Laser safety eyewear plays a vital role in ensuring safe working conditions when using red and infrared laser systems. The LG-004 safety glasses are designed to protect across a wide range of wavelengths from 625 nm to 850 nm, covering both visible red and near-infrared emissions.
Certified Standards
These glasses are fully certified to Australian and international laser safety standards, including AS/NZS IEC 60825, AS/NZS 1336, and EN207/208. Meeting these requirements ensures they provide appropriate optical density (OD) and resistance levels against defined laser wavelengths.
Protection Ranges
The optical densities (OD) marked on the eyewear indicate the level of attenuation provided:
-
625–850 nm → OD 4+
-
662–835 nm → OD 5+
-
633 nm → OD 5+
-
190–400 nm → OD 5+
This wide coverage means they can reduce exposure from both visible red diode and helium–neon lasers as well as near-infrared sources.
EN207/208 Ratings
The EN ratings printed on the glasses give further detail on their protective performance against direct and scattered laser exposure:
-
315–400 nm: LB6
-
625–830 nm DIR LB4, 830–850 DIR LB3
-
625–670 nm LB4, 800–830 nm LB4
-
670–800 nm LB5
These ratings provide confidence in the glasses’ suitability for both laboratory and industrial laser applications.
Common Laser Wavelengths Covered
The protection range includes many common red and near-infrared wavelengths, such as:
-
632.8 nm (He-Ne lasers)
-
635 nm, 650 nm, 660 nm, 670 nm (red diode lasers)
-
680–690 nm laser sources
-
785 nm, 808 nm, 810 nm, and 830 nm (infrared diode lasers)
This makes them suitable for diverse research, medical, and technical environments where multiple laser systems may be in use.
