The laser pointer company is succeed in attracting the customer with the low cost and expense.
Laser separation technology mainly refers to the laser cutting and laser drilling technology. Separation technology is the laser energy into the tiny space, focus, get 105 ~ 1015W/cm2 high radiation power density, the energy use of this high-density non-contact, high-speed, high-precision processing methods. In such a high optical power density irradiation, almost any material, laser cutting and drilling. Laser cutting technology is to get rid of the traditional mechanical cutting, heat treatment, cutting like a new cutting method, higher cutting accuracy, lower roughness, more flexible methods of cutting and higher productivity and so on. Laser drilling method as holes in solid materials processing methods, has become an application-specific processing technology has mainly used in aviation, aerospace and microelectronics industries. The color of light from the light wavelength decision. A certain wavelength corresponding to the certain color. Solar radiation, the wavelength distribution of the visible section of the range of about 0.76 microns to 0.4 microns, the corresponding color from red to purple, a total of seven colors, the color of sunlight alone. Single-color light emission as monochromatic light source that emits a single wavelength of light. The customer is very satisfied with the low cost and expense of laser pointer .
Such as krypton lights, helium lights, neon, hydrogen lights are monochromatic light sources, only a certain color of light emission. Although monochromatic single wavelength light source, but there is still a certain distribution. If only transmit red neon, color is very good, known as the highest monochromatic wavelength range of the distribution is still 0.00001 nm, so the neon red light, if carefully identified dozens of red still contains . Thus, the optical radiation of wavelength range of the more narrow distribution, the better the color. Output of the laser light, the wavelength distribution is very narrow, so very pure color. The output of red helium-neon laser, for example, the wavelength of the light distribution can be narrow to 2 × 10 ^ -9 nm krypton lamp emits a red light wavelength distribution of the two ten thousandths. Thus, the laser is far more than any kind of monochromatic light source. The price difference of laser pointer is little actually.
This kind of laser pointer has no directivity. Laser treatment of myopia safe? Rapid development in medical technology today, laser treatment of myopia has become a major weapon, of course, security has also been widespread concern in the majority of patients with myopia.
