Collimator is the optical fiber communication system is an important part of the pigtail and self focusing lens and precise positioning of the collimator is one of the most important components in passive optical devices, composed of SMF and collimating lens. What is the function of an optical collimator in practical use?

It is understood that the collimator is an important component in passive optical coupler, is widely used in optical communication system, so the collimator is the role of the beam into a parallel beam, or parallel beam to the optical fiber, with low insertion loss, high return loss, work long distance, wide bandwidth, high stability, high reliability, small divergence angle, the characteristics of small volume and light weight etc.. In addition, the optical fiber end collimator can be shot for the divergent beam transform parallel beam, or parallel beam and high efficient coupling into the fiber, is a basic device produced a variety of optical devices, so it is widely used in beam collimation, beam coupling, optical isolator, optical attenuator, optical switch, circulator, MM, dense WDM ES.

In recent years, with the development of optical communication industry, the application field of collimator is expanding, and the requirement of collimator is also improved. In some occasions, such as the miniaturization of devices, conventional optical fiber collimator is difficult to meet the requirements due to the large aperture angle of the outgoing spot.
