20. Competitive Price ofgreen laser pointer
Now widely used laser typesetting technology is a major revolution. Laser illumination is broken down into the text through the computer matrix, and then control the laser scanning on the photosensitive film, the lattice point of the composition with exposure text and images. Today, China has been widely used Chinese characters on the use of a laser typesetting technology typesetting, layout than the old lead type efficiency by at least 5 times. The green laser pointercompany promises that it will provide the competitive price of green laser pointer.
Photo camera lights are generally flat, with no three-dimensional. With physical terms, to get only two-dimensional image, a lot of information is lost. When the laser appears, the first time humans have been hologram. The so-called hologram is recorded all the information landscape photos. Hologram without a general camera, but rather use a laser. Laser beam with a beam splitter into two, a bunch of them shine on the scene being photographed, as the beam material; another bunch of shine directly on photographic film that is holographic plate, called the reference beam. Object beam reflected by the object, its reflection beam is irradiated on the film, the crew completed the holographic process. Hologram and the general picture different. To see with the naked eye, only some mess on the hologram stripe. The competitive price helps thegreen laser pointercompany take up more market.
But if one uses a laser to light the photo will appear in front realistic three-dimensional scene. Even more amazing is to observe from different angles, you can see different aspects of the original object. Also, if you do not accidentally hologram broken in pieces, it does not matter. Free to pick one of a small piece of debris, observed the same way, the original subject is still intact displayed. The principle is the use of holographic optical interference principle, the use of two-beam interference of light to record information on the subject. This theory has long been raised, but it requires only a laser to achieve a high degree of monochromaticity. Therefore, only after the birth of people in the laser was able to achieve that dream. The price of this kind ofgreen laser pointeris more competitive.
Another area of laser medicine flourish. It is not only in surgery can be used as a laser knife, and in ophthalmology, dentistry, dermatology and cosmetic aspects are unique applications. The beauty of laser knife cutting at the same time that it was burning, which happens to be closed vessel to prevent the bleeding, also reduces the risk of infection. Painless laser drilling of teeth and tooth decay to make people terrified of the dental surgery the previous great sense of ease. Compared to previous mechanical drilling, laser drilling is not only not have a lot of friction heat, and it just evaporated corrosion at the black teeth, healthy tooth tissue does not have an impact, so pain will be greatly reduced. The price ofgreen laser pointerprovided by thegreen laser pointercompany is very attractive.
On the application of laser in ophthalmology is the most amazing. Laser welding can be torn off the retina, leaking blood vessels closed, completely destroyed the eyes of jelly floating in the liquid in the tiny grains of sand (to gasification). The advantage of laser surgery can be done without cutting the eye surgery, and greatly ease the pain of surgery. --- For the current incurable cancer, the laser also provides an effective weapon. On the one hand, the laser can be used as a laser cutter to remove the tumor; the other hand, in the early diagnosis of cancer are also effective. The customer is satisfactory with the wholesale price ofgreen laser pointer.
