Red and near-infrared laser systems are commonly used throughout U.S. medical, research, and industrial facilities, particularly in diode-based technologies and therapeutic light applications. While often operating at moderate power levels, these wavelengths can still present serious retinal and thermal hazards. The LG-004 laser safety glasses are engineered to provide verified broadband attenuation and meet the requirements of ANSI-based laser safety programs.

Spectral Protection Range and Optical Density

The LG-004 delivers continuous attenuation from 625 nm to 850 nm, covering a wide range of red and infrared laser and LED sources.

Performance highlights include:

• OD 4+ from 625–850 nm

• OD 5+ at 633 nm

• OD 5+ UV protection from 190–400 nm, supporting environments with ancillary ultraviolet exposure

This makes the eyewear suitable for multi-technology laser workplaces.

EN207 Resistance Ratings and Exposure Modes

The lenses are marked in accordance with EN207 requirements, confirming resistance across multiple laser emission conditions:

• 625–670 + >800–830 nm – I LB4

• 625–830 nm – DR LB4

• 670–800 nm – I LB5

• 830–850 nm – DIR LB3

• 850–860 nm – DIR LB2

Ultraviolet resistance markings:

• 180–315 nm – D LB7 + R LB3

• 315–395 nm – D LB5 + R LB6

These markings validate performance beyond basic optical density ratings.

Visibility, Fit, and Peripheral Protection

The LG-004 offers a 12% VLT, allowing controlled visibility while maintaining effective laser attenuation. The wraparound frame design improves side coverage, reducing exposure from scattered or reflected beams.

A universal fit-over construction accommodates prescription eyewear, while adjustable temples enhance comfort and stability during prolonged wear.

Standards Compliance and Product Support

The LG-004 is manufactured in the USA and certified to ANSI Z136, EN207/208, CE, and AS/NZS 2211.1:2004 standards, supporting use in regulated U.S. laser environments.

Supplied accessories include a protective storage case, adjustable head strap, and lens cleaning cloth. The product is backed by a 24-month warranty.

The LG-004 laser safety glasses provide certified, broadband protection for red and near-infrared laser applications while supporting visibility, comfort, and compliance. Their extended wavelength coverage and verified EN207 markings make them a dependable choice for U.S. professionals managing laser-related eye hazards.
