Heart as a indispensable part of the body, support the body's metabolism.
There is no doubt that the laser as a light heart, is also the most sophisticated parts, and support the work of the entire drive operation.
Today let's solve the mysteries of laser unknown, explore interesting laser principle.
one, part of the laser head
laser is mainly composed of laser generator ( Is also called secondary laser light) , half reflective prism, lens, lens and photoelectric diode these parts.
2, the working mechanism of the laser head
laser head to move in the Table - by the center 的- - - - - - Contents, by emitting laser to find the location on the disk, induced resistance to accept to the reflected signal output into electronic data. When laser reads the data on the disc, the laser light from a laser generator through half reflecting prism, converge on the objective lens, lens will become extremely tiny points of light and laser focus on CDS. At this point, the reflection on the disc material will go back to light reflection, through the objective lens, then illuminate on half reflecting prism. At this time, because of the prism is half reflection configuration, so you don't let the beam right through it and back to the laser generator, but after reflection, through the lens, reached the photodiode. Due to the disc surface bulging is uneven point to record the data, so the reflected light will be headed in different directions. People at different directions of signal is defined as & other; 0' Or & other; 1' And light-emitting diodes (leds) are those who get to & other; 0' ，“ 1' Arrangement of data, and ultimately will parse them into the data we need.
3, the maintenance of the laser
laser is the heart of the optical drive, mainly be responsible for the work of reading data, so take special care when cleaning drives internal. Laser protection solder short, blowing balloons with small hair brush with clear the dust on the surface of the laser clean, with a toothbrush under running water will clear out the buffer the grease on the rack. Then put the laser in cleaning tank filled with water, into one or two drops of detergent. Let stand for 10 minutes after cleaning machine power and press the cleaning to switch, and then take out the inside of the dry sewage, the last is to remove baldheaded internal moisture, after the above steps to deal with the surface of the laser head if brightness is new, the objective has become transparent blue.
the development of laser technology to restrict the further development of digital optical disc and we technology. Because the laser technology in our country is relatively backward compared with advanced foreign technology, so the research of laser technology and optical fiber laser cutting machine has very important practical significance. Laser equipment factory as laser industry leader in China, the research on the techniques of laser furnace pure blue flowers, and keep head on and on, unlimited power for the development of laser technology.
China laser equipment factory is a professional laser equipment manufacturers and 2000 w fiber laser cutting machine manufacturers, our products are laser marking machine, laser engraving machine, etc.
