Multi Wavelength Laser Safety Glasses

Laser safety glasses serve a multitude of purposes.

Laser Safety Glasses for Multi Wavelengths

Multi Wavelength Laser Safety GlassesThey can be used to guard against strikes from laser pointers. They provide protection for medical personnel and technicians who practice laser surgery and use diagnostic tools that involve lasers. They protect the eyes of dentists and dental hygienists, who increasingly count lasers as dental implements. They’re used by line workers and machinists, army and navy personnel, scientists and engineers.

Have you ever wondered how they work? One might assume that any laser safety eyewear is simply reduced to a tint that’s dark enough to block laser light, as welding glasses block the arc of a welding unit. But a quick glance at any pair of laser safety eyeglasses will prove that’s not the case…they’re not darker, just designed in different colors. Why?

Well, lasers work on light wavelengths, and colors do the same thing. Different lasers produce beams of varying strength on different wavelengths, and these wavelengths correspond to a certain color. Filter out that color and you also filter out the harmful, retina-damaging rays of the laser. Laser safety glasses attenuate or block the appropriate wavelength range and optical density of a given laser.

By absorbing relevant laser wavelengths (be they from red, blue, or green lasers) without blocking all light in the visible spectrum, laser safety glasses allow wearers to maintain adequate vision around lasers. They can see lighted instruments, technical readouts, cockpit displays, and more, while still enjoying eye protection from a direct or a scattered laser strike.

The ability of a lens to block a particular color and wavelength of laser is determined by Visible Light Transmittance, or VLT, a measurement of how much light penetrates the lens. The laser safety glasses at Phillips Safety are categorized by this classification. Here’s how they break down along the Visible Light Transmittance spectrum:

LS-PSPG Lens

  • 46.9% VLT
  • Protects from green beam reduction (most common source)

LS-PSPBG Lens

  • 43.0% VLT
  • Protects from both green and blue reduction

LS-PSPBGR Lens

  • 46.9% VLT
  • Protects from blue, green, and red beam reduction

Shop Laser Safety GlassesThese lenses can be ordered in several different frame styles, including fit-overs, wrap-arounds, and aviators, and in various frame colors. If you risk exposure to lasers, it’s important to determine which wavelength is present in those lasers…and arm yourself with a pair of laser safety glasses that are capable of diffusing all the wavelengths you’ll encounter.
