Because you know that Laser pointer are used in many different applications. Therefore, there is a common rule: because the color and intensity of the laser are different, what to use depends on the purpose of use. When using traffic lights during the day, 532nm requires at least 200MW. Use laser during the day: use…

Have you ever seen a green laser pointer?
At present, laser diodes are being produced. In the context of astronomy, it is convenient to use and save space (such as battery driven handle / ordinary battery or rechargeable battery). It is recommended to use green laser radiation (better retinal stability index), which is the only color that can be completely visible to humans…
Recommendations for buying a laser pointer
Not all Laser pointer or laser manufacturers are the same. biglasers.com is a major American brand that has entered the industry since 2005, but if you own a certain laser, you must ask questions about a certain laser pointer. Due to the dangerous nature of this laser device, it must comply with the corresponding protection…
There are contradictions in the use of laser pointers
It is not a good idea to illuminate your eyes with a Laser pointer. On Saturday night, the Public Health Agency of England (PHA) called on Christmas Eve not to buy children’s homes and nursing homes because they are not toys.

Do you know how to choose different color laser pointers?
You can buy a Laser pointer arrow at the city conference, you can say there are different laser colors, a big exhibition style. -What kind of laser is that? If you don’t know what science and technology are, or what they are used for, it may be difficult for you to know which lasers are…
Why are laser Pointers strictly banned in some countries?
A laser pointer is a relatively small, invisible laser commonly used to indicate a subject of interest to a defendant in class and presentation. They’re everywhere and they’re very useful research tools in learning environments and by controlling the temperature of 1000 lasers, biological water consumption increases. By strengthening these tools, people will worry more…
Do laser Pointers really work?
At present, during the demonstration process, teachers often need to put the computer beside them, while emphasizing the operation of the computer, and occasionally stand up to show… Therefore, the expanded teaching facilities are not only underutilized, but also have an impact on traditional classroom teachers.

How powerful is the laser of the laser pointer?
Berlin-For many years, the mission of laser spacecraft to deceive pilots has been carried out all over the world. In 90% of the cases, the green wavy area uses power below the 5 millisecond pointer. Because of the lack of energy, it is difficult to…perceive the organic damage in front of your eyes. The same…
Never heard of a laser Pointers ?
In today’s situation, in order to improve the efficiency and efficiency of semiconductor chip devices, the performance of battery driven laser guns is sometimes much higher than the existing limit (model 2 or 2m laser). Short term exposure is considered harmless to the eyes. These radioactive sources are also sold as laser barriers, but the…
The development and basic principles of laser pointers
If you compare the green Laser pointer with the same powerful red laser, you will find that the green laser is about 10 times brighter. The first laser pointer used a miniaturized HeNe laser. However, only after cheap and efficient laser diodes appeared, laser pointers achieved a breakthrough in mass production. Before the advent of…
