Abstract

The utility model discloses an attachment lens for multi-image photography. A spectacle group is arranged in front of the camera lens, the specular surface is inclinedly corresponding to the camera lens, and the other spectacle group is correspondingly offset at the other side of the spectacle group. The specular surfaces of the two spectacle groups are mutually inclined corresponding, at least one spectacle group is composed of more than two crossing flat reflectors, and the range of the included angle of the crossing specular surfaces is 150 DEG-180 DEG. The photographed objected can form a plurality of images on the camera negative film via the attachment lens for multi-image photography, and the photo can be got through one-time exposing. The utility model has the advantages of simple structure, convenient operation, low cost and easy popularization.

Description

Attachment lens for multi-image photography

A kind of double image photography auxiliary lens is applicable to the double image photography to object, is particularly useful for professional photographer's carries out disposable a plurality of imagings to people or thing photography.

Existing double image photography auxiliary lens mainly contains two kinds, the one, before camera lens, install the lens type auxiliary lens additional, occurring the picture of a plurality of same objects on the camera and on egative film, obtaining because the effect of prism makes by single exposure, but this auxiliary lens is the refraction by optical path prism obtains a plurality of images, thereby on the egative film of camera, there is a bigger aberration, and under the normal optical illumination, be difficult to obtain consistent clear photograph.Another kind is to be replaced the object lens on the camera and be contained on the camera using by many set of shots, like this, each independent camera lens all can become a picture on the certain position of camera, obtain the effect of the many pictures of a thing by single exposure, but this compound lens complex structure, the cost height is difficult to penetration and promotion.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned existence, to provide a kind of simple in structure, easy to use, and cost is low, is easy to a kind of double image photography auxiliary lens of penetration and promotion.

The utility model is achieved by the following technical solution, promptly adopting plane mirror is totally two groups on double image camera lens, one group of the place ahead that is arranged on camera lens, minute surface is tiltedly to camera lens, another group is biased in last group opposite side corresponding to camera lens, the minute surface of two set of contact lenses is tiltedly right mutually, and having at least a lens set to be intersected by the plane reflection eyeglass more than two forms, angular range between two minute surfaces is at 150 °-180 °, make object image on the visual field of camera lens through first set of contact lenses, if all being intersected by the plane mirror more than two at least, two lens set form, install the position of two lens set so, is not as the criterion on same plane with two intersecting lenses.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an embodiment synoptic diagram of the present utility model.

Below will the utility model is further introduced by accompanying drawing.Fig. 1, lens set 1 is intersected by two plane mirrors to be formed, it vertically is placed in angle α=171.2 of two minute surfaces ° on the base 3, and make its minute surface tiltedly to camera lens 4, camera 5 is placed on the support hole 6 of base 3 by the screw of bottom, on the opposite side base of lens set 1, be fixed with the lens set 2 that intersects combination by other two plane mirrors corresponding to camera 5 with fixed mount 7, fixed mount 7 is 138 ° with the angle of base 3, angle β=174 of two minute surfaces °, and lens set 1 is orthogonal with the eyeglass intersecting lens of lens set 2, the minute surface of lens set 2 is tiltedly to lens set 1, respectively is in the both sides of the angular bisector of lens set 1 with camera 5; Also be provided with bracket holes 8 on the base 3, during use, lay and be fixed on base 3 on the support, subject is put in the place ahead of lens set 2 one side, make itself and lens set 1 respectively in the both sides of the angular bisector position of lens set 2, two pictures that subject is become by lens set 2 are adjusted the focal length of camera lens 3 again through 1 one-tenth four picture of lens set and drop in the visual field of camera lens 3, can obtain four images clearly by single exposure on egative film.

Fig. 2 has described an embodiment of the present utility model, four images for the same object that on the camera egative film, obtains varying in size, can before and after two catoptrons of lens set 2 are on aforesaid basis, arrange, i.e. reach abreast or after move wherein one and be fixed on the base 3 with fixed mount 7.

Fig. 2 has also described another embodiment of the present utility model, on the basis of Fig. 1, adds a plane mirror on the top of lens set 1, thereby can obtain the different same photo of two parts picture number up and down in camera.

The utility model compared with prior art has simple in structure, and is easy to use, and cost is low the characteristics such as to be easy to apply.

Claims

1, a kind of double image photography auxiliary lens, it is by the double image lens set being set in camera lens the place ahead and being placed on the base and constituting, it is characterized in that the double image eyeglass is a plane mirror, totally two groups, lens set 1 is arranged on the place ahead of camera lens, minute surface is tiltedly to camera lens 3, lens set 2 is biased in the opposite side of lens set 1 corresponding to camera lens 3, the minute surface of two set of contact lenses is tiltedly right mutually, and have at least a lens set to be intersected by the plane mirror more than two and form, the angular range between two minute surfaces is at 150-180 °.

2, double image as claimed in claim 1 photography auxiliary lens it is characterized in that described lens set 2 is made up of two plane reflection eyeglasses at least, and the eyeglass front and back splits.
