Normal operation of the laser pointer beam
The producers of the laser show have not had an accident in 20 years. They used the latest technology, such as software beam attenuation maps for audience beams. The laser output power was calculated to be within the acceptable range for this type of performance. 10000mw blue laser, the laser beam was tracked and operated normally (hence safe) on both nights. This is an extra protection we encourage you to use, especially for lasers with power greater than 5mW. For example: 3000mw green laser pointer. Operating capacity up to DC3volts. The optimal temperature is 0-35 degrees. Its size: 13mm*147mm. Its weight is: 46g (without battery). It has a point light source with a fixed focus. In short, this laser pointer is a great choice.

Laser pointers are widely used in the crowd
In contrast, laser pointers are widely used in the crowd. The irradiance of a 200mW laser pointer is 1,020mW/cm2 at a distance of 3 meters, which is 20 to 100 times that of a laser emitting laser.
- 1. Green light laser pointer, laser demonstration is used in teaching, teaching is a modern mold and equipment, teaching laser pointer is the third generation of writable laser pointer, teachers, trainers, speakers, faculty members make demonstrations and demonstrations Project, the two are so embarrassing that they can be triggered at the touch of a button. On the one hand, it is very convenient to explain the operation on the computer side. The restrictions on actions are still very convenient.
- Astronomical laser pointers can also be misused to provide longer exposure times than laser display lasers. It requires 2 AAA batteries. Wavelength 532NM, 3B class high power laser pointer, range 8000-10000km. The higher its power, the farther it will affect.
In addition, the laser pointer generally consumes a lot, and it is also necessary to match a pair of good rechargeable batteries in accordance with the principles of environmental protection and cost saving. At present, the electricity price of 50mw green laser is not expensive, only slightly higher than that of 200mw laser. The price of the main 5000mw green laser pointer is related to the narrow bandwidth of bandwidth and stability. The price is relatively expensive, but the human eye cannot distinguish the difference in this bandwidth. Therefore, friends who are more economical choose the power below 50mW and the price of the laser pointer. Below 100 yuan is more suitable. In addition, the laser pointer generally consumes a lot, and it is also necessary to match a pair of good rechargeable batteries based on the principles of environmental protection and cost saving. At present, the electricity price of 50mw green laser is not expensive, only slightly higher than that of 200mw laser.
