Laser protection for pilots and military personnel
17 February 2016
Worldwide aviation officials and agencies are recording dramatic increases in malicious and inadvertent laser strikes on commercial airlines.
Now, the US military protective equipment manufacturer, Revision Military
has developed and patented a laser dye for a dual-band laser protective lens that blocks 99.9 percent of green laser energy and over 99 percent of the most powerful Near-Infrared (NIR) component of commercially available green lasers
Revision's patented dye is used in the company's new LazrBloc GF-8 Laser Protective Ballistic Lens, which blocks green laser emissions and the high-risk NIR energy that exists outside the visible spectrum. Revision says its new lens delivers greater visible light transmission and colour recognition when compared with other laser lenses on the market, making GF-8 lenses suitable for both day and night use.
According to the US Federal Aviation Administration, for 2015, laser strikes on commercial aircraft topped 6,624 reported incidents, up from 3,894 in 2014. The British Airline Pilots' Association has found that half of all pilots experienced a laser attack in the past 12 months. Two trends are increasingly clear: these occurrences are on the rise and are becoming more organised.
Reports indicate that illuminations by handheld lasers
are primarily green (91 percent) in colour. The wavelength of most green lasers
(532nm) is close to the eye's peak sensitivity when they are dark-adapted, and green lasers
appear brighter than other laser colours of equal power output. Inexpensive and easy to obtain laser devices may not filter and/or align the optics, or can be maliciously altered, contaminating the green laser with a potentially harmful NIR component at 808nm.
Revision says its LazrBloc GF-8 laser protective lenses are designed to block this NIR wavelength, which is undetectable by the naked eye, while still maintaining superior light transmission, colour recognition, and situational awareness as compared to other dye-based laser lenses.
