laser pointer should be kept in close and vented condition
At present, the embossed hologram as an effective means of security becomes more widely used in this area. Such as Switzerland's production of horticultural equipment RP (Ralstonpurina), U.S. production of soap, the the the detergent Procte & Gamble, the company Baer Mo production of cosmetics, Noxell Corporation, New York, the production of beauty, set hair shampoo Reylom, and a lot of production toys company Japan's Panasonic tape, Citizen watches, Zhangguang brand 101 hair regrowth essence, adopted a holographic anti-counterfeiting mark. Therefore, it is very important for the manufacturer of laser pointer .In 1988, the advent of the visible light diode lasers, providing a low cost, low-power solid-state devices. It can not only be effectively applied in the thermal printing paper and a blue and green symbols scanning, handheld bar code reading instrument miniaturization, portability has become possible. At present, visible light diode laser scanner in the world, is gradually replaced by a He-Ne laser scanner and occupy most of the bar code market. According to incomplete statistics, has now been put into use in 300,000 units visible diode laser scanner. The entire scanning system installed in a lightweight, small laser scan head. It is also important for the customer to know the real power of laser pointer .The material of laser pointer should be kept in the storage place
Is linked by cable plug, with the main computer system, its life expectancy has reached 250,000 hours, with encoding, storage, retrieval techniques together to form a laser bar code industry. Not Chen's "Reserva" housewives entertain guests often think of buying a few bottles of old wine, because in the eyes of the people, the class of the old cellar of vintage wines are wine. In fact it is the case. Because most of the wine component is water and ethanol (alcohol), in addition to esters, acids, higher alcohols, aldehydes, and other dozens of different substances. Along with the dissemination of the plume of white smoke, and diseased tissue dehydration, vaporization, and solidification. Therefore, this laser knife to remove the diseased tissue does not bleed. The carbon dioxide laser radiation penetrates tissue only 0? 1 mm deep incision side to form a narrow hot burning zone, and therefore as a "knife", it can be used for many aspects of the surgery. It is with the suitable record of laser pointer made.
The wavelength of this laser radiation in neodymium-doped yttrium aluminum garnet laser scalpel? 064 microns. Human tissue in the water on the absorptive capacity of this wavelength is relatively weak, and use it as the scalpel of the excised tissue, slightly worse effect than carbon dioxide laser. However, this wavelength of the laser beam penetrating ability, within the organization can deeply penetrate into one of the protein coagulation to achieve treatment purposes.
