  • Blue Lasers

    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. 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 pointer is now the world's most popular laser pointer, 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 pointer 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 pointer was released in the early 1980s. The first red lasers Nowadays, the more durable transmitted red light air, dust, water vapor, so the light path can be seen to need more power. 100mW red light probably only about 20 milliwatts green light. But 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 red 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 red 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.

  • Burning Lasers

    Burning laser pointer are becoming more and more popular, from the original blue, to the green and red. There are 146 more on our website at present. With lasers now able to reach speeds of up to 5,000mW or 5 watts that can be used for a variety of tasks. It can be used for cutting, welding, and drilling. It can also be used for engraving and marking. This beam of light can be used to burn through many materials, including tires. it is critical to understand where the burning limit is and to keep it at a minimum of 100mW as a general rule. 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 Lasers

    High power laser pointer have been favored in laser pointers market and are increasingly popular among enthusiasts. Most of powerful 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 high powered lasers, causing discomfort and injury. We develop more and more high power lasers for you.

  • Place to Note

    Now, more and more laser pointer and flashlights sold in the market are class IIIB with a power over 5mW. But when the light directly penetrates into the eyes, there may be some damage. Especially to some high power, diffuse light probably damage the eyes, the focus are more likely to ignite flammable materials. The eye is of prime interest for two reasons: Firstly, the eye is the only organ of the body that allows optical radiations, from 400 to 1400 nm, to penetrate deep within it. Secondly, the refractive properties of the cornea and lens result in an increase in irradiance (W/cm2). If sufficient energy falls upon the retina to produce irreversible damage then such damage may occur as a result of one of three primary damage mechanisms. Therefore laser pointers are not a toy, not suitable for kids. When operating powerful light pointer, wear special secure glasses would be safe, especially for the invisible lights.

Very impressed! Was looking for a fun laser pointer like we used to have when I was younger to use outside. This laser pointer is so powerful! We literally pointed it a mile down the road at night and could see it clear as day with no fading! You can point at specific stars and can see the entire beam and looks as if it is touching the star itself.
