Optical element

Laser crystal rod semiconductor optical components are a kind of optical components that mature earlier and develop faster. They are simple to manufacture, low in cost, easy to mass produce, and because of their small size, light weight and long life, the variety is developing rapidly and the application range is wide. At present, there are many kinds of applications. The most important application field of optical components is Gb LAN, and optical components of 850 nm wavelength are suitable for 1Gh/. LAN, 1300nm -1550nm optical components for 1OGb LAN system [i1. The application of optical components covers the entire field of optoelectronics, has become the core technology of today's optoelectronics science. purchase large size ZnS optics components in laser ranging, laser radar, laser communication Laser analog weapons, laser warning, laser guidance tracking, ignition detonation, automatic control, and testing instruments have been widely used, forming a broad market. In 1978, optical components began to be used in fiber-optic communication systems. Optical components can be used as light sources and indicators for fiber-optic communications and as optical subsystems through large-scale integrated circuit planar processes. Due to the ultra-small, high-efficiency and high-speed operation of optical components, the development of such devices has been closely integrated with optical communication technology since the beginning, in optical communication, optical conversion, optical interconnection, parallel optical wave systems, special high precision optical lens manufacturer/supplier information processing and optical storage, optical disasters of optical computer external devices have important applications. The advent of optical components has greatly promoted the development of information optoelectronic technology. Today, it is the fastest growing and most popular in the field of optical communication. An important source of important optical fiber communication. Optical components coupled with low-loss optical fibers have had a major impact on fiber-optic communications and accelerated its development. It can be said that without the emergence of optical components, there is no current optical communication. GaAs/GaAlA. Double heterojunction optical components are important light sources for optical fiber communication and atmospheric communication. Today, all long-distance, large-capacity optical information transmission systems use distributed feedback optical components (DFB-LD). plano/spherical/aspherical/cylindrical/paraboloid/off-axis optical mirrors components are also widely used. In optical disc technology, optical disc technology is a comprehensive technology integrating computing technology, laser technology and digital communication technology. It is a high-density, fast, efficient and low-cost information storage method, which requires the beam generated by optical components. Information is written and read.
