Description
technical field
The utility model relates to instruments used for education, particularly relates to the experimental apparatus for the teaching of Middle School Physics geometrical optics.
background technology
At present, the experimental apparatus that Middle School Physics geometrical optics education experiment uses, only there is " the reflection of light refraction demonstrator " and " the propagation experimentation instrument of light " that be numbered J2528 type, but their method is all to project incident point or the incident line on rear screen after laser beam is expanded, be used as " light " own, they are to draw " light path " with " light " bundle, and this is the same with draw light path on blackboard with chalk in essence, not being the path of light itself, is scientific mistake.Though have " mist, liquid formula optical synthetic experiment instrument (ZL200620144617.1) " and " mist, liquid formula secondary school physical optical experiment instrument (ZL200820008367.8)." they can complete many Experiments of Optics and can truly reflect the travel path of light; but its a lot of optical element symbol is all drawn on outer casing frontispiece; this has affected the observation while carrying out different experiments; caused unnecessary interfering with each other; simultaneously because light source is arranged on shell outside; light beam during to shell internal radiation part light caused damage by SKIN RETURN and refraction, affected the brightness of light path, the cigarette dirt on outer casing inner wall is also difficult to remove simultaneously.
summary of the invention
The utility model will provide a kind of built-in geometrical optics experiment instrument exactly, it can truly reflect the travel path of light, can complete many geometrical optics experiments, and can avoid different optical element and optical element symbol that the observation of done target experiment is produced and disturbed, can reduce loss and the raising light path brightness of light beam in communication process simultaneously, also more convenient to the cleaning of crock on shell.
The technical scheme that the utility model addresses the above problem is as follows: design a kind of built-in geometrical optics comprehensive test instrument, comprise base, transparent housing, activity context board package, little electric fan, handwheel, rocking arm, power supply, slot, light source bracket, fill cigarette hole, optical element, LASER Light Source, switch.It is characterized in that: base inside is provided with power supply, the front panel of base is provided with switch and handwheel, base upper panel is provided with light source bracket, slot, little electric fan, transparent housing is mobilizable, can be directly installed in the upper panel of base, the top of transparent housing is circular arc type, and another four sides are plane, and lower ending opening is also connected with base upper panel, slot is vertically set on the two ends of base upper panel, and activity context board package is inserted on the groove of slot and is vertical with base upper panel, activity context board package is provided with various optical elements, the activity context board package that each Experiments of Optics adapted is different, on activity context board package, be printed on the design symbol to testing, light source bracket is located at base upper panel central authorities, position is after activity context board package, light source bracket is provided with rocking arm, can rotate around the axis, the end of rocking arm is provided with semiconductor laser light resource, the rear plate of transparent housing is provided with one and fills cigarette hole, when after transparent housing cover upper bed-plate upper panel, light source bracket, LASER Light Source and rocking arm, activity context board package and optical element, little electric fan is all built among transparent housing.
The beneficial effects of the utility model are: the utility model is by above technical scheme, when making this built-in geometrical optics comprehensive test instrument complete great many of experiments, the loss of light still less, light path is brighter, crock on cleaning transparent housing is more convenient, can avoid different optical element and optical element symbol that the observation of done target experiment is produced and disturbed.The experiment that this built-in geometrical optics comprehensive test instrument can complete has: 1, light is tested along rectilinear propagation.2, reflection of light Rule.3, refraction and the refraction law experiment of glass to light.4, the converging action of convex lens experiment.5, the disperse function of concavees lens experiment.6, the mirror-reflection of light experiment.7, the diffuse reflection of light experiment.8, the total reflection of light and critical angle determination experiment.9, light vertical incidence water surface experiment.10, light vertical incidence glass surface experiment.11, the refraction experiment of water to light.12, the converging action of concave mirror experiment.13, the disperse function of convex mirror experiment.14, the smooth conduction analog experiment of optical fiber communication one.15, the refraction experiment of prism to light.16 convex lens and concavees lens combination experiment.17, light is slanted through water and light slants the comparative experiments to air from water from air.
