"The potential for injury increases as you increase the power output of the product," adds Boyd. "Certainly the potential for distraction or flash blindness or startling increases as well when you're talking about an overpowered laser for sale.
Flash blindness is a temporary loss of vision that occurs when the eye is suddenly exposed to intense light--even from an unintentional sweep of 5 in 1 Laser Pointer light across a person's eyes. The effect can last from several seconds to several minutes. Recent reports of flash blindness in pilots from laser lights beamed at aircraft have further heightened the agency's concerns.The FDA is working to identify manufacturers of overpowered green laser pointers and other illegal laser products and will take action to prevent these unsafe products from being sold in the United States.
It may sound like the stuff of urban legends, but it's true: The same 50mw Green Laser you've used in business presentations or to entertain your cat for hours on end could actually take down a plane. How can this be?According to the U.S. Federal Bureau of Investigation, the beam of light from a handheld laser pointer aimed at an aircraft from the ground can travel more than a mile [source: FBI]. Pilots who have experienced laser attacks from the cockpit compare the experience to having a camera flash go off in a pitch black car at night
These High Powered Laser Pointer produce an intense green beam that is highly visible under most conditions. In darkness and even low-light, the entire beam can be visible as it cuts through the air, making it an excellent long-range pointing device (as an astronomical aid to point out stars and planets, for example). Intensity is about 35 times brighter than a red 670 nm basic laser pen (or 10 times greater than red at 635nm; see our Spectral Scan for the eye's sensitivity to different wavelengths). Visible effects are greatly enhanced over water, in the fog, rain or snow and humidty, and at night. If one was to look from a distance in the direction of the laser, it would appear as the brightest source of light on the horizon for many miles.
This rare laser pointer produces a unique, novel, and amazing yellow beam. It is one of the first yellow laser pointers in the world. Visible effects are greatly enhanced over water, in the fog, rain or snow. When one looks in the direction of the laser, it will appear as the brightest source of light on the horizon from a distance of many miles. The yellow laser can be used for pointing, fluorescence exciting, Raman spectrum, biomedicine, laser light shows, etc. These are Class 3A ready to use devices. A simple collimator can be made (not included, see COLMIN1K below) that can extend the range up to x7!
We have a variety of green laser pointers available: there is a standard laser pointer; another with a focusing lens for adjusting the size of the dot; one is chrome plated for an elegant, 'executive' look; there is a laser with a 'switch' button that keeps it running until turned off; and a laser with multiple lenses that create different special-effects patterns.
