Description
【Technical field】
Optical communication field is the utility model is related to, particularly a kind of aspherical pipe cap in optical communication field.
【Background technology】
In fiber optic communication field, the optical element such as optical transceiving device generally use globe lens and non-globe lens is as coupling
Element carries out optical focus, while also needs lens carrying out installation with supporting structure to be fixedly connected, and is consolidated with reaching mechanical location
Fixed and hermetic closed purpose.Optical window encapsulation technology plays a crucial role the normal work of photoelectric device, influences light
Window sealing technology is mainly the interconnection technique between shell and lens.With photoelectric device to the air-tightness of sealing-in component and reliably
Property require it is higher and higher, frequently with the form of level Hermetic Package, to increase the long-term reliability of device.
Non-spherical lens is a kind of very important optics, and it is unrivaled good can to obtain spherical optics
Image quality, can be good at correcting a variety of aberrations in optical system, improves image quality, improve system distinguishing ability, it
The optical system that multiple sphere devices can be replaced to form with one or several aspheric surfaces, so as to simplify apparatus structure, reduces
Cost and the instruments weight that effectively mitigates.
Although non-spherical lens has a bright prospects, the approximate curvature radius of the aspheric component of non-spherical lens relative to
Its smaller surface of land portions radius it is more convex or more recessed, it is this due to the limitation of aspherical mirror machining technique and detection means
The more convex either more recessed aspherical non-spherical lens for being just more difficult to process and test or even occurring designing cannot be processed or surveyed
The situation of examination, that is, allow to process such non-spherical lens and also want very expensive cost and process-cycle.
【Utility model content】
The utility model is directed to above-mentioned shortcoming of the prior art, the present invention is intended to provide a kind of aspherical pipe cap
Design, while readily can be processed and test.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of aspherical pipe cap, including non-spherical lens, metalwork；The metal piece design is pipe cap shape, metalwork
Upper end is equipped with recessed table top；The recessed table top is arranged in annulus around non-spherical lens；Molding non-spherical lens is assemblied in
The centre position of metalwork, pipe cap metalwork top surface centre position are a deep gouge, and the perforate of deep gouge centre position is described aspherical
Mirror is in contact with the side wall of metalwork；The non-spherical lens bottom is arranged on inside metalwork perforate；The non-spherical lens
Upper end is exposed to pipe cap outer end.
Further, molding non-spherical lens is integrally formed with metalwork.
Further, the non-spherical lens includes being surrounded by method with non-spherical lens bottom at the top of non-spherical lens
It is blue.
Compared with prior art, the utility model has the advantages that：The coefficient of expansion and metalwork of glass material
It is close, it is ensured that when expanding with heat and contract with cold, non-spherical lens does not produce rupture；The perforate of top surface centre position is to reach guide-lighting effect.
【Brief description of the drawings】Fig. 1 is the structure diagram that the utility model microballoon pipe cap sinters gauge.
1- metalworks, 2- non-spherical lenses, 3- metalwork madial walls, 4- non-spherical lenses top, 5- non-spherical lenses bottom
Portion.
【Embodiment】
To make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1,
A kind of aspherical pipe cap, including non-spherical lens 2, metalwork 1, metalwork 1 are designed as pipe cap shape, metalwork 1
Upper end is equipped with recessed table top 3；The recessed table top 3 is arranged in annulus around non-spherical lens 2；In the recessed table top 3
Between position perforate；Molding non-spherical lens 2 is assemblied in the centre position of metalwork 1, the non-spherical lens 2 and metalwork 1
Side wall 3 is in contact；2 bottom of non-spherical lens is arranged on inside 1 perforate of metalwork；The non-spherical lens upper end 4 exposes
In pipe cap outer end；The non-spherical lens bottom 5 is in inside pipe cap.
Wherein, molding non-spherical lens 2 is integrally formed with metalwork 1.
The advantages of basic principle and main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
