The lasers, marketed as tools to point out stars at night, are much more powerful than laser pointers used by lecturers.They can be seen up to 25,000 feet away and are used by bird watchers, astronomers and lecturers to point out faraway objects.In 2009, a Southern California man was sentenced to 2 1/2 years in a federal prison after he became the first person in the nation convicted at trial of interfering with pilots by aiming lasers at their planes. He had aimed a hand-held Powerful Laser Pointer at two Boeing jets as they were landing in May 2008.In 2005, a New Jersey man was arrested and charged under the Patriot Act for aiming a green laser at a small jet flying over his home near Teterboro Airport a year earlier. The man, who was eventually sentenced to probation, said he had been using the device to point at the stars from his backyard.the laser pointers responsible for these incidents are cheap, readily available and, to date, legal for purchase. Although marketed as tools for use as pointers for presentations or for highlighting astronomical objects in the night sky, a combination of accidental misuse and malicious abuse has turned this technology into a potentially dangerous weapon. Legislation is being considered and implemented but is unlikely to eliminate the availability of these devices, especially from online sources. Due to its strong straight light, laser pens (pointers) are widely used in teaching, astronomy etc. Just push the button, then you will see striking light shoot. It is alright to point at any targets such as photos, Laser Pointer , monitor etc. It may be the proferred choic for astronomy fans, laser fans.We live across the street from a neighbor who has her laser lights on 24 hrs/7days a week. She shines her laser lights in other neighbors faces, heads, at children, family pets, windows of houses, plants and trees (which are singed from being over exposed/burned by laser lights), aircraft, on our parked vehicles, & vehicles driving down the street. When I have been in the front yard my eyes and face start burning from the lasering. The police have been called several times, but state that they cannot do anything.

Authentic aluminum alloy ensures the durability of this 2000mW High Power Attacked Head 1000mW Laser pointers Suit. This professional laser pointer is easy to operate. What's more, fine craftsmanship makes it smooth to hold. Just gently press the switch button; you will notice a beam of strong blue light sending out from the laser pen. With such a portable tool, you can point at any target as far as 5000 meters. It is suitable for many industries, such as tourism, wild exploration, mine stope etc. Additionally, there is two 1200mA batteries, a box and a charger included, which enables the laser pen reusable and convenient to carry. Above all, designed with attacked head, it can well protect you as well. It is really a bargain. How can you refuse such an economical product?As if airplane pilots didn’t already have enough to worry about, they’re now facing record levels of attacks from laser pointers while landing their planes.The FBI’s terrorism unit is investigating two incidents last week at New York City’s LaGuardia airport in which airplane pilots were temporarily blinded by green lights shone from several miles away. They are thought to have come from small, handheld laser pointers, such as the battery-powered ones often used in classrooms. laser pen 1000mw Green lights that hit at a particular angle can illuminate the whole cockpit with a bright green or red light, and blind the pilots as they’re trying to land.

Under certain conditions, laser light or other bright lights (spotlights, searchlights) directed at aircraft can be a hazard. The most likely scenario is when a bright visible strong laser pointer light causes distraction or temporary flash blindness to a pilot, during a critical phase of flight such as landing or takeoff. It is far less likely, though still possible, that a visible or invisible beam could cause permanent harm to a pilot's eyes. Although Laser Pointer Green weapons are under development by the military, these are so specialized, expensive and controlled that it is improbable for non-military lasers to cause structural damage to an aircraft.Aviation hazards from bright light can be minimized or eliminated in two primary ways. First, users on the ground can exercise caution, to prevent or minimize any laser or other bright light being directed in airspace and especially towards aircraft. Second, pilots should have awareness of laser/aviation hazards and knowledge of basic recovery procedures in case of laser or bright light exposure.Pointing a laser at an aircraft can be hazardous to pilots[1] and has resulted in arrests, trials and jail sentences. It also results in calls to license or ban laser pointers. Some jurisdictions such as New South Wales have restricted laser pointers as a result of multiple incidents.Available protective eyewear blocks laser pointers but can compromise visibility in general, sacrificing the ability to distinguish critical lights and displays. However, new advances in thin-film coatings on glass and plastic optics allow for solutions that selectively reflect light from one or more laser pointers while providing high transmission and good color discrimination to the wearers.

These effects suffered by flight crew vary with the distance of the attacker and divergence of the laser used in the attack. Typical laser pointers have a divergence of 1mrad, resulting in potential eye hazard at approximately 20m, temporary flash-blindness to 80m, glare up to 400m and distraction at distances up to 3km. It is evident the dominant threat comes from the potential hazards associated with a flight crew’s inability to Attacking Laser Pointers pilot an aircraft because of disorientation, disruption or distraction.And it is not just pilots but also police officers, train drivers and other professional groups who are repeatedly under threat from green laser pointers . The dangers of these attacks are severe and range from permanent eye injury to serious accidents. Today, the choices exist for potential victims of these attacks to adopt appropriate eyewear choices for their environments to maintain their personal safety and that of the people in their care.
