High-powered lasers are available on the internet and in stores
In various working surfaces, in order to get long term continuous dot measuring result, 650nm red laser diode module would have to be manufactured with qualified internal structure. Besides formal configuration of import 650nm red laser diode and glass cylindrical lens, this advanced dot laser alignment tool is also equipped with built-in electric driving circuit board. Comparing with formal manufactured laser modules, this advanced laser diode module always gets constant output power supply for its internal part of 650nm red laser diode.
In various kinds of industrial dot aligning works, although 650nm red laser diode module is required to make 24 hours continuous dot positioning, however, according to special configuration of built-in APC electric driving circuit, this advanced dot laser alignment tool always gets constant power supply. The special adoption of intelligent feedback electric driving circuit always ensure high stability laser dot projection, thus help users a lot for all industrial dot measuring works efficiently.
Owing to formal brightness red laser dot projection on desired working surfaces, unless sunlight working occasions, 5mW to 100mW power level red laser diode module is always making great for all working distances as expected. However, in order to get quite satisfied dot aligning result, users should be cautious enough with laser safety measures and make full control of exact work distance. Within acceptable work distance of no more than 25 meters, red alignment laser dot always keeps quite compact size. When users are making quite easy installation and adjustment of laser beam focus, this advanced laser diode module always brings users quite satisfied dot measuring efficiently.
Lasers stronger than 5mW can cause irreversible eye injury of increasing severity as the power increases. Although they are illegal, and potentially dangerous, these high-powered lasers are available on the internet and in stores. In one case, says the FDA, a child's eyes were damaged from reflected beams after directing a 150mW laser pointer into a mirror. Another child is now legally blind in both eyes after playing with his mother's laser pointer. The FDA believes that eye injuries stemming from laser pointers is under reported.
Another growing problem, says the FDA, are incidents in which pilots are experiencing temporary flash blindness when lasers are aimed at their aircraft. This temporary loss of vision can cause a serious accident. According to Federal Aviation Administration (FAA) data, between 2004 and 2006 there were about 330 cases, but since then more than 26,300 incidents have been reported.
Just in the first nine months of 2015, there have been 5,000 reported incidents.
Shining a laser at an aircraft won't get you a slap on the wrist either. It's a federal crime and those convicted face a maximum penalty of dive years in prison and a $250,000 fine. A 26-year-old California man was sentenced to 14 years in prison in 2014 for aiming a laser pointer at a police helicopter and a hospital emergency transport helicopter.
