The LG-338 laser safety glasses are designed to provide broad-spectrum protection across multiple commonly used medical and industrial laser wavelengths. These include Nd:YAG lasers operating at 1064 nm, Alexandrite lasers at 755 nm, and frequency-doubled green YAG lasers at 532 nm. The eyewear also covers extended near-infrared and visible regions, offering protection from 190 nm up to 1079 nm.

Optical Density and Coverage

The LG-338 lenses are marked with the following optical densities (OD), showing the level of laser attenuation at each wavelength band:

• 980–1064 nm: OD 7+

• 190–534 nm: OD 7+

• 750–760 nm: OD 7+

• 720–770 nm: OD 5+

• 770–850 nm: OD 4+

• 925–1070 nm: OD 6+

• 850–1079 nm: OD 5+

These optical densities indicate the lens’ ability to block laser radiation across overlapping spectral regions, particularly those used in Nd:YAG and Alexandrite systems.

L-Ratings and Certification

The L-ratings (EN 207/208) indicate the protection levels under specific laser exposure conditions:

• 400–534 nm IRM LB6

• 750–760 D LB5

• 750–760 IR LB7

• 980–1064 D LB5

• 980–1064 IR LB7

These values demonstrate compliance with European and international laser safety standards, confirming resistance to both continuous-wave and pulsed laser exposure within the specified wavelength ranges.

Standards and Compliance

The LG-338 model meets worldwide laser safety standards, including:

• FDA, AU/NZ IEC 60825.14:2014, EN 207/208, and CE Marking.
  Such compliance ensures suitability for medical, cosmetic, and industrial environments where certified eyewear is required.

Transmission and Visibility

With a visible light transmission (VLT) of 22 %, the LG-338 lenses maintain good visibility in clinical or laboratory settings while still providing high optical density against laser radiation.
