Description
Technical field
Optical field is the utility model is related to, is molded more particularly to the aspherical glass being integrally formed with becket saturating
Mirror.
Background technology
In semicon industry, the requirement to small product size is less and less, its optic path system also slowly from tradition
The lens group of cold working shifts to High-precision aspheric glass lens.The LD optical transports of especially present relatively high power, to aspheric
The requirement of the precision and profile of surface glass lens increasingly refines.Due to Conventional processing methods production glass lens its profile all
It is columned, in order to tackle its packing problem, user's generally use of high-power LD welds either trim ring or ultraviolet glue
Lens are installed into system etc. mode.This does not only exist the risk that lens come off, increases the volume of device, also affects
Heat dispersion, so as to have influence on the service life of whole device system.
Utility model content
The purpose of this utility model is to provide the aspherical glass being integrally formed with becket of a kind of delicate structure, good heat dissipation
Glass moulded lens.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of aspherical glass being integrally formed with becket
Glass moulded lens, includes the becket of convex, and the becket includes square main part and square lug boss, the master
The center in body portion is provided with a circular through hole, is provided with lens in the through hole, in the center of the through hole and the lens
The heart is overlapped, and the outer peripheral face of the inner peripheral surface of the through hole and the lens is brought into close contact, and four angles of the main part are respectively equipped with
First cambered surface, the second cambered surface, the 3rd cambered surface and the 4th cambered surface, the top of the lug boss are provided with the 5th cambered surface, first arc
Face, second cambered surface, the 3rd cambered surface, the 4th cambered surface and the 5th cambered surface are located on same circular arc, described
The center of circular arc and the center superposition of the through hole.
Further, the material of the becket is stainless steel.
Further, the length phase of first cambered surface, second cambered surface, the 3rd cambered surface and the 4th cambered surface
Deng and respectively less than described 5th cambered surface length.
Compared with prior art, the utility model is integrally formed the beneficial effect of the aspherical glass moulded lens with becket
Fruit is：By the manhole structure inside becket, the compactness that mold process lens are combined with becket is greatly strengthen,
Air-tightness and firmness are enhanced, the center that lens are designed by the cambered surface at becket edge is ensured well, together
When rubber and glass is better than due to the heat conductivility of metal, substantially increase the heat dispersion of client.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of becket in Fig. 1.
Embodiment
Fig. 1 to Fig. 2 is referred to, is integrally formed the aspherical glass moulded lens with becket, includes the metal of convex
Ring 1, becket 1 include square main part 11 and square lug boss 12, the center of main part 11 be provided with one it is circular logical
Hole 18, through hole 18 is interior to be provided with lens 2, the center of through hole 18 and the center superposition of lens 2, inner peripheral surface and the lens 2 of through hole 18
Outer peripheral face is brought into close contact, and four angles of main part 11 are respectively equipped with the first cambered surface 14, the second cambered surface 15, the 3rd cambered surface 16 and the 4th
Cambered surface 17, the top of lug boss 12 are provided with the 5th cambered surface 12, the first cambered surface 14, the second cambered surface 15, the 3rd cambered surface 16, the 4th cambered surface
17 and the 5th cambered surface 12 be located on same circular arc, the center of circular arc and the center superposition of through hole 18.First cambered surface 14, the second arc
Face 15, the equal length of the 3rd cambered surface 16 and the 4th cambered surface 17 and the respectively less than length of the 5th cambered surface 12.
First cambered surface 14, the second cambered surface 15, the 3rd cambered surface 16, the 4th cambered surface 17 and the 5th cambered surface 12 encapsulate to match TO
LD structures, simplify client installation, strengthening system compactedness.
First cambered surface 14, the second cambered surface 15, the 3rd cambered surface 16, the 4th cambered surface 17 and the 5th cambered surface 12 also cause mechanical lens
The center of axle is ensured well.Because in the process of accurate die pressing, will be needed into by the cooperation of frock clamp
The lens of type are confined in a circular rings to ensure the uniformity at two optical surface centers of lens.So as to ensure that in lens
The heart and the relative positional accuracy of each position of becket.
The inside of becket is circular through-hole structure, greatly strengthen the densification that mold process lens are combined with becket
Property, enhance air-tightness and firmness.
The material of becket is stainless steel, and each glass trade mark has its intrinsic thermal coefficient of expansion, and this is also glass
Important design driver in lens accurate die pressing technique.From possessing the thermal coefficient of expansion that matches with glass material
Stainless steel metal material is designed to becket, the assembling demand of the form fit client of its becket.Meanwhile in becket
Hole is circle.Form with becket inwall the structure of fine and close combination during hot press moulding, after Glass Transition, while in view of its
The thermal coefficient of expansion to match, shaping terminate to be maintained to the state of fine and close combination when temperature is returned to room temperature, so as to
Enhance the bond strength of glass lens and becket.Because the heat conductivility of metal is better than rubber and glass, therefore, this
Class product can greatly improve the heat dispersion of client.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
