Further, by moving up and down the prism, the relative position of the prism and variable-power optical system, energy are changed Enough change the size of two visual fields in image planes.
Further, by the way that clockwise or counterclockwise, incline of the prism at the top of it is changed the prism With the relative position of variable-power optical system, the angles of two visual fields in image planes can be changed.
Further, the angular range of two visual fields is 45 °~135 ° in the image planes.
Further, the prism uses prism of the cross section for isosceles right triangle.
Further, the bore of the variable-power optical system is D, and the right angle length of side R of the prism meets:0.5D<R<2D, The thickness L of the prism 1 meets:D<L<3D.
Further, the variable-power optical system uses 1~7 optical mirror slip.
Further, the variable-power optical system one side and close variable-power optical system side in the prism The distance between one side be arranged to 0.5~1.5mm.
Further, the camera lens one side and the one side in the variable-power optical system close to the camera lens side The distance between be arranged to 2~10mm.
Further, the zoom scope of the variable-power optical system is 0.5 times~3 times.
Due to being using above technical scheme, the beneficial effects of the utility model:The utility model is by increasing zoom light System and prism, can increase by a not coaxial shooting visual field on the premise of original system structure is not changed;This practicality is new Type can solve former camera lens image blur under some particular demands, visual angle deficiency, it is impossible to shoot clear, Quan Mianhua well The problem of face.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is a kind of structure diagram for not coaxial image optical system that one embodiment of the utility model provides.
In figure:1- prisms;2- variable-power optical systems;3- camera lenses.
Embodiment
To make the purpose of this utility model, technical solution and advantage clearer, below by the technology of the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made Obtained all other embodiment is put, belongs to the scope that the utility model is protected.
As shown in Figure 1, the utility model provides a kind of not coaxial image optical system, it includes prism 1, zoom optics System 2 and camera lens 3.Prism 1 is arranged on the front of variable-power optical system 2, and variable-power optical system 2 is arranged on the front of camera lens 3.Zoom light Relative position between system 2 and prism 1 can change as needed.Variable-power optical system 2 is set with camera lens 3 using coaxial Put.Relative position between variable-power optical system 2 and camera lens 3 immobilizes.By moving up and down prism 1, change prism 1 with The relative position of variable-power optical system 2, can change the size of the first visual field and the second visual field in image planes.By by prism 1 around Incline at the top of it clockwise or counterclockwise, changes the relative position of prism 1 and variable-power optical system 2, can change picture Angle on face between the first visual field and the second visual field, the angular range in image planes between the first visual field and the second visual field are 45 ° ~135 °.
Before variable-power optical system 2 is arranged on camera lens 3, focal length, multiplying power and the visual field of camera lens 3 can be changed.
Before prism 1 is arranged on variable-power optical system 2, by increasing capacitance it is possible to increase a visual field, by varying prism 1 and zoom optical system Relative position between system 2, can change direction and the size of shooting visual field.
