Blue Laser pointer with 405 nanometers wavelength of light. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. It is probably not as much preferred lasers as an astronomy laser pointer, because brighter colors would make an object more visible in the sky. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard.
Green laser pointers is now the world's most popular laser pointers, because the green lasers than red lasers 6 times more than red laser beam significantly, while the price is much cheaper than the blue and yellow. Green pen is the wavelength of light emitted 500-550nm, the wavelength sensitivity of the coefficient table, as is the closest one wavelength. Green is undoubtedly efficient light source, the eye more easily identified. The green light sensitivity of the human eye is higher than a lot of red; the other is green light scattering in the atmosphere more than red light.
Red laser pointer, wavelength 630-670nm green laser pointer is more for longer. The first red lasers was released in the early 1980s. Nowadays, the More durable transmitted red light air, dust, water vapor, so the light path can be seen to need more power. 100 mW red laser pointers probably only about 20 milliwatts, and green. Do remember that red lasers are powerful since the light they emit is powerful when it hits a certain object and converges into a point.
Burning laser pointer are becoming more and more popular, from the original blue burning lasers, to the green burning lasers and red burning lasers. There are 146 more on our website at present. The shape has expanded from one to a variety of shapes, and the flashlight shape is the most. Recently, we have developed a number of Gatlin shapes, which feature good feels and textures.
High power laser have been favored in laser pointers market and are increasingly popular among laser pointers enthusiasts. Most of High power laser pointers have the function of burning, so it is necessary to pay attention to safety during use. It is necessary to wear protective glasses, which can prevent the eyes from being affected by strong light, causing discomfort and injury.
Now, more and more laser pointers and Laser flashlight sold in the market are class IIIB with a power over 5mW. But when the laser directly penetrates into the eyes, there may be some damage. Especially to some high power laser pointers, diffuse light probably damage the eyes, the focus are more likely to ignite flammable materials. Therefore laser pointers are not a toy, not suitable for children. When operating powerful laser pointer, wear special secure glasses would be safe, especially for the invisible laser.

It is my first time that I purchased such a powerful laser pen. The construction is very durable. All parts fit very securely. It is impossible to accidentally push the button. Everything about this laser is excellent and I am very happy with it. My only regret is that I was unable to get green one like this.
