verified attenuation consistent with international laser safety guidelines.
Optical Density Requirements for CO₂ Lasers
OD 7+ eyewear provides a reduction factor of ten million at 10,600 nm.
Compared with lower OD levels:
-
OD 5+ = 100× less protection
-
OD 6+ = 10× less protection
This makes OD 7+ the appropriate rating for many medical, scientific, and fabrication environments using CO₂ systems.
Visible Light Transmission
Despite offering high protection in the infrared and ultraviolet bands, the lenses maintain a visible light transmission of 93%, supporting clear visibility of the workspace. This is particularly important in precision applications or procedures requiring continuous visual monitoring.
Frame and Fit Features
The frame is designed for universal compatibility and can be worn with or without prescription glasses. Adjustable arms allow the glasses to fit a wide range of head sizes, and the large lens design supports an open field of view. Each pair includes a head strap, lens cloth and protective case.
Safety Standards and Testing
The LG-009 glasses meet the requirements of:
-
AS/NZS 1337.5
-
AS/NZS ISO 19818.1:2023
-
AS/NZS IEC 60825.14:2014
-
AS/NZS 1336:2014
-
FDA (USA)
-
CE / EN207 & EN208
The CE-EN207 L-ratings outline the tested exposure resistance:
-
190–315 nm: D LB7 + IR LB4
-
315–398 nm: DIRM LB5
-
9000–11000 nm: DI LB3
Wavelength Coverage
The glasses provide OD 7+ protection across three key wavelength bands:
-
10,600 nm (primary CO₂ wavelength)
-
9000–11,000 nm infrared region
-
190–398 nm ultraviolet region
This allows the eyewear to support both CO₂ laser use and environments where UV sources are also active.
