More, if friends need to buy laser equipment, we must choose to choose regular manufacturers
In fact, the inner core fiber is a transparent optical glass with high refractive index, and the outside wrapping layer is made of glass or plastic with low refractive index. This structure can make a light along the inner core index forward, like the water in the tap water pipe in the forward flow of electricity in the wire transmission forward, even thousands of around 100 fold not what effect. On the other hand, wrapping layer of low refractive index and can prevent light leakage, like water is not water seepage, the wire insulation layer is not conductive.
o how to transfer the laser? We know that electricity is transported along the wire, but the light is not along the common metal transmission line. Therefore, scientists have developed a transmission optical filaments, called optical fiber, short fiber. The fiber is made of special glass materials, the diameter is thinner than a human hair, usually 50 to 150 microns, and is very soft.
With the light transmission of information, is very common in today. For example, with communication signals of ship, red, yellow and green traffic lights scheduling. But all these information with ordinary light, are confined within a short distance. To get information through the light transmitted directly to the distant place, you can not use ordinary light, and can use the laser.
