Abstract
The utility model discloses a demonstration instrument for geometrical optics. The demonstration instrument consists of a light source, a rack body, a graduated disk, a loading bracket, a lens bracket and a track, wherein the light source consists of three laser pens and a cylindrical lens located at the front ends of the three laser pens, and a graduated scale is arranged on the horseshoe-shaped graduated disk. After the laser pens emit laser light, the laser light is scattered into a concentric light beam through the cylindrical lens, a bright straight line instead of a point is formed when the laser light irradiates a plane, the bright straight line is formed in a manner that a demonstration light source irradiates the horseshoe-shaped graduated disk in a very small angle, and refraction and reflection experiments are carried out by using the propagation of the demonstration light line.
Description
Technical field
The utility model relates to a kind of instruments used for education, relates in particular to a kind of demonstration instrument of demonstrating geometrical optics.
Background technology
At present, when Optical-Physics Experiment is done in the laboratory by school, all be to utilize track to accomplish the measurement of focal length, can't see the propagation of light, the position measurement focal length through sharply defined image, intuitive and convenient not on the one hand, on the other hand, demo function is few.
Summary of the invention
The purpose of the utility model provides a kind of demonstrating visual, the geometrical optics demonstrator that demo function is various.
The purpose of the utility model realizes through following technical scheme; This geometrical optics demonstrator is by light source, support body, index dial, loading support, lens carrier, track; Said light source is made up of three groups of laser pens and the cylindrical lens that is positioned at three groups of laser pen front ends, and said laser pen is a semiconductor laser diode, and said index dial is connected with track through support body; Said index dial is the shape of a hoof; Said water chestnut form index dial is provided with rule, and said loading is propped up and is erected on the index dial, and said lens carrier is located on the track.
Behind laser pen emission laser, the process cylindrical lens will be scattered and be concentric beam, and irradiation no longer is a point in the plane, and becomes a bright straight line.To demonstrate light source and be radiated at low-angle very and form bright straight line on the water chestnut form index dial, utilize the propagation of this line demonstration light, reflect the reflection experiment.
The beneficial effect of the utility model: utilize the straight line be radiated on the index dial to serve as light, the propagation of seeing light that can be directly perceived, vivid, the convergence of the reflection of light, ray refraction, light and disperse or the like the optical phenomena in the geometrical optics.

Embodiment
As shown in Figure 1, this geometrical optics demonstrator is by light source 1, support body 8, index dial 2, loading support 3, lens carrier 4, track 5, and light source 1 is made up of three groups of laser pens 6 and the cylindrical lens 7 that is positioned at three groups of laser pen 6 front ends; Laser pen 6 is a semiconductor laser diode; Index dial 2 is connected with track 5 through support body 8, and index dial 2 is the shape of a hoof, and water chestnut form index dial 2 is provided with rule 9; Loading support 3 is located on the index dial 2, and lens carrier 4 is located on the track 5.
Behind laser pen 6 emission laser, process cylindrical lens 7 will be scattered and be concentric beam, and irradiation no longer is a point in the plane, and becomes a bright straight line.To demonstrate light source and be radiated at low-angle very and form bright straight line on the water chestnut form index dial 2, utilize the propagation of this line demonstration light, reflect the reflection experiment.
Reflection of light demonstration: as shown in Figure 4; Plane mirror is placed on the loading support 3; Open a laser pen, on water chestnut form index dial 2, can see a bright straight line, this straight line is radiated at catoptron and is reflected; Follow reflection law, can read the angle of incident ray and emergent ray through index dial 2.Thereby checking reflection law.
The refraction demonstration of light: as shown in Figure 5; Thick parallel flat is placed on the support,, container is placed on the loading support 3 if liquid is then contained in the container; Open a laser pen 6; On water chestnut form index dial 2, can see a bright straight line, this straight line is radiated on the interface can launch refraction effect, follows refraction law.The angle that can read incident ray through index dial 2, thereby checking reflection law.
The lens demonstration: as shown in Figure 6, adjustment demonstration light source 1 makes its emission rayed on water chestnut form index dial 2, be horizontal linear; Open three laser pens simultaneously, form a parallel ray beam, on the lift lens carrier, putting different lens (can be convex lens; Also can be concavees lens), after three straight lines are run into lens, will change its vergence; Consistent with light, can take place to assemble or disperse, can on water chestnut form index dial 2, see and assemble clearly or disperse straight line.
