Description
Technical field
It the utility model is related to detection device field, and in particular to a kind of device for detecting performance of bugeye lens, can examine
Survey the bugeye lens that field angle reaches 180 °.
Background technology
Lens optical design is a theoretical value, and eyeglass, metalwork and assembling process can all cause the mistake of lens assembling product
Difference.Even if parts are all non-defective units, the finished product being finally assembling to is also likely to be defective products, so needing the optics to finished product camera lens
Transfer performance is detected.It is projection detection that one kind is common, which to facilitate detection method, the detection method mainly by light source, graticle,
Plane receiving plane and some tool fixtures composition.Operation principle is：The light beam that light source is sent is after graticle, from camera lens most
The latter eyeglass is irradiated to first eyeglass successively, finally irradiates on the receiving surface.Wherein graticle is in the position of camera lens image planes
On, the distance of receiving plane to first eyeglass outer surface of camera lens is set according to different requirements.
For bugeye lens, the distance of receiving plane to first eyeglass outer surface of camera lens of different visual fields is different and poor
Away from larger.For field of view angle more than 180 °, the corresponding receiving plane of 180 ° of field angles to first eyeglass outer surface of camera lens
Distance is infinity, can not be detected.In addition, receiving plane is to first eyeglass outer surface of camera lens in the performance detection of on-vehicle lens
Apart from general control in 30mm or so, and for ultra-wide angle on-vehicle lens, first of receiving plane under different visual fields to camera lens
The distance difference of eyeglass outer surface is larger, is passed through for receiving plane to the distance of camera lens first surface considerably beyond 30mm, light source
Cross the imaging of graticle and camera lens on the receiving surface to thicken, it is impossible to for judging whether the imaging performance of the correspondence visual field closes
Lattice.
Utility model content
To solve the above problems, the utility model provides a kind of device for detecting performance of bugeye lens, it can be protected
The distance for demonstrate,proving field angle corresponding receiving plane to the first surface of camera lens is all 30mm, and 180 ° super wide can be reached to field angle
Angle mirror head carries out performance detection.
The technical solution adopted in the utility model is：
A kind of device for detecting performance of bugeye lens, including projector, projector's platform for placing and beam reception component,
Light source and graticle are provided with the projector, the projector is fixed on projector's platform for placing, the beam reception
Component includes receiving plane and fixed frame, and the light beam that the light source is sent is imaged on the receiving surface after graticle, tested camera lens,
The receiving plane is hemispherical receiving plane, and the hemispherical receiving plane is erect by fixed frame and fixed, in the tested camera lens
The heart is directed at the center of hemispherical receiving plane, the tested camera lens of section direction of the hemispherical receiving plane.
Further, the radius of the hemispherical receiving plane is 30mm.
Further, the center of the light source, tested camera lens and hemispherical receiving plane is respectively positioned on same straight line.
Further, the tested camera lens reaches 180 ° of bugeye lens for field angle.
The beneficial effects of the utility model are：1st, device simple structure, easily operated, uses the device detector lens performance
It is greatly improved work efficiency；When the 2nd, detecting 180 ° of bugeye lenses, the corresponding receiving plane of all field angles is to camera lens in 180 °
The distance of first eyeglass outer surface is all 30mm, and light source clearly may be used by the imaging of graticle and camera lens on the receiving surface
Distinguish, it is ensured that testing result is true and reliable.

Embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with drawings and examples further
It is described in detail, which is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
As shown in Figure 1, a kind of device for detecting performance of bugeye lens, including projector 1,6 and of projector's platform for placing
Beam reception component, is provided with light source 2 and graticle 3 in projector 1, and projector 1 is fixed on projector's platform for placing 6,
Beam reception component includes the hemispherical receiving plane 5 and fixed frame 7 that radius is 30mm, and hemispherical receiving plane 5 is perpendicular by fixed frame 7
It is vertical to fix, it is tested the center of the center alignment hemispherical receiving plane 5 of camera lens 4, the tested camera lens of section direction of hemispherical receiving plane 5
4, the center of light source 2, tested camera lens 4 and hemispherical receiving plane 5 is respectively positioned on same straight line, the light beam warp that light source 2 is sent
It is imaged after crossing graticle 3, tested camera lens 4 on hemispherical receiving plane 5.
When the utility model is used, tested camera lens 4 is placed into tested camera lens placement hole, is tested first eyeglass end of camera lens
