Wide variety of laser pointers
For amateur astronomers, how much electricity price must be chosen to meet the demand? Personally, I think the power of 20mW to 50mW is more suitable, and the power of 50mW feels that the conditions above the computer room are enough, especially the direct sunlight. The price of the main astronomy can be stabilized according to the bandwidth and bandwidth of the laser light, and the price is relatively expensive, but the human eye cannot distinguish the difference between the bandwidth, so economic friends decide that the power is below 50mW, which is the price, and the laser pointer below 100 yuan is more appropriate. In addition, the consumption of the generally larger laser pointer, the strongest high power laser pointer, the principle of environmental protection and cost saving, requires several good batteries. At a range between 500m and 2000m, the laser is clearly visible at night and during the day. The wavelength is 405nm and the life expectancy is 10,000 burning hours.

Nice laser pointer
I have received some nice 1000mw laser accessories. As a green laser pointer lover, I am very happy. I could have opted for the standard red laser spot, but if I change the attachment.. then something really nice comes out. For example, images of monkeys, elephants and even naked women. You can do all of this with a red light. With so many types of laser pointers, it can sometimes be difficult to decide which one is the best option. This pen is definitely a good choice. The laser pointer emits bright green light up to 8000 meters. The model of the laser gun goose is easy to hold. Also, you can attach it to your pants with a cord attached to it. The pen is also compact enough to fit in a bag. So you can use this laser pointer in any situation. At a range between 500m and 2000m, the laser is clearly visible at night and during the day. The wavelength is 405nm and the life expectancy is 10,000 burning hours.
The brightness of the starting point of the laser beam depends on the optical power of the module, the reflectivity of the surface, and the chromaticity response of the human eye. For the same optical power, green lasers appear brighter than other colors because the human eye is most sensitive to low light in the green region of the spectrum (520-570 nm wavelengths). For more red or blue wavelengths, the sensitivity decreases. The output power of a laser pointer is usually expressed in milliwatts (mW). Nice little tool for a cheap laser pointer. This is one of the best and cheapest gifts to give at a birthday or party. Also, laser pointers are easy to sell in stores or markets. These goggles are suitable for protecting your eyes when using the green laser pointer. I tested it myself with a 100mw green laser pointer.
