A comprehensive resource for safe and responsible laser use
Kensington’s new $99 Ultimate Presenter with Virtual Pointer instead uses a software program to create an on-screen dot to highlight PowerPoint and similar computer presentations.
The company noted that “[b]right LED screens or safety regulations can pose limitations with traditional lasers.” A spokesperson said “The presenter overcomes the screen limitations and regulatory restrictions of traditional laser pointers….”
The screen limitations referred to are that bright screens can wash out a laser dot, especially a relatively dim dot such as the one from a Class 2 (<1mW) red pointer.

Kensington also continues to sell a line of presentation remotes that use red or green laser pointers.
From a September 26 2017 Kensington press release
In 11 percent of incidents, there was “physical aggression towards passengers or crew, or damage to the aircraft,” IATA reported.
IATA’s Director General stated “There is no easy answer to stem the rise in reported unruly behavior. We need a balanced solution in which all stakeholders can collaborate. The industry’s core principles can help to manage the small percentage of passengers who abuse alcohol. And it must be balanced with efforts by governments taking advantage of all their deterrence mechanisms….”
From a September 28 2016 press release from the International Air Transport Association. LaserPointerSafety.com is publishing this as an interesting comparison with the number of worldwide incidents of laser illuminations of aircraft, which are roughly on the same order of magnitude as that of air rage incidents.
From mid-July 2016 to late August 2016, more than 570 persons have gone to the main government hospital in Srinagar, Kashmir for treatment of eyes that have been damaged by “birdshot” (lead pellets) fired from shotguns into crowds by Indian security forces trying to break up protests and crowds.
An August 28 2016 New York Times article describes some of the lead pellet-caused eye injuries:
“The patients have mutilated retinas, severed optic nerves, irises seeping out like puddles of ink.”
“[A] patient’s eyelids have been stretched back with a metal clamp, so his eyeball bulges out of glistening pink tissue. The surgeon sits with his back very straight, cutting with tiny movements of his fingers. Every now and then, a thread of blood appears in the patient’s eye socket. The patient is 8 years old…. Slowly, as residents stood around him in hushed silence, the surgeon flattened out the boy’s retina, as thin and delicate as a lace doily, and used a laser to reattach it to the back of his eye.
“In most cases, it became clear, the pellets had burst into through the cornea and out through the retina, leaving little hope of fully restoring vision…. ‘Once it goes in the eye, it rotates like this, and destroys everything there inside,’ Dr. Qureshi said. ‘It’s physics. This is a high-velocity body. It releases a high amount of energy inside. The lens, the iris, the retina get matted up.’”
The author, Ellen Barry, notes that “….most countries do not use them on unarmed civilians, as the pellets spray widely and cannot be aimed…. This year, the use of pellets on Kashmiri protesters increased sharply, with the police firing more than 3,000 canisters, or upward of 1.2 million pellets, in the first 32 days of the protests, the Central Reserve Police Force has said.”
