Background technology
At present, being used for the Experiments of Optics device of physics geometrical optics content, mainly is to use a kind of optical disk, demonstrates according to different structural group is incompatible.The shortcoming of this optics teaching aid is: can not clearly show advancing and change procedure of light in the experiment, comprise focus variations, change of reflection, change in refraction etc., the weak effect of demonstrating directly perceived in teaching; A kind of optics teaching aid that adopts Gas LASER Tube to do light source is also arranged, though can show light path, its starting voltage is the 5-6 kilovolt, and operating voltage is 1 kilovolt, need show light path with smoke-box or darkroom, make complicated, use dangerous, the production cost height, use dumbly, inconvenience is difficult to promote.
Summary of the invention
It is strong that technical problem to be solved in the utility model provides a kind of sense directly perceived, just but clear view arrives light course and situation of change thereof in bright chamber, and operating voltage is low, simple in structure, make easily, usage charges are low, the multi-functional light path display optical teaching aid of flexible and convenient operation.
For solving above technical matters, the technical scheme that the utility model adopted is: this multi-functional light path display optical teaching aid, by fixed mount, circular carrier, light-beam transmitter constitutes, light-beam transmitter is stuck on the edge of circular carrier, and can slide along the edge of circular carrier, on a semi circular surface on the circular carrier front face, paste first circular optically denser medium plate, paste first circular focussing glass on another semi circular surface, and semicircle optically denser medium plate and semicircle focussing glass are bonding circular, its radius is less than the radius of circular carrier, being beneficial to light-beam transmitter slides along circular carrier edge, be provided with the optically denser medium platform that optical mirror is placed at the interface place of semicircle optically denser medium plate and semicircle focussing glass, the width of the optically denser medium platform that optical mirror is placed is advisable can put optical mirror.The utility model is also implemented by following measure: described semicircle optically denser medium plate is the polymer based nanocomposites transparent body (comprising translucent body), can be by acrylate, nano powder (as gas-phase silica), one-tenth such as coupling agent are grouped into, after earlier nano powder being carried out modification with coupling agent, mix with acrylate again, after fully disperseing (as ultrasonic dispersing), form the colloidal dispersion system of solid-liquid two-phase, through photocuring or thermal polymerization, make transparent or semitransparent polymer-based nano complex, on the periphery of semicircle optically denser medium plate and semicircle focussing glass, be provided with the rotational angle indicating graduation, but Direct observation light refraction, reflection, the angle of incident, on the optically denser medium platform that optical mirror is placed, place optical mirror, it on optical mirror optically thinner medium (as air), the optically thinner medium back is the hair side of semicircle focussing glass, the course of the hair side by focussing glass when clearly display light is by optically thinner medium; Described light-beam transmitter is made of installation tube, geometrical clamp, in being installed, tube is provided with switch, battery, laser semiconductor, lens from top to bottom successively, tube is installed to be fixed by bolts on the riser of geometrical clamp, and tube is installed can rotate around the axis of bolt, turn to and tighten bolt when needing the position, light-beam transmitter is clamped on the edge of circular carrier with geometrical clamp, light-beam transmitter can be established 1-4 according to the demonstration needs, and the axis parallel that tube is installed is in the plane of semicircle optically denser medium plate and the plane of semicircle focussing glass; Described circular carrier is transparent plectane, so that the teacher also can see the demonstration of light in the back; Circular carrier is fixed on the rotation axis, rotation axis by Bearing Installation in fixed mount, be provided with the rotation axis hold-down nut in the rotation axis outer end, rotation by rotation axis, can realize the orientation adjustment of semicircle optically denser medium plate and semicircle focussing glass, when reaching the demonstration orientation that needs, available rotation axis hold-down nut is fixed; The optically denser medium platform that described optical mirror is placed is the platform of semicircle optically denser medium plate and the semicircle focussing glass thickness difference formation when bonding.When using the utility model, one or several light-beam transmitter is clipped in simultaneously on the edge of circular carrier, turns on the power switch, adjust light beam and can carry out the demonstration of respective optical character.When for example demonstrating the refraction of light and reflex, can on the optically denser medium platform that optical mirror is placed, place a coated glass bar, light-beam transmitter is clipped in the top, turn on the power switch, adjust light beam, making light beam pass optically thinner medium (as air) shines on the coated glass bar, on the hair side of semicircle focussing glass, can show incident ray and reflected ray, in semicircle optically denser medium plate, can demonstrate refracted ray, sliding fixation clamp, adjustment incident angle size demonstrates the respective change at reflection angle and refraction angle on the display board, thereby clearly, dynamically complete demonstration light enter the reflection that optically denser medium takes place from optically thinner medium, the change in refraction phenomenon; If during the experiment of demonstration convex lens focus, on the optically denser medium plate platform that optical mirror is placed, put a semicircle single protruding glass block, and on circular carrier, establish three light-beam transmitters simultaneously, a middle light-beam transmitter passes the center of circular single protruding glass block as primary optical axis, adjust the light-beam transmitter of both sides, make its parallel protruding glass block of circular list that passes with primary optical axis, on the hair side of semicircle focussing glass, can see three parallel incident rays, can see three light beams that intersect at any in semicircle optically denser medium plate, the point of crossing is focus; Require the position as if other optical mirror is placed on, suitably dispose light source, can finish the demonstration of respective optical.
The beneficial effects of the utility model are: this multi-functional light path display optical teaching aid, can be clear the advancing and situation of change of light in the display optical experiment, but the change procedure of dynamic demonstration light can be finished whole experiment contents of geometrical optics; Owing to adopted polymer based nanocomposites and frosted glass background, the effect of demonstration is more directly perceived, in bright chamber clearly display effect can be arranged, and need not carry out in smoke-box or darkroom; This multi-functional light path display optical teaching aid also has the characteristics of flexible and convenient operation, and the user expands space the formula of the probing into teaching and study that are adapted to the promotion of the current Ministry of Education of the state especially and carry out if having more greatly; The light source of this multi-functional light path display optical teaching aid adopts semiconductor laser light resource, and required voltage is low, and is safe in utilization; Integral manufacturing is simple, and cost and usage charges are all lower, are beneficial to popularization.
