![]() The sensitivity to red or blue light wavelengths is reduced, so the green light appears brighter at the same power. Because the eye is most sensitive to green light with wavelength of 495-570nm. Our eyes are most sensitive to green light. The most common wavelengths are red (630 nm-670 nm), green (520 nm and 532 nm) and violet (405 nm and 445 nm). It is not only to look at the power of the lasers and the reflectivity of the surface but also the sensitivity of the human eye to color. The infrared region of the spectrum consists of radiation with wavelengths between 700 nm and 1 mm. This is the portion we call visible light. The visible region consists of radiation with wavelengths between 400 and 700 nm. Which color is the strong lasers from the green, red, blue or yellow? Ultraviolet radiation for lasers consists of wavelengths between 180 and 400 nanometers (nm). The powerful of the 10000mw lasers that application will have outstanding effects in some fields. It is no wonder that the reason why 10000mw green lasers are commonly used in astronomy is because of its visibility. 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. 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. Green is undoubtedly efficient light source, the eye more easily identified. Green pen is the wavelength of light emitted 500-550nm, the wavelength sensitivity of the coefficient table, as is the closest one wavelength. 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.
