Description
Technical field
The utility model is related to fiber optic communication optical devices, and in particular to a kind of collimator of micro module.
Background technology
Optical communication network is made of multiple optical devices, is increasingly popularized with the application of fiber optic network, it is also very desirable to
Further reduce the size and cost of optical device, to install optical device to high-density in a communications device.Optoisolator, light
The optical devices such as circulator, wavelength-division multiplex optical device are required for using collimator, the spontaneous size of collimator and with light device
The adjusting fixing means of part all directly influences the size of optical device, it is therefore desirable to which obtaining microminiature optical device just needs
These two aspects improves to some extent.
The adjusting fixing means of a kind of existing collimator and optical device includes optical fiber with reference to figure 1, the optical fiber collimator 1
A111, optical fiber B112, optical fiber head 12, lens 13, glass collimator casing 14, a diameter of Ф 1 of the collimator.It, will during assembling
Collimator 1 is placed in optical device casing 3 and adjusts, and collimator can be along the axially and radially adjusting of optical device casing, when optical
It is fixed on when can be optimal in collimator casing 3, bonding position is d, e position shown in FIG. 1.The collimation of collimator in this structure
Device casing 14 needs to be fixed in optical device casing 3, and a diameter of Ф 3 of optical device casing 3 is bigger than collimator diameter Ф 1.Therefore
The requirement of micro module is not achieved in optical device.
The adjusting fixing means of existing another kind collimator and optical device is with reference to figure 2, including optical fiber head 12, optical fiber
A111, optical fiber B112, lens 13, optical device casing 2.Collimator does not use collimator casing in this structure, but will be saturating
Mirror 13 is directly fixed in optical device casing 2, therefore the diameter Ф 2 of optical device casing 2 more direct than the optical device casing 3 in Fig. 1
Ф 3 is small, can reach the requirement of microminiature optical device.But in this structure, lens 13 will be first fixed in optical device casing 2,
Fixed position is g positions shown in Fig. 2, then adjusts optical property, optical fiber head 12 and lens 13 by adjusting optical fiber head 12
Bonding position be f positions shown in Fig. 2.Since lens 13 are first fixed, it is impossible to it is adjusted axially, it can only be in radiai adjustment optical fiber
Head, therefore optical property can be impacted, and lens 13 and optical fiber head 12 only by gluing together, no collimator casing is fixed,
It causes structural instability and sealing performance is bad.
Therefore, the utility model provides a kind of collimator of micro module, can reach the requirement of micro module
The stabilization and leakproofness of good optical property and structure can be met.
Utility model content
The purpose of this utility model is to provide a kind of collimators of micro module, can reach wanting for micro module
The stabilization and leakproofness of good optical property and structure can also be met by asking.
To achieve these goals, the technical solution that the utility model is taken is as follows：
A kind of collimator of micro module, including collimator casing, one end-face is for the end with optical device casing
Face is bonded；Lens, part of it are located in collimator casing, and another part is located in optical device casing, are equipped on the outside of lens viscous
Position is connect for Nian Jie with optical device internal surface of sleeve pipe；Optical fiber head, in collimator casing, the end face of the optical fiber of optical fiber head is to saturating
Mirror.
As a kind of preferred embodiment, the optical device casing that above-mentioned collimator casing is used for outer diameter is Ф 2 is Nian Jie, collimator
The internal diameter of casing is Ф 1.
The utility model compared with prior art, possesses advantages below：
Which solve two kinds of Fig. 1 and Fig. 2 in the prior art collimator the shortcomings that so that this result can reach extra small device
Standard, while lens can reach better optical property axially and radially rotating adjustment.
The collimator of micro module provided by the invention, use existing collimators a large amount of on the market optical fiber head and thoroughly
In the case of mirror, substantially reduce the diameter of optical device casing, reduce the volume of optical device, can be widely used for optoisolator,
The microminiatures optical device such as optical circulator, wavelength division multiplexer, collimator need not in addition individually using existing lens and optical fiber head
Customization reduces cost.

Specific embodiment
The purpose of the utility model is to overcome the defects of the prior art, providing a kind of collimator of micro module, under
Face is in conjunction with the embodiments described in further detail the utility model.
Embodiment
As shown in figure 3, a kind of collimator of micro module, including optical fiber head 12, optical fiber A111, optical fiber B112, lens
13rd, collimator casing 14.
The internal diameter of above-mentioned collimator casing 14 is Ф 1, and the outer diameter of optical device casing 2 is Ф 2.From a left side in collimator casing 14
Optical fiber head 12, lens 13 are equipped with successively to right.Optical fiber head 12 is optical fiber A111, optical fiber B112 and the glued composition of optical fiber capillaries.
The end face of optical fiber A111 and optical fiber B112 are towards the focus of lens 13.
13 sub-fraction of lens is located in collimator casing 14, another to be predominantly located in optical device casing 2, convenient in light
It is adjusted in device casing 2.
One end that the collimator casing 14 has lens 13 is for the bonding end face be bonded with optical device, and bonding end face is set
