Market analysis powerful green laser pointer
With the rapid development of semiconductor laser technology, low-power semiconductor lasers have achieved miniaturization. The combination of laser processing technology and micro-nano manufacturing technology realizes the large-scale production of small laser semiconductors and reduces the cost of lasers. The semiconductor semiconductor lighting represented by the pen has entered the civilian field and is widely used in fields such as astronomical observation, construction, and fire/disaster relief. Since the human eye is more sensitive to the 532nm laser, the relative contrast and damage to the human eye are better. For example, the police reduce the field of vision encountered with various Laser pointer in the process of diligence and execution, so how to protect the eyes, the green laser pointer of the eye, especially the 532nm green laser pointer, will damage the human eyes and maintain a good visual effect. Presents new challenges to the glasses industry.

The green laser pointer, because of its high power and long range, is actually hit on the wall more than five stories high, and you can see the light spot. Calculated based on the height of 5 meters, the empty bridge is about 5 floors, and it is clear if it is more than 25 meters. The pilot said that at an altitude of 2,000 feet, about 600 meters was interfered with by laser light. The laser had to shoot farther and the power would have to be higher. Li Zhexian, a laser pen manufacturer: "It should be a blue light level, because the wattage of blue light is relatively high, and it can be projected onto the cloud. Green light may not be so strong." The key is the power, the red light is low. The commercially available version has a maximum range of about 100 to 200 milliwatts, a range of about 10 meters, and is used in business presentations. Green light is stronger than red light, and the distance can be extended to 2-3 kilometers. But the real high-power is actually a blue laser pointer, more than 2 kilowatts, it can shoot 11-12 kilometers, and the heat intensity is high, and it can even burn on paper. Although it is a banned item, it can still be bought on online auctions.
