Introduction

Red and near-infrared laser sources are widely used across Australian medical, laboratory, and industrial settings, particularly in diode-based systems and therapeutic light applications. Although these wavelengths are often perceived as lower risk than higher-energy lasers, cumulative exposure and reflected beams can still exceed safe ocular limits. The LG-004 laser safety glasses are designed to deliver certified protection across a broad red and infrared spectrum while supporting compliance in regulated workplaces.

Wavelength Coverage for Red and Infrared Sources

The LG-004 provides continuous protection from 625 nm to 850 nm, addressing common exposure risks associated with red diode lasers, infrared LEDs, and photobiomodulation devices.

Key attenuation performance includes:

• OD 4+ across 625–850 nm

• OD 5+ at 633 nm

• OD 5+ from 190–400 nm, extending protection into the ultraviolet range

This coverage supports facilities operating mixed optical systems or ancillary UV-emitting equipment.

EN207 L-Ratings and Lens Markings Explained

The eyewear carries detailed EN207 resistance markings, confirming performance against various laser emission modes:

• 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 markings:

• 190–400 nm – OD 5+

• 180–315 nm – D LB7 + R LB3

• 315–395 nm – D LB5 + R LB6

These ratings verify resistance to continuous wave, pulsed, and diffuse reflection exposures within the specified ranges.

Fit, Coverage, and Usability

The LG-004 features a universal fit-over frame, allowing use over prescription eyewear without compromising stability. Adjustable arms and wraparound side shields enhance peripheral protection and improve wearer compliance during extended use.

With a 12% visible light transmission (VLT), the lens balances functional visibility with robust attenuation at critical wavelengths.

Compliance, Construction, and Included Accessories

Manufactured in the USA, the LG-004 is independently tested to AU/NZS 2211.1:2004, ANSI Z136, EN207/208, and CE standards. The lightweight yet durable frame is designed for frequent use in demanding environments.

Each pair includes a protective case, adjustable head strap, and cleaning cloth, and is supported by a 24-month warranty.

Conclusion

The LG-004 laser safety glasses offer dependable, certified protection for red and near-infrared laser applications commonly encountered in Australian professional settings. Their broad wavelength coverage, EN207 ratings, and practical fit-over design make them a reliable solution for maintaining eye safety and regulatory compliance.
