Laser pointers are hand-held devices available in different colours and emitting a low-power laser light typically in the visible range. They find applications where we need to highlight or pinpoint a particular thing like in Laser shows, concerts, educational and business presentations, etc. Laser pointers also make a potent signalling tool, even in daylight. Accurately aligned laser pointers are used as laser gunsights to aim a firearm as well as in optical alignment applications. Different wavelengths of red, orange, green, violet, blue and infrared too can be used as per application needs.
We have LCD TVs used as monitors connected to a computer in our conference room. Anyone have knowledge or suggestions for pointers for people to use while presenting material?
We"ve tried red laser pointers and they do not work because it reflects off the tv screen. I"ve heard green lasers work better, but can"t find anything that proves it would work.
This document interprets FDA regulatory requirements as they apply to laser pointers, explains the power limits for these products, and the applicable requirements for information for safe use and for promotional materials. The document also discusses inappropriate use of high-powered, battery-operated, portable lasers.
Lasers are generally classified according to the hazard posed by the amount and type of light they emit. Hazard classes range from Class I to IV with Class I lasers being non-hazardous and Class IV lasers being the most hazardous.Class I products include laser printers and CD players where the laser radiation is usually contained within the product. Products exceeding Class I permit access to some amount of laser radiation.
Laser pointers are hand-held lasers that are promoted for pointing out objects or locations. Such laser products can meet one of two definitions for laser products. The first is for “surveying, leveling, and alignment laser products” as defined by Title 21 of the Code of Federal Regulations (CFR) Section 1040.10(b)(39):
“Surveying, leveling, or alignment laser product means a laser product manufactured, designed, intended or promoted for one or more of the following uses:
Hand-held lasers promoted for entertainment purposes or amusement also meet the second definition, that of “demonstration laser products” as defined by 21 CFR 1040.10(b)(13):
“Demonstration laser product means a laser product manufactured, designed, intended, or promoted for purposes of demonstration, entertainment, advertising display, or artistic composition.”
21 CFR 1040.11(b) and 1040.11(c), limit surveying, leveling, and alignment, and demonstration laser products to Class IIIa. This means that pointers are limited to 5 milliwatts output power in the visible wavelength range from 400 to 710 nanometers. There are also limits for any invisible wavelengths and for short pulses. Pointers may not exceed the accessible emission limits of CDRH Class IIIa or IEC1 Class 3R.
Class IIIa or IEC Class 3R lasers can be dangerous. Class IIIa lasers can cause temporary visual effects such as flash blinding, which could distract or startle the person exposed. The risk of injury is very small when Class IIIa pointers are used responsibly because natural body motion of a person holding the pointer or motion of a person who might be exposed makes it difficult to expose the eyes for a long period of time. People also have a natural aversion to bright lights and are likely to close their eyes and turn their heads if exposed.
Lasers that emit between 5mW and 500mW output power are in Class IIIb or IEC Class 3B. Class IIIb lasers cannot legally be promoted as laser pointers or demonstration laser products. Product labels and user instructions must describe the hazard classification of the product and its output characteristics.
With any laser product, the potential for injury depends both on the product itself and how the product is used. Higher powered Class IIIb or IEC Class 3B lasers are dangerous and can cause either temporary visual effects or an eye injury.
Class IIIb hand-held lasers are too dangerous for use as pointers or amusement articles. Furthermore, promotion of Class IIIb or IEC Class 3B products for pointing or amusement violates FDA requirements and United States law. Manufacturers of such products may be required to repair, replace, or refund the purchase price of violative products distributed in the U.S. These products are also subject to detention and seizure by the U.S. Customs and Border Protection when imported.
Irresponsible use of more powerful laser pointers poses a significant risk of injury to the people exposed. Persons who misuse or irresponsibly use lasers are open to personal liability and prosecution.
Yes. Several states have registration requirements and annual registration fees for operators of Class IIIb lasers. Check with the Department of Health in your state for additional information.
The American National Standards Institute (ANSI) publishes standards for the Safe Use of Lasers2:Z136.1 American National Standard for the Safe Use of Lasers: 2000
The ANSI standards contain procedures for avoiding exposure to laser light, designation of a Laser Safety Officer, training of operators, and the posting of warning signs in laser operating areas for Class IIIb lasers. People who operate Class IIIb lasers should be familiar with these standards to ensure the laser is used safely. In cases where a laser pointer is misused and results in an injury or alleged injury, authorities may refer to these standards as criteria for appropriate use and safety precautions.
Yes, battery-operated, portable laser systems can be sold in the U.S., providing that they fully comply with the standard, are certified and reported, and are not Class IIIb lasers sold or promoted for pointing or amusement purposes.
People who operate Class IIIb portable laser systems should be familiar with the above ANSI standards for safe use of lasers. This ANSI series of standards includes specific information for the safe use of such laser products in their applications of use.
High-powered hand-held lasers are a significant hazard to law-enforcement in crowd control and riot situations, inducing flash blindness and potentially causing eye injury in close proximity attacks. The sudden loss of vision from a laser illumination is disorienting and debilitating, and the fear of injury is real, yet typical safety glasses provide no protection from these threats.
NoIR GlareShields™ eliminate the disabling effects of a laser attack and reduce the risk of eye injury without compromising mission performance. The ARG and CC1 filters protect against Green and Blue laser threats (FAA data on laser strikes against aircraft report 87.2% green, 8.2% blue) and the CC2 filter protects against Blue, Green and Red lasers. GlareShields™ are optimized for nightime, offer Z87.1 impact and 100% UV protection, and allow visibility of the beam (for point source location).
NoIR GlareShields™ laser pointer filters provide necessary and sufficient protection from the disabling effects of intentional or incidental laser pointer hits without compromising the wearer’s ability to perform on the job. All NoIR GlareShields™ provide full daylight UV and glare protection along with laser safety. But since the flash-blindness effect of a laser pointer illumination is much more pronounced at night when the lasers are brighter and the eye is dark acclimated, NoIR offers a line of GlareShields™ designed for use in low light/nighttime conditions. GlareShields™ optimize protection from the beam with Optical Densities (ODs) between 1-3 (absorbing 90-99.9% of the beam energy), while in some cases still allowing visibility of the beam spot without compromising visual acuity or display panel color recognition (for point source location and perpetrator apprehension), and for close exposure crowd control ground exposures, higher to full protection against the laser illumination.
Developed in cooperation with the LAPD Air Support Division, NoIR GlareShield™ laser filters for pilots provide protection from the disabling effects of a laser attack and reduce the risk of eye injury, all without compromising display and instrument panel color recognition.
While no accidents have been attributed to laser illuminations, there is the potential for an accident. "Sudden exposure to laser radiation during a critical phase of flight, such as on approach to landing or departure, can distract or disorient a pilot and cause temporary visual impairment," the report stated. Helicopters, especially those used by law enforcement, are at a greater risk, since they often hover at low altitudes and can be more easily targeted.
The hazard is significant: A 5-milliwatt green laser -- the maximum output for any device labeled and sold as an office laser pointer -- is a distraction to pilots over a mile away, while a 125-milliwatt laser can cause a cockpit distraction at a distance of greater than 5 miles. The danger posed by a bright laser illumination is increased at night, as the target’s eyes are low-light adapted and the effect is more pronounced. Standard sunglasses typically afford no protection from high-intensity green, blue and red laser pointers; in fact, normal sunglasses can have the undesired effect of increasing the time it takes to adapt to the bright glare of a laser illumination.
Ground based law enforcement officers are also at risk of laser illuminations, and GlareShields™ are designed to reduce the hazard of a laser pointer illumination to these personnel, ensuring the wearer is protected and still at peak performance.
