Certified Laser Safety Glasses

Features

Absorptive Dye Encased in Hardened Polycarbonate Lenses (Resistant to Breaking)*
Surface Scratches Do Not Reduce the Optical Density of the Lenses
Protection Lasts for a Minimum of 10 seconds at Maximum EN 207 Rated Exposure (See Specs Tutorial Tab)
Laser Glasses Available in Multiple Frame Styles
Certificates of Conformity Available for Compliance with:
- ANSI Z136.1 Standards for Safe Use of Lasers (Except LG16 Series)
- ANSI Z87.1-2003 Standards for Occupational and Educational Personal Eye and Face Protection Devices (Except LG16 Series)
- EN 207 Standards (Except LG14 Series, See Specs Tutorial Tab)
- EN 208 Laser Alignment Standards (LG13 and LG14 Series Only, See Specs Tutorial Tab)

These Laser Safety Glasses provide CE certified laser radiation protection. The lenses of all glasses except for the LG11 series are made from absorptive dye encapsulated in hardened polycarbonate, which provides superior resistance to breakage and prevents minor scratches from affecting laser protection. The LG11(A) Laser Safety glasses use a Schott glass substrate.*

The optical density (OD) and LB-Rating for specific wavelength ranges are indelibly printed on the lens or frame for permanent identification without blocking the field of view. For a complete list of optical densities and LB-Ratings, please click on the row corresponding to each item # in the selection guide to the right.

Thorlabs offers laser safety glasses in up to four different frame styles (see the Frame Styles tab for details). The universal style frame* can be worn over prescription glasses and features side and top shield protection from peripheral laser radiation. The comfort style frame features detachable inserts for prescription lenses (please consult your doctor to fit lenses for the inserts) and an extended nose piece that may be more comfortable for users who have a low nose bridge. The sport style frame is designed to wrap around the user’s face, providing full laser protection with a continuous field of view. These styles also include a slip-on neck strap. Finally, the modern goggle style comes with detachable inserts for prescription lenses and an adjustable strap, making it the most secure of the frame styles.

Each pair of laser safety glasses comes with a protective storage case and a cleaning cloth.

Care Instructions
When not being used, the laser safety glasses should be stored in their protective case and in an area where the temperature does not exceed 80 °F (26.6 °C). The laser safety glasses can be cleaned using a dilution of isopropyl alcohol (<10%) and wiped with a cotton swab. The cleaning cloth included with each pair of laser safety glasses can be used for removing dust from the surface of the lens. These lenses may also be cleaned with an ultrasonic cleaner or dish soap and water; the laser safety rating will not be affected by either cleaning procedure.

Picking the Appropriate Laser Safety Glasses
Since the correct choice of laser safety eyewear depends upon many local factors that cannot be evaluated remotely, including the beam path, laser parameters, and lab environment, Thorlabs cannot recommend specific eyewear for your application. We would recommend discussing your needs with your organization’s laser safety officer.

*Please note that LG11(A) Laser Glasses use a Schott glass substrate and may not fit over prescription glasses due to the different design. To ensure CE compliance, only the universal and comfort style goggles are offered with this substrate.
