The fixing structure adopts the sleeve to fix micro optical elements, the through hole is formed on the side surface of the sleeve via laser, and the colloid is injected into the through hole for bonding and fixing the optical elements. The fixing structure is simple and solid in structure and convenient in operation, is not easy to cause pollution to the optical end surface, and has good temperature stability.
Description
Technical field
The utility model relates to optics or optical-fibre communications field, relates in particular to a kind of optical elements immobilizing structure.
Background technology
In optical module or instrument, to be fixed optical device, when needs are placed on optical element in the sleeve and fixedly the time, traditional way is that optical cement is coated in the side (obstructed light part) at optical element, and then slowly push need optical element to fixing position, or coat first optical cement at the relative position of sleeve, and then push element to installation site, re-use at last ultra-violet curing.No matter be the former or the latter, operating must be meticulous, optical element is being pushed in the process of position, the meeting that is difficult to avoid is seeped into optical cement the pollution that causes on the element end face element, greatly reduce its optical property, and in the process of ultra-violet curing optical cement, ultraviolet light can impinge upon on the optical element for a long time, also can reduce its performance.In addition, to optical element small optical element particularly, can be a very thing of trouble at its side gluing, take time and effort, so need a kind of method of improvement to make fixation procedure simple to operation.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of optical elements immobilizing structure, easy and simple to handle, be difficult for causing the optical side surface pollution.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of optical elements immobilizing structure, comprise a sleeve, and described cartridges sides is provided with through hole, is marked with colloid in the through hole.
Further, described through hole is cylindricality clear opening, stepped ramp type through hole or conical through-hole.
Further, described through hole number is one or more.
Further, described barrel bore shape is consistent with the optical element profile of being fixed.
Further, described barrel bore is circle, ellipse, triangle, square, rhombus or polygon etc.
Further, described colloid is the ultraviolet colloid.
The beneficial effects of the utility model are: the utility model adopts fixedly minute optical element of sleeve, and get through hole in cartridges sides by laser, in through hole, inject colloid bonding fixing optical element, simple in structure, firm, easy to operate, be difficult for causing the optical side surface pollution, and have good temperature stability.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The utility model adopts fixedly minute optical element of sleeve, and gets through hole in cartridges sides by laser, injects colloid bonding fixing optical element in through hole.Concrete, shown in Fig. 1-5, optical elements immobilizing structure of the present utility model comprises a sleeve 1, sleeve 1 side is provided with through hole 101, is marked with colloid 2 in the through hole 101.First optical element 3 is inserted in the sleeve 1, and be adjusted to through hole 101 positions, optical element 3 sides (non-logical light face) are on through hole 101 ports, at through hole 101 interior injection colloids 2, the side of optical element 3 just with colloid 2 close contacts, it is just that optical element 3 is fixing after colloid 2 solidifies, can not produce with sleeve 1 and relatively move, and colloid 2 can not pollute the logical light end face of optical element 3 yet, this is simple in structure, firm, easy to operate, have simultaneously good temperature stability.
Be illustrated in figure 2 as embodiment one of the present utility model, sleeve 1 is provided with a through hole 101, and optical element 3 places in the sleeve 1, and through hole 101 ports are withstood in its side, toward through hole 101 interior injection colloids 2, such as ultraviolet glue, is cured with the ultraviolet lamp irradiation again.Ultraviolet glue colloid after the curing is just fixing with optical element 3, it can not produced with sleeve 1 relatively move.
Be illustrated in figure 3 as embodiment two of the present utility model, different from embodiment one is, relatively on the sleeve 1 be provided with two through holes 101, be in respectively on the relative two sides of optical element 3, two through hole 101 interior colloids 2 that all are injected with, simultaneously from dual-side fixing optical element 3, so that optical element 3 is more firm with the bonding of sleeve 1.
Be illustrated in figure 4 as embodiment three of the present utility model, different from embodiment one is, through hole 101 among the embodiment one is the cylindricality clear opening, and the through hole 101 among the embodiment three is the stepped ramp type through hole, the through hole port that is about to sleeve 1 outside enlarges, the injection of more convenient colloid 2 is simultaneously also further avoided colloid 2 large tracts of land to contact with optical element 3 and is caused the pollution of optical element end face.
Be illustrated in figure 5 as embodiment four of the present utility model, different from embodiment one is, through hole 101 among this embodiment is conical through-hole, through hole 101 is larger near the port in sleeve 1 outside, port near the sleeve inboard is smaller, the injection of more convenient colloid 2 is simultaneously also further avoided colloid 2 large tracts of land to contact with optical element 3 and is caused the pollution of optical element end face.
In the various embodiments described above, sleeve 1 cavity shape should be consistent with optical element 3 profiles of being fixed, such as circle, ellipse, triangle, square, rhombus or polygon etc., through hole 101 on the sleeve 1 can have one, two or more, the material of sleeve 1 can be selected metal or plastics, also can select other materials.Optical elements immobilizing structure of the present utility model can be used for fixing minute optical element such as thin lens, thick lens or other types, and the material of optical element 3 also can be the various materials such as glass or plastics.The size of through hole 101 can arrange as required, and particularly fixedly during minute optical element, clear size of opening must be also less than the thickness of optical element, can get through hole at sleeve by laser boring.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; the various variations of in the form and details the utility model being made are protection domain of the present utility model.
