Abstract
The utility model relates to an auxiliary apparatus for lens imaging. During lens imaging demonstration, many students cannot see an image formed on an optical screen due to view angle restriction caused by seats. In order to solve the defect in the prior art, the utility model provides the auxiliary apparatus for lens imaging. The auxiliary apparatus is capable of reflecting the image formed on the optical screen to a camera. The technical scheme adopted to solve the technical problem in the utility model is that: the auxiliary apparatus for lens imaging is characterized in that: one end of a straight bar (1) is fixedly connected with one end of a straight tube (3) and the connection point is on the outer wall of the straight tube (3); the straight bar (1) is perpendicular to the outer wall of the straight tube (3); one opening end of the straight tube (3) is fixedly connected with a thin film (2), and the other opening end of the straight tube (3) is fixedly connected with the camera (4) for shooting the thin film (2); the camera (4) is positioned in the center of the cross section of the straight tube (3); and the axis of the straight bar (1) is coplane with the thin film (2).
Description
Technical field
The utility model relates to a kind of physical teaching aid, in particular for the teaching aid of lens imaging.
Background technology
Teacher need to be on optical bench mounted lens, candle, optical screen in order to demonstrate lens imaging, existing optical screen is the plate object that opaque material is made, so cause a problem: the angle limitations causing due to student seat, a lot of students can't see the picture that becomes on optical screen.
Utility model content
In order to solve the deficiencies in the prior art, the utility model proposes a kind of servicing unit for lens imaging, the utility model can inform camera the picture becoming on optical screen.
The utility model solves the technical scheme that its technical matters adopts: for the servicing unit of lens imaging, comprise: for connecting the straight-bar of optical bench, the straight tube that opaque material is made, the film that trnaslucent materials is made, camera, it is characterized in that: one end of straight-bar is fixedly connected with one end of straight tube, and tie point is at the outer wall of straight tube, and straight-bar is perpendicular to the outer wall of straight tube; An openend of straight tube is fixedly connected with film, and another openend of straight tube is fixedly connected with for taking the camera of film, and the position of camera is in the center of straight tube xsect, and the axis of straight-bar and film coplanar.
The utility model is that optical teaching aid proposes a kind of new technical scheme.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-straight-bar in figure, 2-film, 3-straight tube, 4-camera.
Embodiment
Below in conjunction with accompanying drawing, design and use of the present utility model are further illustrated.
Referring to accompanying drawing 1, be structural representation of the present utility model, this figure is also cross sectional representation of the present utility model.Servicing unit for lens imaging, comprise: for connecting the straight-bar 1 of optical bench, the straight tube 3 that opaque material is made, the film 2 that trnaslucent materials is made, camera 4, it is characterized in that: one end of straight-bar 1 is fixedly connected with one end of straight tube 3, and tie point is at the outer wall of straight tube 3, and straight-bar 1 is perpendicular to the outer wall of straight tube 3; An openend of straight tube 3 is fixedly connected with film 2, and another openend of straight tube 3 is fixedly connected with for taking the camera 4 of film 2, and the position of camera 4 is in the center of straight tube 3 xsects, and the axis of straight-bar 1 and film 2 coplanar.
Various equivalent modifications should be known the information of how camera being taken and play back, and such as playing with computer, such as using television for play, such as playing with projector, student just can see into the picture at film 2.
Using method: straight-bar 1 is inserted to optical bench, and imaging falls within film 2, then, camera 4 is taken.
The axis of straight-bar 1 and the coplanar reason of film 2 are: the position of being convenient to like this know film 2.Because have the scale of reflection distance on optical bench, so way is eaily: the scale position at straight-bar 1 place is exactly the position at film 2 places.
It is essential features that film 2 use trnaslucent materials are made, because all-transparent and the opaque camera 4 that all cannot allow photograph.The material of semitransparent thin film is very abundant, such as translucent polybag, and the plastic foil of trnaslucent materials etc.
The opaque reason of straight tube 3 is: do not allow indoor light affect camera imaging.
The utility model provides a kind of new technical scheme for lens imaging teaching aid field.
Claims (1)
1. for the servicing unit of lens imaging, comprise: for connecting the straight-bar (1) of optical bench, the straight tube that opaque material is made (3), the film that trnaslucent materials is made (2), camera (4), it is characterized in that: one end of straight-bar (1) is fixedly connected with one end of straight tube (3), and tie point is at the outer wall of straight tube (3), and straight-bar (1) is perpendicular to the outer wall of straight tube (3); An openend of straight tube (3) is fixedly connected with film (2), another openend of straight tube (3) is fixedly connected with the camera (4) for taking film (2), and the position of camera (4) is in the center of straight tube (3) xsect, and the axis of straight-bar (1) and film (2) coplanar.
