Abstract
The invention relates to a lens unit that is applied to an optical fiber coupling connector. The lens unit comprises a first lens, a second lens and a reflecting surface, wherein the first lens, the second lens, and the reflecting surface are integrated into one. The first lens is used for being coupled with an optical fiber of the optical fiber connector; the second lens is coupled with a photoelectric transceiving unit; and the reflecting surface is used for reflecting light emitted by the first lens to the second lens and reflecting light emitted by the second lens to the first lens. The diameter of the first lens is smaller than that of the second lens. In addition, the invention also relates to an optical fiber coupling connector with the lens unit.
Description
Technical field
The present invention is about a kind of lens unit and have the optical-fiber coupling connector of this lens unit.
Background technology
Lens unit in optical-fiber coupling connector generally comprises two groups of lens and a reflecting slant, two groups of lens are respectively optical fiber side and substrate-side, with regard to the angle of optical design, the concentric deviation of these two groups of lens is general large between several microns, so with regard to the angle of finished product, the normotopia degree of lens position is just very important, the general normotopia degree that measures lens is that the center of getting its pilot hole (post) is benchmark, then carries out the measurement of lens normotopia degree with this benchmark respectively at two groups of lens finished product faces.
With regard to measurement mode in the past, optical fiber side and substrate-side lens carry out the measurement of normotopia degree respectively at different finished product faces, although benchmark is all to capture same pilot hole (post) as measurement center, but measure and have the different problem of reference field with the method, thereby the measurement making is inaccurate.
Summary of the invention
In view of this, be necessary to provide a kind of measurement lens unit and there is the optical-fiber coupling connector of this lens unit accurately.
A kind of lens unit, for optical-fiber coupling connector, described lens unit comprises integrated first lens, the second lens and reflecting surface, described first lens be used for described optical-fiber coupling connector in optical fiber be coupled, described the second lens are used for being coupled with an optoelectronic transceiver unit, described reflecting surface is used for entering described the second lens through the light reflection of described first lens outgoing and will entering described first lens through the light reflection of described the second lens outgoing, and the diameter of described first lens is less than the diameter of described the second lens.
A kind of optical-fiber coupling connector, it comprises said lens unit.
Compared to prior art, the diameter of the first lens of the lens unit of the present embodiment is less than the diameter of the second lens, in the time observing the second lens from first lens side, the second lens can not blocked by first lens, thereby can utilize a reference field to measure the concentricity of first lens and the second lens, make to measure accurately.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
See also shown in Fig. 1 and Fig. 2, the optical-fiber coupling connector 100 that the embodiment of the present invention provides comprises lens unit 10, substrate 20 and optoelectronic transceiver unit 30.
The 3rd surface 113 that lens unit 10 has the first surface 111 that is parallel to each other and second surface 112 and intersects vertically with first surface 111 and second surface 112.On the 3rd surface 113, there is the parallel first lens of plural optical axis 11, second surface 112 has the second parallel lens 12 of plural optical axis, the number of the second lens 12 is equal and corresponding one by one with the number of first lens 11, and corresponding first lens 11 and the optical axis of the second lens 12 intersect vertically mutually.First surface 111 is recessed to form reflecting surface 13 to second surface 112, reflecting surface 13 is used for reflecting the light through first lens 11 and the second lens 12 outgoing, reflecting surface 13 and first surface 111, second surface 112 have the angle of 45 degree, so, between reflecting surface 13 and first lens 11, the second lens 12 optical axises, also there is the angle of 45 degree.Wherein, first lens 11, second lens 12 of lens unit 10 are one-body molded with reflecting surface 13.
The light that the light emitting diode of optoelectronic transceiver unit 30 sends incides on reflecting surface 13 through the second lens 12, after reflecting surface 13 is reflected, incides in first lens 11, is coupled in optical fiber after outgoing; Incide on reflecting surface 13 after first lens 11 outgoing from the light of optical fiber outgoing, be reflected after face 13 reflects and enter in the second lens 12, from the second lens 12 outgoing, received by the photoelectric detector in optoelectronic transceiver unit 30.
While measuring the concentricity of first lens 11 and the second lens 12, optical fiber not group enters first lens 11, thereby can observe first lens 11 and the second lens 12 from first lens 11 sides simultaneously.Due to the diameter of first lens 11
be less than the diameter of the second lens 12
, the second lens 12 can not blocked by first lens 11, and then can judge the concentricity between first lens 11 and the second lens 12.Because being all measures concentricity from first lens 11, adopt same reference field, thereby make to measure accurately.
Be understandable that, those skilled in the art also can do other and change in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
