The wavelength of light emitted by the green pen is 532nm, the laser type is Class IIIA, and it uses two no.7 batteries. The brightness of the green pen is objective, so the risk to the eyes is relatively high, the higher the power, the more dangerous. In general, 5MW laser Pointers are commonly used, and the US market allows 5MW laser Pointers, with more than 5MW required through special approval. In China, there are no strict restrictions, which requires us users to pay special attention to safety, not to the eyes or other vulnerable parts, but also to prevent laser reflection into the eyes. Laser manufacturing technology is easy to operate, non-contact, high flexibility, high efficiency, high quality, energy conservation and environmental protection outstanding advantages, such as cutting, welding, surface treatment is the mainstream of the complex components, high performance manufacturing and precision manufacturing method, known as the "universal machining tools" and "future manufacturing system general processing method", which stimulates the development of the advanced manufacturing industry, It has a profound influence on the process of industrial intelligence.
We've seen how invisible or infrared high powered laser beams can be used, but what about visible colors like green 532nm? The short answer is yes. Use visible colors such as green, red, blue, or even purple/purple. The most common visible colors are green and red for several key reasons. First, a green laser with the same power is five to seven times brighter than any other color. As a result, you can get greater visibility at the same power level and lower power consumption. This gives the ground crew more time to use the laser after a single charge. This is essential for completing a mission or exercise. A 200mW green laser beam is 5 times brighter than a 200mW red beam and a 200mW purple laser is 7X brighter. This is something the military keeps in mind when choosing the right model for any training or actual exercise.
Canada geese and other birds are protected wildlife species. They're migratory animals, and they form the classic "flight-V" that we're all familiar with and have seen in classic movies like The Big Duck. Many homeowners, golf courses, parks and areas near water are bombed every year. They cover large areas and can come in groups of up to three to 100 people. This means chaos around your lawn and field. When the geese are fed, they also defecate around the house.
