You can use them for extensive purposes like pointing at desired targets on presentation slides, video monitors, projection screens, forensics, star pointing, astronomical uses, tour guides, construction inspections, torchlight, etc.

Laser light pointer

Blue Laser pointer with 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 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 nm, 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 mw green lasers are commonly used in astronomy is because of its visibility.

Red Laser Pointer.

A laser pointer or laser pen is a small handheld device with a power source usually a battery and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a clean atmosphere, only showing a point of light when striking an opaque surface. Laser pointers can project a visible beam via scattering from dust particles or water droplets along the beam path. Higher-power and higher-frequency green or blue lasers may produce a beam visible even in clean air because of Rayleigh scattering from air molecules, especially when viewed in moderately-to-dimly lit conditions. The intensity of such scattering increases when these beams are viewed from angles near the beam axis. Such pointers, particularly in the green-light output range, are used as astronomical object pointers for teaching purposes.

Laser pointers make a potent signaling tool, even in daylight, and are able to produce a bright signal for potential search and rescue vehicles using an inexpensive, small and lightweight device of the type that could be routinely carried in an emergency kit. There are significant safety concerns with the use of laser pointers.
