ExtremeUV Index

In other words, if a protection goggle has an O.D. (Optical Density) equal to 3, this means that only 1 photon of light out of 1,000 (10³) will be pass thru the protection goggle, if it has an O.D. equal to 7, this means that only 1 photon of light out of 10.000.000 will be pass thru the protection goggle. This means the light passing thru will be 1000 or 10.000.000 times less for the frequency indicated.

Visibility Light Transmission (VLT) – Color and visibility of specific color ranges often are significantly affected by laser glasses and goggles. Think about sunglasses - when wearing sunglasses to block the sun, (often less expensive) sunglasses do an effective job of blocking the sun. However, everything is much more difficult to see because not a lot of light generally is coming through. Other times with (typically more expensive) sunglasses, the sun is blocked and everything else looks very similar to how it would without the glasses.  We have selected the lenses with the highest VLT % with the highest protection possible for your Eyes and giving the nicest and clearest view of the objects.

This class 4 covers most powerful and dangerous lasers. Class 4 lasers can cause permanent eye injury through either direct exposure or reflected light. They can also burn the skin and cause fires. ALL lasers used in welding industry, surface cleaning industry and metal cutting industry are Class 4.

ExtremeUV wavelength

The key difference between optical density and absorbance is that the optical density measurement takes both, the absorption and scattering of light, into consideration whereas absorbance measurement takes only the absorption of light into consideration.  Optical density (OD) is the degree to which a refractive medium retards transmitted rays of light while absorbance is a measure of the capacity of a substance to absorb light of a specified wavelength.

When deciding which kind of lenses to purchase, a good place to start is with the visible light transmission (VLT). The higher the VLT percentage is, the lighter the lens tint will be. Higher VLT percentage lenses will allow for more light to travel through the lens that will then hit the eye. Alternatively, lenses with a lower VLT percentage will have a darker tint and will block more light from coming through to the eye.

Lasers used for laser welding applications radiate in the infrared spectra, which are not visible to the humaneye.  The intensive fiber laser light radiate in the visible spectrum but invisible for humans, is especially dangerous to the eye. Fibre laser radiation penetrate through to the retina which can be destroyed irrevocably by relatively little radiation. Misdirected laser radiation can come directly from the laser and threaten the eyes as a result of a faulty parameter setting, an opened cover, a displaced mirror etc. Other hazards include skin burn or inflammation from combustible materials as a result of misdirected laserradiation. The greatest hazard, however, usually stems from reflected laser radiation: the major share of the laser radiation is reflected by coldmaterial first. To this we can add reflections of work piece edges, as a result of turbulence in the weld pool etc.  Misdirected radiation and reflections must be blocked off. That is why the law stipulates that the laser beam and the work zone must be in an enclosure. Beyond that, all those present, and the machine operators in particular, should wear protective goggles that are appropriate for the laser radiation being used.  Fbre laser radiation are very dangerous to the eye and require special protective measures andapproved safety goggles.
