Abstract
The utility model relates to a fan shaped demonstration device of laser ray, comprising a laser radiating case (1) which is applied to eradiate the laser and an optical lens (2) which can generate optical phenomenon. The optical lens (2) is arranged at the laser route of the laser radiating case (1) which is composed of laser of linear source. The laser of linear source of the utility model produces a linear light patch instead of a circular light patch to make the light patch clear. And the tabular optical lens can provides a much clearer view of the route of the light incidence, reflection and refraction and so on when the laser ray goes through the optical lens. The utility model can not only give a view of the route of light incidence, reflection and refraction in the optical lens which is vertical with the fan shaped light plane, but also can be applied to contrapose with the teaching diagram with the light route so as to supply a deep understanding and application of the optical formulas; the plurality of the laser simultaneously project in the optical lens fully provide a view of different light route in the identical optical lens.
Description
Technical field
The utility model relates to a kind of fan-shaped laser beam demonstration teaching aid.
Background technology
One of the general employing of former light demonstration teaching aid or one group of non-linear laser instrument are projected on the ball optic lens of different concavo-convex degree, phenomenons such as the incident of light, reflection, refraction are reflected on the cross section vertical with light, and what show in the cross section is the circle hot spot.
Its shortcoming is after laser is incident to ball optic lens, phenomenons such as reflection, refraction can only be reflected on the cross section vertical with light, the phenomenons such as incident, reflection, refraction of can not image, seeing light intuitively change at the light circuit, and what show on the cross section only is a roundlet hot spot, influences observing effect.
The utility model content
The utility model has solved the variation that can not show various optical phenomena light paths such as incident, reflection and refraction that exists in the above-mentioned existing optics demonstration teaching aid and only can show technical matterss such as difficult observation such as justifying hot spot on the cross section.
The technical solution of the utility model is: a kind of fan-shaped laser beam demonstration teaching aid is provided, this teaching aid comprises the laser radiation box 1 of launching laser rays and the optical lens 2 that can produce optical phenomena, described optical lens 2 is arranged on the laser optical path of laser radiation box 1, and its special character is: described laser radiation box 1 is made of the laser instrument of linear light source;
Above-mentioned optical lens 2 is a pancake.
The laser instrument of above-mentioned linear light source is one or more.
The laser instrument of above-mentioned linear light source becomes the equidistant arrangement of symmetry.
Above-mentioned optical lens 2 is made of the optical lens of one or more different geometries.
Be equipped with light barrier 3 between above-mentioned laser radiation box 1 and the optical lens 2.
Above-mentioned light barrier 3 is provided with one or more light holes.
Above-mentioned teaching aid also includes the optics teaching chart.
Be provided with adsorbent below above-mentioned laser radiation box 1, optical lens 2 or the light barrier 3.
Above-mentioned adsorbent is a magnetic stripe.
The utlity model has following advantage:
1, the utility model adopts the laser instrument of linear light source, makes that to be radiated on the cross section be not a round hot spot, but the straight line hot spot seems more clear.
2, because used flat optical lens, can clearer demonstration laser beam light path by various optical phenomenas such as optical lens incident, reflection or refractions.
3, not only can be on the plane vertical with the ray fans plane, see the routes such as incident, reflection, refraction of light in the optical lens, can also be with light path and instructional chart contrast, intensification is to the understanding and the utilization of optics formula.
4, organize laser incident simultaneously is presented at the different light paths in the optics lens, more comprehensively more.
Description of drawings
Fig. 1 is the structural representation of a kind of fan-shaped laser beam demonstration teaching aid of the utility model;
Fig. 2 is the structural representation of light barrier in a kind of fan-shaped laser beam demonstration teaching aid of the utility model.
Embodiment
Referring to Fig. 1, a kind of fan-shaped laser beam demonstration teaching aid of the utility model comprises laser radiation box 1 and pancake optical lens 2, and wherein laser radiation box 1 is by the laser constitution of one group of linear light source, and optical lens 2 is arranged on the laser optical path of laser radiation box 1.The laser instrument of linear light source becomes the equidistant arrangement of symmetry.The laser beam that linear light source laser instrument in the laser radiation box 1 is launched sees through optical lens 2 and produces optical phenomenas such as incident, reflection, refraction, can see the variation of light path in the optical phenomena processes such as incident, reflection, refraction.
Between laser radiation box 1 and optical lens 2, a light barrier 3 can be set, be used for arbitrarily covering some Shu Jiguang that laser radiation box 1 penetrates.In order to represent, measure optical path change, can increase by a cover optics teaching chart.
Wherein, laser radiation box 1 is by the laser constitution of one group of linear light source, and this group laser level is arranged, and the light emission direction of laser instrument is identical.Optical lens 2 can be the optical lens or the prism of various different geometries, in order to show different optical phenomenas, can select the optical lens of different geometries.On light barrier 3, be provided with several light holes.
For optics teaching aid of the present utility model is demonstrated, can below laser radiation box 1, optical lens 2, light barrier 3 or optics teaching chart, establish one deck adsorbent on the demonstration board of erectting.If the demonstration board of erectting is the irony clipboard, then adsorbent can be a magnet.
In order to be clear that the light of optical lens 2 inside, can below optical lens 2, establish the small pieces of cloth used for patches thing, the simplest way is to paste one deck blank sheet of paper, and light is also had a panoramic view in the light path of optical lens 2 inside.
During use, at first laser radiation box 1, optical lens 2, optics teaching chart are adsorbed on the irony clipboard of setting or lie on table (platform) face.Then, press the switch on the laser radiation box 1, energized.Make each laser instrument in the laser radiation box launch upper and lower to each other flushing, between left and right every equating and band look fan-shaped laser beam parallel to each other to same direction.The light path of this light beam at first displays on the optics teaching chart below the laser radiation box 1 that is setting off, reenter on the optical lens 2 that is incident upon laser radiation 1 front, light is at different densities, optical phenomenas such as the incident on the difform material interface, reflection, refraction all on the lining paper below optics teaching chart and optical lens 2 with band coloured light line lines with the light path image, be presented in face of the spectators intuitively.In when demonstration, can as required light barrier 3 be placed on laser radiation box 1 before, block a branch of or a few Shu Jiguang, because the light hole on the light barrier 3 adopts non-equidistant design can make laser beam the combination of diverse location occur.Adopt difform optical lens 2 can demonstrate multiple optical principle with different optics teaching charts.
