  • Blue Lasers

    Laser pointers with 405 nanometers wavelength of light  are also called blue laser pointers. 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. Although high powered lasers are becoming more popular, very few people are aware of their applications. Blue lasers are best tool in astronomy as they can be used to better focus miles into the night sky. It is now easier to point stars and other celestial bodies in space with the help of this technology. It should be high power, high quality components and have out standing beam specifications. The blue lasers that you browse meet all of your expectations as well as those of the law and safety concerns.

  • Green Lasers

    Green laser pointers is now the world's most popular laser pointers, because the green light than red light 6 times more than red light 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. The uses of green high power laser pointers have become quite acceptable in astronomy not just in pointing objects but also in the processes necessary to adjust telescopes and for astrophotography. It is no wonder that the reason why 10000mw green lasers are commonly used in astronomy is because of its visibility. The powerful of the 10000mw lasers that application will have outstanding effects in some fields.

  • Red Lasers

    Red laser pointers, 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. High powered lasers can also be mounted on telescopes to help direct other people with telescopes and binoculars to An object. The lasers revolution is quickly engulfing the globe as more and more of us get our paws on these bright light pointers. It's in particular have evolved to become the example of this huge success. If you haven't seen or are not a part of this yet, you are being left in the technological stone age. It will easily be visible at night in the worst of conditions with the higher powered models even being visible during the day.

  • Place to Note
    Now, more and more laser pointers and brightest 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. In a word, no matter how much power the laser power is, you need to avoid hitting into your eyes. Today, modern technology has transformed these high powered lasers from cumbersome, convenient combustion laser pointers into palms. If you have a good understanding of burning lasers, you will know that they are powerful enough. A high power laser pointer is going to be a far more durable and practical laser module for any personal or scientific laser applications. Also, because the laser is collimated into a high output power, there is no need for any type of laser pointer modification.
