military laser pointer blue light powerful burning
What is the danger of a laser pointer?
In the case of people, the 100mW has been reported by the media to produce light from the laser pointer to temporarily blind an exhibition. As for the flash of the camera, the reason for the brief exposure to the laser, now, in retrospect, the seller's green laser 3000-megawatt is so powerful, it can interfere with sight, especially when darkness or night falls. In addition, trying to get out of a laser beam could put exposed people at risk. Red laser, 100MW. For example, the driver could lose his vehicle and try to avoid the red 100 megawatt control of a possible retinal burn laser that can be so powerful that it can occur after exposure to the laser beam. Calculations show that if exposure lasts more than 100 seconds, retinal damage can be detected. This means that a full extension look together in the radius of this period of time to deliberate construction laser pointer media reports, most of the events involved in brief exposure to laser "flash". In this case, there may be visual discomfort and visual effects; However, there should be no permanent damage to the retina.
The laser pen is said to light the match. This is true, but not all cheap laser Pointers. We know that power is a key factor affecting lasers. In this way, high-power lasers have functions, usually at more than 200 mw. If you're an astronomer, the green laser has a lot of power with you. It's better when you click on the star. As long as the technology develops, its function is increasing. The first generation is a unique laser pointer that does not emit laser points. The second generation has electronic functions on the basis of the first generation. A typical product is a projection laser that can flip a page. The latest generation is technological breakthroughs and innovations.Remember, if you plan to use it in the classroom or business management meeting, please choose the . Not only can he turn pages, he can also write and use a computer on a computer screen. Now that you know the different types of laser pointer, please consider you going to use the location of the indicator, and used according to your need to decide which type of laser pointer.
Try a laser dance. Laser pointing to the pointer on the crystal, laser beam produced numerous magical dancing inches (note: dancers remember don't directly reflect the appearance of the laser beam and use only low milliwatts laser pointer).Green laser pointer is the color of choice for astronomy laser pointer, because green is the most obvious color laser pointer. Green is more apparent, because the human eye is more sensitive to green light. Another reason is that the light in the earth's atmosphere effect: when the atmospheric diffusion, can see the light in the sky, and a lower wavelength higher wavelength dispersion. Green is an average wavelength, so it's much more visible than the long wavelength of red.Do you think there's a laser pointer now?
It's still a professional with laser technology, and it's a big mission to develop the latest green laser and a with high power and a variety of colors, and the most important thing to be proud of is the series of laser green tartare and developing high-output power from 300mW to 700mW. It's not the innovation and development of the laser diode technology, and while maintaining the thermostat to improve the laser diode, the laser pointer is almost impossible to maintain that high output power. In addition, the application of fresh air system, made significant breakthrough on the laser technology, make it possible to have the development of the high power green laser pen.
Teachers and teachers over the years has been using laser pointer in the process of visual presentation highlighting maps and the key areas on the screen. Recently, with the reduction of manufacturing cost consumers now have the feature of many to choose from, including different colors and styles. Laser pointer visible range can be according to the wavelength, output power and environmental factors such as background lighting and air quality and changed a lot.
For example, high power optical lasers have been used for long distance measurements. High power and low beam divergence is widely used as a small bomb target pointer of the plane. The characteristics of small Angle laser collimator fan Angle and due to its high visibility far beam and high brightness, good alignment results, makes the laser device has been applied in the battlefield. There are a number of governments that employ to show off their enemies on the battlefield. Military lasers such as high-power and portable infrared lasers are used by military soldiers to detect enemies. As a result of invisible beam projection, the pointer target on the infrared laser is used as a rifle, in order to help soldiers to realize accurate and fast target positioning and targeting. The enemy did not detect an infrared laser because of its invisible beam launch distance.
