High-power laser Pointers have become novelty toys for many people
At present, high-power green laser pointer has become the novel toy of a lot of people. Every night, laser beams can be seen from time to time in the dark sky. But what many people don't know is that shooting a 5000MW laser pointer in an airplane's cockpit is no walk in the park. It can temporarily blind the pilot, make it difficult to land the plane safely, and put passengers and ground crew at risk. The central visual acuity of 2000mW green laser pointer decreased sharply after ignition, and the visual acuity was still declining after seeking diagnosis and treatment within three weeks. We learned this description of laser ignition from the Internet, in order to purchase this device with 1000mW transmission power and 474nm wavelength. Laser brand differentiation, each product has brand differentiation, a brand often positioning product quality, after-sales and other details also affect the price. A lot of price factors. First and second, the quality difference is the actual performance difference as the original factory, the difference of the three brands, and some other differences, such as the quality difference between the circuit configuration characteristics and the factory itself, some differences are the difference in quality control, and some differences are the brand difference. Same as any other product.

5000MW laser Pointers come in different colors, with different material costs and technology costs. Even if the performance is the same. Like 2 kg watermelon, a variety of yellow meat and red meat watermelon prices. Although the color is same, laser power is same, also can be different because of design, material grade, do the work is different, the price is different also. In the past year alone, the Federal Aviation office has received 322 attacks on German airlines' planes and helicopters, most of them in Germany's 5km Green high powered laser, the newspaper reported. There were still 342 laser attacks in 2012, but only 279 in 2011. Pilots sometimes have to seek eye treatment afterwards, according to the Federal Aviation Office. I absolutely can't understand it. How do you keep the 200MW laser designator so you can intelligently dazzle pilots? Also, the beam scatters farther, so you have to get closer to really get a good light output into the eye. This means that the personnel have to be very close to the aircraft -- so the aircraft has to be stationary, which is usually a safe position to be in, whether it's blind or not.
