Fig. 1 shows the diagrammatic cross-section of the optical lens of the utility model one embodiment.With reference to Fig. 1, the optical frames
Head includes the first lens assembly 100, the second lens assembly 200, iris diaphgram 300 and the first glue material 400.Wherein, the first mirror
The first eyeglass group 120 that head part 100 lens barrel 110 and be mounted in the first lens barrel 110 including first, the first eyeglass group
120 include at least one first eyeglass.Second lens assembly 200 includes the second lens barrel 210 and is installed on second lens barrel 210
The second interior eyeglass group 220, the second eyeglass group 220 include at least one second eyeglass, the first eyeglass group 120 and institute
It states the second eyeglass group 220 and collectively forms imageable optical system.The iris diaphgram 300 is located at first lens assembly
Between 100 and second lens assembly 200.First glue material 400 is located at first lens assembly 100 can be changed with described
Between diaphragm 300.First glue material 400 be suitable for fix and support after hardening first lens assembly 100 and it is described can
Darkening door screen 300, so that the relative position of first lens assembly 100 and second lens assembly 200 is maintained at active school
Relative position determined by standard, wherein the active calibration is the actual imaging result based on the optical system come to described
The relative position of one lens assembly 100 and second lens assembly 200 is adjusted.Iris diaphgram 300 and second mirror
Head part 200 can be bonded together, which can complete before active calibration, can also be completed after active calibration.Under
Text can be also further described through in conjunction with other embodiments.
Further, Fig. 2 shows the schematic top plan views of the iris diaphgram in the utility model one embodiment.With reference to figure
2, which includes: that diaphragm shell 310, the drive module being contained in the diaphragm shell 310 (are not shown in attached drawing
The multiple diaphragm pieces 330 connecting out) and with the drive module.In the present embodiment, first glue material 400 is located at described
Between the top surface of diaphragm shell 310 and the bottom surface of first lens assembly 100 (as shown in Figure 1).It is practical new that Fig. 3 shows this
The schematic diagram of the change aperture of iris diaphgram in type one embodiment.With reference to Fig. 3, it can be seen that diaphragm piece 330 makes after translating
Aperture is obtained relative to stop down shown in Fig. 2.In other words, pass through the multiple diaphragm pieces 330 of translation, thus it is possible to vary aperture it is big
It is small, to realize that aperture is adjustable.In one embodiment, the size of aperture is continuously adjustable.
Although being noted that in above-described embodiment, first lens assembly 100 includes the first lens barrel 110, in this reality
It is not limited to this with novel, such as in another embodiment, the first lens barrel 110 can be cancelled, and the first eyeglass group 120 can be list
A first eyeglass, or be made of multiple the first eyeglasses for forming one and being fitted into mutually or bonding.In active calibration mistake
Cheng Zhong, when the first lens assembly has the first lens barrel, fixture (or other intake mechanisms, such as suction nozzle) can clamp (or take the photograph
Taking) the first lens barrel adjusts position and the posture of the first lens assembly, when the first lens assembly does not have the first lens barrel, fixture
(or other intake mechanisms, such as suction nozzle) can directly clamp (or intake) and form the first integrated eyeglass group, to adjust the
The position of one lens assembly and posture.
Further, referring still to Fig. 1, in one embodiment, institute is suitable for being arranged in the top surface of the diaphragm shell 310

Integrally.The assembly of the iris diaphgram 300 and second lens assembly 200 is properly termed as the second assembly.This implementation
In example, the top surface of the diaphragm shell 310 can be used as the terrace in active calibration technique and carry out multiple spot laser ranging, to know
Not Chu entire second assembly position and posture.It is (usual to the top surface of the second lens assembly due to not needing in the present embodiment
It is the top surface of the second lens barrel) multiple point distance measurement is carried out, therefore the requirement to the top planar degree of the second lens barrel, Jin Eryou can be reduced
Help reduce the height (highly referring to the size on the optical axis direction of optical lens) of the second lens assembly.As shown in Figure 1, the second mirror
The inside of cylinder has multi-stage stairs, and multiple second eyeglasses stand into the second eyeglass group by being sequentially embedded multi-stage stairs group.However, by
The top area 211 of the second lens barrel 210 is born against in the second eyeglass group 220, if the top area 211 is excessively thin, the second mirror
The top surface of cylinder 210 is easy to upturned, and carrying out multiple point distance measurement as terrace will lead to pre-determined bit inaccuracy, influences optical frames
The image quality and production yield of head.Therefore it is certain thick to usually require having for the top area 211 for ensuring the second lens barrel 210
Degree, the top surface to avoid the second lens barrel are upturned.And in the present embodiment, since the top surface using diaphragm shell is instead of second
The top surface of lens barrel can reduce the requirement to the top planar degree of the second lens barrel as terrace, so as to so that the second mirror
The top area of cylinder is thinner, and then the height for facilitating reduction optical lens or camera module (highly refers to the optical axis of optical lens
Size on direction).Herein, terrace refers to for identifying the position of the second eyeglass group by carrying out multiple point distance measurement to the face
With the structural plane of posture.The structural plane is usually flat surface, in existing active calibration technique, usually by the top of the second lens barrel
Face is as terrace.
