The LG-090Z laser safety glasses provide certified eye protection for wavelengths commonly used in surgical and medical laser systems, including Holmium, CO₂ and Thulium lasers. Their neutral lens tint and semi-frameless construction support accurate visibility and an unobstructed field of view, which is important during hands-on clinical procedures.
Optical Density and Wavelength Protection
The LG-090Z lenses provide attenuation levels suitable for medical environments where high-energy infrared laser exposure is present. The marked wavelength protection includes:
| Wavelength Range | Optical Density |
|---|---|
| 2100nm (Holmium) | OD 5+ |
| 10,600nm (CO₂) | OD 6+ |
| 1927nm & 1940nm (Thulium) | OD 4+ |
These protection levels target application areas such as soft-tissue ablation, lithotripsy and endoscopic surgical procedures.
CE and EN207/208 L-Ratings
The glasses provide documented L-ratings on the frame and lenses, confirming their tested resistance to direct beam exposure under defined pulse and continuous-wave conditions. Relevant ratings include:
| Wavelength Range | EN207/EN208 CE L-Rating |
|---|---|
| >1800–3000 nm | DI LB4 |
| 5200–11000 nm | DI LB4 |
| 790–<808 nm | DIRM LB3 |
| 808–840 nm | DIRM LB4 |
| 1400–1450 nm | DI LB1 |
| >1450–1650 nm | DI LB2 |
| 190–400 nm (UV) | OD 5+ protection |
These ratings are based on tolerance to energy levels under specific exposure conditions.
Lens Visibility
The LG-090Z features a 41% Visible Light Transmission (VLT) neutral filter, allowing a clearer color view of tissue, instruments and display monitors while still filtering targeted wavelengths. Higher VLT is beneficial in theatre and clinical settings where fine detail and color perception support decision-making.
Construction and Fit
The semi-frameless design increases the viewing area, and the universal fitover format accommodates both users with and without prescription glasses. Adjustable arms and a head strap assist in maintaining a secure position during procedural movement.
The frame includes:
-
Side shields for peripheral coverage
-
Flexible construction intended for routine clinical handling
-
Lightweight structure suitable for extended wear
Safety Standards
The LG-090Z is certified to meet the following requirements:
-
AU/NZS 2211.1:2004
-
ANSI Z136 (US)
-
EN207/208
These standards indicate compliance with labelling requirements, impact performance, and tested protection for specific medical wavelengths.
Accessories
