Background technology
The experimental apparatus of middle school student's physical optics education experiment use at present only has " anti-, the refraction demonstration device of light " and " optical disk " that is numbered J2501 that are numbered the J2528 type, and they all use white light as light source, and experiment effect is not good; Have behind the laser beam expanding as light source, the incident point or the incident line on back screen behind the laser beam expanding is used as light itself, made scientific mistake.
Chinese patent ZL200620144617.1 provides a kind of mist, liquid formula optics comprehensive test instrument, comprise tool housing, built-in convex lens, concavees lens, diffuse reflection metal forming tortoise, semicircle glass block, level crossing, cooperate laser pen, the smog of sealing, mixed liquor utilizes smog, mixed liquor produces bright stable light path to the scattering of laser and finishes light in the physical optics teaching material of middle school along rectilinear propagation, the reflection of light rule, water is to the refraction of light, glass is to the refraction and the law of refraction of light, the diffuse reflection of light and direct reflection, the total reflection of light and critical angle are measured, the light vertical incidence water surface or glass, the converging action of convex lens, Experiments of Optics such as the disperse function of concavees lens.
Chinese patent ZL200820008367.8 provides a kind of mist, liquid formula middle school Optical-Physics Experiment instrument, comprises mist, liquid formula optics comprehensive test instrument 1, scalable base 2, optical screen 3, scalable fork 4, two parallel laser light source 5, fills cigarette hole 6, vernier adjustment knob 7, magnetic 8, optical fiber model 9, diffraction plate support 10, web member 11, convex mirror 12, concave mirror 13.Can finish light in the physical optics teaching material of middle school along rectilinear propagation, the reflection of light rule, water is to the refraction of light, glass is to the refraction and the refraction law of light, the diffuse reflection of light, the direct reflection of light, the total reflection of light and critical angle are measured, the light vertical incidence water surface, light vertical incidence glass, the converging action of convex lens, the disperse function of concavees lens, the converging action of concave mirror, the disperse function of convex mirror, optical fiber communication---light conduction analog, interference of light, Experiments of Optics such as diffraction of light.
Above-mentioned binomial patented technology can both be finished many Experiments of Optics and can truly reflect the travel path of light, but because their device pattern is single, and mostly optical element be to fix, and lacks dirigibility, is not suitable for the student and does combination experiment.
Summary of the invention
In order to solve the problem that spray film formula optical instrument pattern in the prior art is single, lack dirigibility, the utility model provides a kind of spray film formula geometrical optics experiment instrument, this experiment instrument can not only be finished a plurality of Experiments of Optics, and can satisfy the teacher and select the optics experiment equipment to impart knowledge to students targetedly flexibly according to teaching material.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of spray film formula geometrical optics experiment instrument, comprise optical element and Experiments of Optics box, the three-dimensional closed container of described Experiments of Optics box for constituting by base plate, top board, header board, back plate and side plate, described optical element is placed in the Experiments of Optics box, described Experiments of Optics box is rectangular parallelepiped on the whole, experiment box left plate is provided with and fills the cigarette hole, and experiment box top board is provided with exhaust smoke hole; Described optical element comprises white light source, prism and optical screen, white light source is located at experiment box right side, optical screen is located at experiment box left side, and prism is attached on the magnetic that is positioned at plate inboard behind the experiment box, and the plate outside is provided with the magnet that cooperates with above-mentioned magnetic behind the experiment box.
