Abstract
The utility model discloses a portable lens formula optical collimator, including screw connector, tail optical fiber, lens adjustment tank, self -focusing lens, screw connector end connection integral type body, the installation of integral type body second half section the tail optical fiber, the tail optical fiber tip is installed in the tail optical fiber locator, half section preceding installation of integral type body self -focusing lens, self -focusing lens installs at the top regulation handle, it installs to adjust the handle inside the lens adjustment tank. Beneficial effect lies in: easy operation, the position that need not to remove the collimater when corresponding different light signal, it can only to need to remove lens.
Description
Technical field
This utility model belongs to fibre optic transmission equipment field, is specifically related to a kind of movable lens formula optical fiber collimator.
Background technology
Optical fiber collimator is mainly accurately positioned by tail optical fiber and GRIN Lens and forms, transmission light in optical fiber can be transformed into quasi-parallel light by it, or external world's directional light is coupled in single-mode fiber, it is mainly used in inside the devices such as circulator, photoswitch, collimator array, mems optical switch, EPON.The ultimate principle of optical fiber collimator is, fiber end face is placed in the focal point of collimating lens, makes light beam be collimated, then slightly regulate fiber end face position near focal point, obtaining required operating distance, therefore the operating distance of collimator is relevant to the spacing L of optical fiber head and lens.So general optical fiber collimator is designed as to fix lens in the position within collimator, adapts to different optical devices by changing the position of collimator, so increase workload, it has not been convenient to operation.
Utility model content
The purpose of this utility model is that provides a kind of movable lens formula optical fiber collimator to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of movable lens formula optical fiber collimator, including screw thread coupling, tail optical fiber, lens regulating tank, GRIN Lens, described screw thread coupling end is integrally connected formula body, the described integral type body second half section installs described tail optical fiber, described tail optical fiber end is arranged in tail optical fiber localizer, described integral type body first half section installs described GRIN Lens, and described GRIN Lens top is provided with adjustment handle, and described adjustment handle is arranged on inside described lens regulating tank.
In said structure, described screw thread coupling is connected to external fiber, and optical transport enters in described tail optical fiber, when transmitting different optical signals, regulates described adjustment handle and moves along described lens regulating tank, and then regulate described GRIN Lens to adapt to unlike signal.
In order to reduce operation easier further, described screw thread coupling is connected with the engagement of described integral type body by end opens screw thread, and described tail optical fiber is regularly arranged in described integral type body second half section inside cavity in certain sequence.
In order to reduce operation easier further, described tail optical fiber localizer coordinates installation with described integral type body, and described GRIN Lens is peripheral and described integral type body matched in clearance is installed.
In order to reduce operation easier further, described adjustment handle is embedded in described GRIN Lens top by end thread, and described adjustment handle connects described GRIN Lens through described lens regulating tank.
Have the beneficial effects that: simple to operate, when corresponding different optical signal without the position of mobile collimator, it is only necessary to mobile lens.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Figure 1-Figure 2, a kind of movable lens formula optical fiber collimator, including screw thread coupling 1, tail optical fiber 2, lens regulating tank 4, GRIN Lens 7, screw thread coupling 1 end is integrally connected formula body 3, in order to hold circuit and the parts of inside, integral type body 3 second half section installs tail optical fiber 2, tail optical fiber 2 end is arranged in tail optical fiber localizer 6, in order to retrain the position of tail optical fiber 2, integral type body 3 first half section installs GRIN Lens 7, GRIN Lens 7 top is provided with adjustment handle 5, regulates handle 5 and is arranged on lens regulating tank 4 inside.
In said structure, screw thread coupling 1 is connected to external fiber, and optical transport enters in tail optical fiber 2, when transmitting different optical signals, regulates handle 5 and moves along lens regulating tank 4, and then adjustment GRIN Lens 7 adapts to unlike signal.
In order to reduce operation easier further, screw thread coupling 1 is connected with integral type body 3 engagement by end opens screw thread, tail optical fiber 2 is regularly arranged in integral type body 3 second half section inside cavity in certain sequence, tail optical fiber localizer 6 coordinates installation with integral type body 3, GRIN Lens 7 is peripheral installs with integral type body 3 matched in clearance, regulate handle 5 and be embedded in GRIN Lens 7 top by end thread, regulate handle 5 and connect GRIN Lens 7 through lens regulating tank 4.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and effect thing thereof.
