ProductIntroduction:

  

        Fiber collimator is a major passivedevice, it is a significant component while forming laser devices such asisolators and circulators, this kind of devices that made by precisely alignedof optical fiber tips and focusing lens. It collimates beam from fiber, or couplescollimated beams into fiber.

        According to the output mode of Optical switches,it can be classified into two categories: Non-expanded and expanded collimator.

       Non-expanded collimator consists of fiber headand focusing lens, which has simple structure, weightless and usually used inoptical fiber laser systems for beam collimate or coupling.

      Expanded collimator consists of fiber head, afocusing lens, beam expander, it has a small divergence angle and usually usedin the large spot output system.



Applications:


  ◆ Isolators

  ◆ Optical Switches

  ◆ Optical Circulators

  ◆ Fiber laser
