Abstract
The utility model discloses an optical reflection demonstrator used for teaching. The optical reflection demonstrator used for teaching includes a box body. At least one reflector is arranged in the box body. The box body is provided with a light beam emitting device. A light beam outlet of the light beam emitting device is directed into the box body. The box body is provided with a light beam track projection screen. The light beam emitting device emits light beams and the light beams enter into the box body and are reflected by the reflector. Since the box body is enclosed and filled with darkness, the reflector and a motion track of the light beams are projected on the light beam track projection screen and are disposed in a highlight form. The optical reflection demonstrator used for teaching provided by the utility model is suitable for demonstrating optical reflection experiments, and is convenient for observing results, convenient to use, accurate in experiment results and insusceptible to influence of experimental instruments.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of teaching aid of optical reflection demonstration.
Background technology
The optical reflection experiment is important on a physics lesson experiment, but experimental result often is subjected to many-sided influences such as environment, light, teaching aid, clearly lecture experiment makes the student can not grasp knowledge well like this, and can't motivate students' interest in learning.
The utility model content
Technical problem to be solved in the utility model provides a kind of demonstration that is applicable to the optical reflection experiment, is convenient to observations, and easy to use, experimental result is accurate, is not subjected to the teaching optical reflection demonstration device of environmental experiment utensil.
For solving the problems of the technologies described above, the technical solution of the utility model is: teaching optical reflection demonstration device, comprise casing, be provided with at least one catoptron in the described casing, described casing is provided with beam launcher, the beam outlet of described beam launcher is pointed in the described casing, and described casing is provided with the beam trajectory projection screen.
As optimized technical scheme, described beam trajectory projection screen is provided with the coordinate gridline.
As to improvement of the technical scheme, described beam trajectory projection screen is fluorescent display screen.
As to further improvement in the technical proposal, described casing is provided with the mirror angle adjusting knob that is connected with described catoptron.
As the further improvement to technique scheme, described casing is provided with the beam angle adjusting knob that is connected with described beam launcher.
As the especially further improvement to technique scheme, described casing is provided with the brightness contrast adjusting knob of beam trajectory projection screen.
Owing to adopted technique scheme, teaching optical reflection demonstration device, comprise casing, be provided with at least one catoptron in the described casing, described casing is provided with beam launcher, the beam outlet of described beam launcher is pointed in the described casing, and described casing is provided with the beam trajectory projection screen; Described beam launcher emission light beam, light beam injects in the described casing, gets to reflection then on the described catoptron, because dark for sealing in the described casing, the movement locus of described catoptron and light beam is incident upon on the described beam trajectory projection screen, shows with highlighted form; The utility model is applicable to the demonstration of optical reflection experiment, is convenient to observations, and easy to use, experimental result is accurate, is not subjected to the influence of environmental experiment utensil.
