Description
Technical Field
The utility model belongs to the technical field of fiber collimator, especially, relate to a fiber collimator's component is fixed splint in advance.
Background
The fiber collimator (fiber collimator) is formed by precisely positioning a tail fiber and a lens. It can convert the transmitted light in the fiber into collimated light (parallel light) or couple the external parallel (near parallel) light into a single-mode fiber. One is a collimator that can be in direct contact with the bare fiber. This is the cheapest and simple method, but such collimators are usually permanently attached to the fibre. Another type of fiber collimator presents a mechanical cross section with an optical connector, for example of FC or SMA type; and are not typically used for bare optical fibers. Such collimators may be easily installed or removed from the spliced fibers. The same device can also emit collimated beams into optical fibers, or for fiber-to-fiber coupling: the light exiting the first fiber is first collimated using a first collimator and then the collimated beam is focused into a second fiber using another collimator. Generally, fiber optic connectors can be viewed as a natural cross-section between fiber optics and free space optics. Another application is to combine a back mirror with additional optical elements. For example, a Faraday rotator may be inserted therein to obtain a fiber Faraday mirror, or a quarter-wave plate may be inserted therein to obtain a half-wave plate mirror. In some other cases, a fiber filter or saturable absorber may be used.
The mode that only has artifical single operation when present fiber collimator's component and optic fibre point are glued prepositioning, and this kind of operating mode is inefficient, because the less difficult operation of component size is unfavorable for reduction in production cost moreover.
