Abstract
The invention discloses a magnetic type material screen. The material screen comprises a material screen body, an article and a light guide member, wherein the material screen body is provided with a light hole, the article consists of an imaging article and a first lantern ring, and the imaging article is provided with a hollow imaging article pattern; the light guide member consists of a light guide piece and a second lantern ring, the material screen body is made from a ferric material, and the first lantern ring and the second lantern ring are made from magnetic materials. The magnetic type material screen provided by the invention is beneficial for the research of a lens imaging rule, and is further beneficial for the imaging quality to improve.
Description
Technical field
The present invention relates to a kind of Experiments of Optics apparatus, be specially magnetic-type thing screen for a kind of lens imaging experiment.
Background technology
In lens imaging experiment, need to provide the object for imaging.At present, the conventional candle of lighting is as imaging thing, or shields as imaging thing with the thing that Down lamp irradiates with hollow " 1 " font.With the candle of lighting, during as imaging thing, candle flame itself has instability, and with potential safety hazard, candle drop is fallen on experiment equipment and is difficult to cleaning, is difficult to the left and right position relationship of judgement picture and thing in experiment.While screen with " 1 " vee V, imaging thing shape is comparatively single.The shape of ideal image thing should have up and down, the feature of left-right asymmetry, so that the rule of clear understanding lens imaging; In addition, imaging thing should have multiple choices, and is convenient for changing in experiment.Lack at present good solution.
Summary of the invention
The object of this invention is to provide a kind of magnetic-type thing screen that is conducive to improve lens imaging experiment effect.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: a kind of magnetic-type thing screen, is characterized in that: comprise thing screen, object, light guide; Thing screen is provided with circular light hole; Object is by round-formed as thing be fixed on the collar first in imaging beyond the region of objective existence week and form, and imaging thing is provided with the imaging article pattern of hollow; Light guide is made up of circular light guide sheet and the collar second that is fixed on light guide sheet periphery; Thing screen is ferrous material, and collar first and collar second are magnetic material, and collar first is identical with the diameter of collar second, is all greater than the diameter of light hole.
Light guide sheet is pmma material.
Imaging article pattern on object is asymmetric, left-right asymmetry pattern up and down.
The present invention, owing to adopting above-mentioned design, can be adsorbed on object the light hole edge of thing screen by the collar first when experiment, the collar second of light guide is adsorbed in the collar first of object, and the object that can be used as imaging with light source irradiation light guide uses.Owing to adopting magnetic mode, in experimentation, can be adjusted at any time the orientation of picture thing, be convenient to observe the corresponding relation of thing and picture, also can change easily different imaging things.It is even that the setting of light guide can guarantee to be irradiated to light on object, is conducive to improve image quality.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 2, thing screen 1 is provided with circular light hole 11, and thing shields 1 bottom and is linked with the vertical rod 12 for fixture screen 1.
As shown in Figure 3, object 2 is made up of as thing 21 and the collar first 22 that is fixed on imaging thing 21 peripheries round-formed, and imaging thing 21 is provided with the imaging article pattern of hollow, is also provided with azimuth bar 23 in collar first 22, is used to indicate the orientation of imaging thing 21.
As shown in Figure 4, light guide 3 is made up of circular light guide sheet 31 and the collar second 32 that is fixed on light guide sheet 31 peripheries.
Thing screen 1 is ferrous material, and collar first 22 and collar second 32 are magnetic material; Collar first 22 is identical with the diameter of collar second 32, is all greater than the diameter of light hole 11; Light guide sheet 31 is pmma material.
As shown in Figure 1, object 2 is adsorbed on the light hole 11 of thing screen 1 by collar first 22, and light guide 3 is adsorbed on object 2.
Imaging article pattern on object 2 is asymmetric, left-right asymmetry pattern up and down.Figure 5 shows that typical object imaging thing schematic diagram, in figure, a is asymmetric word, and b is asymmetric numeral, and c is asymmetric letter, and d and e are asymmetric figure.
