Infrared laser systems such as Holmium (2100 nm), Thulium (1927–1940 nm), and CO₂ (10 600 nm) are widely used in urological, dermatological, and ENT surgery. These wavelengths are absorbed strongly by water in biological tissue, enabling precise ablation with minimal collateral damage—but they also pose a significant risk to unprotected eyes.
The LG-090 laser safety glasses are engineered to provide high-level attenuation across this infrared range.
-
OD 5+ at 2100 nm – Holmium protection
-
OD 4+ at 1927–1940 nm – Thulium protection
-
OD 6+ at 10 600 nm – CO₂ protection
This coverage makes the LG-090 suitable for a broad spectrum of surgical and laser therapy systems.
Optical and Physical Characteristics
The LG-090 utilises precision-formulated infrared-absorbing polymers tested to EN207/208 and ANSI Z136 standards. The EN207 L-ratings (DI LB4 to DIRM LB4) confirm resistance to both direct and reflected laser exposure.
With a 41 % VLT neutral filter, these glasses maintain clear visibility of patient and instrument fields under operating lights—an essential factor in maintaining precision during procedures.
Design and Ergonomics
The universal fit-over frame accommodates prescription glasses and includes side shields for peripheral protection. Lightweight construction reduces operator fatigue during long surgical sessions, while adjustable arms ensure a secure fit across multiple users in clinical settings.
Certifications and Reliability
Manufactured in the USA and compliant with Australian, US, and European laser safety standards, the LG-090 delivers internationally recognised reliability. The inclusion of a protective case, adjustable head strap, and lens cloth, along with a 24-month warranty, supports long-term professional use.
