When selecting laser protective eyewear it is important to make sure that they have the correct markings on the glasses. Either on the frame or on the lenses themselves. To comply with US, European and International laser safety standards wavelengths and optical densities, L ratings and VLT is required to be marked on the glasses.

If you would like help selecting the most appropriate laser protective goggles for your requirements feel free to contact us at info@dioptika.com and one of our laser safety experts will be happy to help.

An example of the wavelength & optical densities are shown below.

1064nm - OD 7+

950-1070nm - OD 7+

1080-1090nm - OD 5+

840-950nm - OD 5+

808-840nm - OD 4+

190-400nm - OD 5+

Visible Light Transmission - 59%

L-Ratings are written as:

808-840 DIRM LB4
>840-950 + >1070-1090 DIRM LB5
>950-1070 D L6 + IRM LB7
