The technical features of the color rainbow principle demonstrating apparatus are that the color rainbow principle demonstrating apparatus comprises an iron stand and support, a thin-wall glass test tube, a cylindrical white paper optical screen, a laser pen module, and a laser pen clamp, that cylindrical white paper optical screen is installed on the horizontal surface of the iron stand and support, that a slit is disposed on a side of the cylindrical white paper optical screen, that the thin-wall glass test tube is installed in the cylindrical white paper optical screen coaxially and fixed on the iron stand and support, that the laser pen module is installed on the laser pen clamp, that the laser pen clamp is arranged on the outer side of the iron stand and support, and that light beams emitted from the laser pen module are irradiated to thin-wall glass test tube inside the cylindrical white paper optical screen via the slit on the cylindrical white paper optical screen and are refracted multiple times to form images on the cylindrical white paper optical screen. The color rainbow principle demonstrating apparatus is reasonable in design and capable of really simulating the principle of a rainbow and increasing teaching efficiency, and has characteristics of simple structure, realistic form, and easy and convenient use.
Description
Technical field
The utility model belongs to optics teaching Instrument technology field, especially a kind of colour rainbow presentation device of theory.
Background technology
In optics teaching process, in order to show intuitively rainbow phenomena, conventionally adopt Rainbow Demonstration Installment to realize the demonstration of rainbow phenomena.Existing Rainbow Demonstration Installment only can be simulated monochromatic light (red laser) and is radiated at and on water droplet, produce multiple refraction and form rainbow, but U.S.A of rainbow is that it is bright in luster, the analog demenstration producing by one-wavelength laser is not only uninteresting, and cannot simulate the difference of light shooting angle (angle of minimum deviation) after multiple refraction of different wave length.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of colour rainbow presentation device of theory of reasonable in design, lifelike image is provided.
The utility model solves existing technical matters and takes following technical scheme to realize:
A kind of colour rainbow presentation device of theory, comprise iron stand and support, thin-walled glass test tube, cylindric blank sheet of paper optical screen, laser pen module and laser pen fixture, cylindric blank sheet of paper optical screen is arranged on the surface level of iron stand and support, in cylindric blank sheet of paper optical screen one side, be shaped with a slit, thin-walled glass test tube is coaxially arranged in cylindric blank sheet of paper optical screen and is fixed on iron stand and support, laser pen module is arranged on laser pen fixture, this laser pen fixture is positioned at the outside of iron stand and support, the emitted light beam of this laser pen module is by the thin-walled glass test tube in the cylindric blank sheet of paper optical screen of the slit directive on cylindric blank sheet of paper optical screen and imaging on cylindric blank sheet of paper optical screen after multiple refraction.
And described laser pen module comprises arranges red laser pen, green laser pen and violet laser pen from top to bottom.
And the power of described red laser pen is 200mw, the power of described green laser pen is 150mw, and the power of described violet laser pen is 500mw.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, the thin-walled glass test tube that it is fixedly filled with water with iron stand and fixture and cylindric blank sheet of paper optical screen, with the laser pen of the fixing different colours of laser pen fixture and make to inject thin-walled glass test tube in the slit of laser pen light beam from optical screen, just can on optical screen, observe different colours, the projection of the light of different wave length after by multiple refraction, and can contrast mutual position and calculate the angle of minimum deviation of the light of different wave length, really simulated the principle of rainbow, improved efficiency of teaching, have simple in structure, lifelike image, the feature such as easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
A kind of colour rainbow presentation device of theory, as shown in Figure 1, comprise iron stand and support 1, thin-walled glass test tube 2, cylindric blank sheet of paper optical screen 3, laser pen module 5 and laser pen fixture 6, cylindric blank sheet of paper optical screen is arranged on the surface level of iron stand and support, in cylindric blank sheet of paper optical screen one side, is shaped with a slit 4, thin-walled glass test tube is coaxially arranged in cylindric blank sheet of paper optical screen and is fixed on iron stand and support, laser pen module comprises red laser pen, green laser pen and violet laser pen, red laser pen, green laser pen and violet laser pen are arranged on laser pen fixture from top to bottom successively, this laser pen fixture is positioned at the slit on the outside of iron stand and support and the emitted cylindric blank sheet of paper optical screen of beam-pointing of laser pen module, laser pen module is irradiated on the thin-walled glass test tube in cylindric blank sheet of paper optical screen by this slit, can imaging on optical screen after multiple refraction.
In the present embodiment, laser pen on laser pen fixture is respectively the violet laser pen that red laser pen that power is 200mw, green laser pen that power is 150mw and power are 500mw, due to the laser pen brightness difference of different colours, in addition the sensitivity difference of human eye to different wave length light, therefore the power of above laser pen is best.The thin-walled glass test tube of filled with water is for simulating the drop of steam, this test tube wall <1mm, test tube diameter >10mm.Utilize the length of thin-walled glass test tube, can three beams of laser be radiated to slightly biased position, center from top to bottom simultaneously, play how double refracting effect.Laser pen module is irradiated to being filled with water on thin-walled glass test tube in cylindric blank sheet of paper optical screen by the slit on cylindric blank sheet of paper optical screen, can imaging on optical screen after multiple refraction, now can be observed the hot spot of three kinds of colors, and poor arrangement at an angle.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model comprises and is not limited to the embodiment described in embodiment; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
