Abstract
The utility model relates to an experiment apparatus, and especially relates to a light source device used for convex lens imaging, comprising an experiment rack. The light source device is characterized in that: the experiment rack is successively provided with an electric torch which is fixed by a paper sleeve, a convex lens, and a development plate; wherein a light source position of the paper sleeve is provided with a light shading plate with a light hole. Therefore, the light source device used for convex lens imaging provided by the utility model has the beneficial effects of simple structure, fixed light source, high definition, small error, convenience and practicability.
Description
(1) technical field
The utility model relates to a kind of experiment equipment, particularly a kind of convex lens imaging light supply apparatus.
(2) background technology
In textbook, the light supply apparatus that the convex lens imaging of generally mentioning is used is candle, because candle flame self has certain thickness along the lens major axes orientation, this brings difficulty can for the position of determining picture, thereby makes that the measurement data error is bigger; Candle constantly shortens in the process of burning, just must readjust the height of candle after a period of time of therefore burning when optical screen can not find the position of picture; The candle flame easily rocks and the size instability, thereby the sharpness of picture exerts an influence and the inconvenience observation on the aiming screen; Candle is difficult for fixing in experimentation, if also cause fire accidentally easily, has potential safety hazard.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provides that a kind of light source is fixed, sharpness height, convex lens imaging light supply apparatus that error is little.
The utility model is achieved by the following technical solution:
A kind of convex lens imaging light supply apparatus comprises experiment frame, it is characterized in that: install fixing electric torch, convex lens and the video boards of band paper web on the described experiment frame successively, described paper web light source place is provided with the shadow shield of band light hole.
Therefore, the beneficial effects of the utility model are: this convex lens imaging light supply apparatus, simple in structure, light source is fixed, sharpness height, error are little, convenient and practical.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.Among the figure, 1 paper web, 2 electric torchs, 3 shadow shields, 4 convex lens, 5 video boards.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises experiment frame, it is characterized in that: install electric torch 2, convex lens 4 and video boards 5 that band paper web 1 is fixed on the described experiment frame successively, described paper web 1 light source place is provided with the shadow shield 3 of band light hole.
Adopt convex lens imaging light supply apparatus of the present utility model, when doing experiment, can will open with paper web 1 fixing electric torch 2, paper web 1 is to be used for fixing electric torch 2, make the light source of electric torch 2 avoid diffusion and energy parallel rays, after light source appears, pass through convex lens 4 video picture on video boards 5 by the light hole on the shadow shield 3, shadow shield 3 can arbitrarily be made the light hole shape, as asymmetric pattern, letters etc. can be observed intuitively from imaging on the video boards 5, as about also stand upside down, in the process of experiment, just can correct that the student is the sort of to be familiar with unilaterally like this, the wrong viewpoint of handstand up and down just when namely convex lens become real image; Use if just can be used as a source of parallel light after shadow shield 3 taken off, can be used for measuring the focal length of institute's use convex lens in the student experimenting etc.; Also solved the problems of teaching material Central Plains experiment,, light source fixed as flashing too " thick ", certain environmental pollution etc. arranged.Therefore, the beneficial effects of the utility model are: this convex lens imaging light supply apparatus, simple in structure, light source is fixed, sharpness height, error are little, convenient and practical.
Claims (1)
1. convex lens imaging light supply apparatus, comprise experiment frame, it is characterized in that: install band paper web (1) fixing electric torch (2), convex lens (4) and video boards (5) on the described experiment frame successively, described paper web (1) light source place is provided with the shadow shield (3) of band light hole.
