Description
Technical field
The utility model relates to Experiments of Optics apparatus field, particularly relates to a kind of physics imaging demonstration instrument.
Background technology
In optics, the picture being polymerized to by the actual light congruence, is called real image, can accept with optical screen; Otherwise, being called the virtual image, can only be felt by eyes.Experienced teacher of physics, in the time telling about the difference of real image and the virtual image, tends to mention so a kind of differentiating method: " real image all stands upside down, and the virtual image is all upright." what is called " upright " and " handstand ", yes for the original.
Three kinds of virtual images that level crossing, convex mirror and concavees lens become are all upright; And the real image that concave mirror becomes with convex lens, and the real image becoming in pinhole imaging system, all stand upside down without exception.Certainly, concave mirror also can become the virtual image with convex lens, and two kinds of virtual images that they become are upright state equally.
Above-mentioned is all the conclusion drawing through physical optics imaging experiment, just need in physics experiment teaching, make corresponding instrument and test in order to confirm these conclusions, therefore just there are various experiment equipments, what traditional lens imaging experiment was used is thermal light source candle, because can causing flame core in the process of lighting, candle moves down, in optical bench, need constantly to adjust the problem such as lens and optical screen height distance, view finding, ranging process trouble very, and use candle class nature naked light easily to occur experiment accident, bring unsafe factor to experimentation.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of physics imaging demonstration instrument that can solve above-mentioned prior art problem.
To achieve these goals, the technical solution adopted in the utility model is: a kind of physics imaging demonstration instrument, comprise luminophor, optical lens tabula rasa and projection plate, described luminophor, optical lens tabula rasa and projection plate are arranged on a carriage successively by support member respectively; Described support member is scalable, and carriage is provided with the sliding tray of " ⊥ " font, and support member snaps in sliding tray; Between described luminophor, optical lens tabula rasa and projection plate, be respectively equipped with telemeter rod, described telemeter rod is the rule that is fixed on carriage surface, and described rule is symmetric ruler; In the middle of described optical lens tabula rasa, be provided with slot, in described slot, be inserted with light penetrating device, described light penetrating device also comprises and luminophor and the projection plate shadow shield with through hole on same axis, and described luminophor, optical lens tabula rasa and projection plate are fixed on carriage by support member respectively.
Further, described luminophor is thermal light source or cold light source.
Further, described light penetrating device comprises convex lens, concavees lens or level crossing.
Compared with prior art, the beneficial effect of this utility model: convenient installation, mobile, and can not use naked light to serve as luminophor, avoid the Air-pollution From Combustion air of nature naked light and bring factor leading to social instability to experimentation, the measurement accurate distance numerical value of this New Energy safe ready in experiment, can complete the Physical Experiment of convex lens, concave mirror, level crossing or pinhole imaging system simultaneously.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Embodiment: referring to Fig. 1 to Fig. 5, a kind of physics imaging demonstration instrument, comprise luminophor 2, optical lens tabula rasa 3 and projection plate 4, described luminophor 2, optical lens tabula rasa 3 and projection plate 4 are arranged on a carriage 1 successively by support member 5 respectively, described support member 5 is scalable, carriage 1 is provided with the sliding tray 10 of " ⊥ " font, and support member 5 snaps in sliding tray 10, between described luminophor 2, optical lens tabula rasa 3 and projection plate 4, is respectively equipped with telemeter rod 6;
Further, in the middle of described optical lens tabula rasa 3, be provided with slot, in described slot, be inserted with light penetrating device 7.
Further, described luminophor 2 is thermal light source or cold light source.
Further, described light penetrating device 7 comprises convex lens, concavees lens or level crossing.
Further, described telemeter rod 6 is for being fixed on the rule on carriage 1 surface, and rule is centered by the position of optical lens tabula rasa 3, to the scale symmetry of two ends extension.
Further, described light penetrating device 7 also comprises and luminophor 2 and projection plate 4 shadow shield with through hole on same axis.
In experiment, should adopt safe light emitting source for luminophor 2, as produced, heat is little, LED lamp that light intensity is enough, as the 2 use miniature bulbs 2 of luminophor in Fig. 4～, wire, battery 8 and housing 9 be assembled into a light emitting source.Can select different light penetrating devices for imaging experiment classification simultaneously, convex lens are selected in convex lens imaging, pinhole imaging system is selected the shadow shield with through hole, in experimentation, the support member 5 of adjustable support luminophor 2, optical lens tabula rasa 3 and projection plate 4 carrys out thing three and reaches on unified imaging horizontal line, the effect of the relative distance capable of regulating imaging of mobile three on carriage 1 simultaneously, can draw triangular accurate distance numerical value according to the telemeter rod 6 on carriage 1 simultaneously.
This practical carriage 1 is provided with sliding tray 10 for length axes, in sliding tray 10, slide block is installed, and is fixed with height-adjustable support member 5 on slide block, fixes luminophor 2, optical lens tabula rasa 3 and projection plate 4 on support member 5.
Because optical lens tabula rasa 3 of the present utility model can not limit the function of lens, so experimenter can use various types of lens to complete experiment easily in slot; Meanwhile, arranging of slot can also be placed narrow meshed shadow shield and carried out the experiment of " pinhole imaging system ".
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain, all should belong to protection domain of the present utility model as long as what realize the utility model object with essentially identical means.
