Blue Laser Pointer 10000mw produce radiation, more commonly referred to as light, with unique properties that distinguish laser-produced light from light from more familiar sources such as the sun or common domestic lamps. Domestic lamps emit light that is highly divergent, i.e., that spreads out almost equally in all directions from the lamp. This light has many different wavelengths (colours), which together give the characteristic colour of the lamp. In contrast, a laser produces light in a very narrow wavelength band, so narrow that the laser isreferred to as a monochromatic (one colour), or single wavelength, source. 50mw Green Laser Pointer can also produce a very narrow beam that diverges little. This low divergence means that laser light is highly directional, forming a pencil-like beam and appears as a small spot when shone onto a surface, even at distances of hundreds of metres. As a consequence, high power Green Laser Pointer 3000mw can be hazardous to the eye over considerable distances. Because laser light is monochromatic and basically low-divergent, the beam is better focused by the lens of the eye than any other light source, thus producing images on the retina with much greater intensities than is possible with domestic lamps.
On Lasers in Toys There has been significant concern that 1000mw laser pointer red are used in children's toys. Lasers in children's toys should be restricted to class 1 and class 2 laser pointers should not be sold to children.
