It is the power of laser pointer which the customer asks and needs.
Can also be used to measure the distribution of clouds and reconnaissance air pollution. With a laser, a short distance terrestrial communication, confidentiality is particularly strong, difficult to be an enemy by the cut-off and interference. In addition, the high directivity of the laser can be made into a laser-guided weapons, mission rate is much higher. In building water conservancy projects, railways and roads, the need to tap the long-distance tunnel with a laser to "oriented", along the direction of the laser construction, the tunnel will be played and accurate and straight. (B) red, orange, yellow - green green violet - good color from the electromagnetic spectrum, we can see that there is a wavelength corresponds to a color. "Complex setting sun after the rain, rainbow frame the sky," This is our common natural phenomenon, because sunlight contains all wavelengths of visible light, that is, contains all the various colors in the world, the result has become white. The working personnel is responsible for the testing, detecting and commissioning total output power of laser pointer .
Therefore, the "white" light is red, orange, yellow, green, green, blue, purple variety of colors of light mixed. The smaller the wavelength range contained in a light, its color is more pure, it seems more bright, and usually we have called this high monochromaticity. The wavelength range is less than a few angstroms (1 angstrom = 1 billionth of a centimeter) section of radiation known as monochromatic light emission of the light source of monochromatic light as a monochromatic light source. And laser beam divergence angle is a measure of beam directionality is good or bad sign, line width is a measure of the monochromaticity pros and cons of standards. People in long-term production and scientific experiments, has created a lot of monochromatic light source such as a variety of neon, mercury vapor lamps, sodium lights, etc.. The personnel should increase the power of laser pointer.To ensure the good quality and performance of laser pointer
The previous best monochromatic light source is the isotope krypton lamp 86, the emitted light wavelength range at low temperatures is only about 0? 005 ? line width at room temperature for 0? 0095 angstroms, its color is very bright. The emergence of the laser monochromatic light caused a big leap. Good such as monochromatic He-Ne laser, its wavelength range is even smaller than the one ten-millionth Aye, the youngest has reached one hundred billion to a few angstroms per its monochrome than ordinary light I really do not know how many million times better . Therefore, the laser is the most pure color, color is the most fresh light. Laser such high monochromaticity What is the significance? As you know, the measurement length is very important in daily life and work. It is in accordance with some special procedures and processes of laser pointer .
