A laser tube and the light source regulator are arranged on the light source bracket, the incidence mirror and the reflecting mirror are respectively installed on the mirror bracket, the incidence mirror is positioned between the light source and the reflecting mirror, and the position on the incidence mirror, that corresponds to an emission hole of the laser source, is provided with a through incidence hole. The micro deformation amplifier has the advantages of good collimation and directivity of laser beams, high light intensity, easy adjustment, small size, light weight and low cost, and can easily gain faculae that has larger magnification and higher luminous intensity after multiple reflections between two plane mirrors.
Description
It is the teaching aid of feature to adopt optical means that the utility model relates to a kind of.
When producing miniature deformation at physics lesson demonstration object receiving force, existent method is by teacher's self-leveling line light source, level crossing, forms device as shown in Figure 1, does not have ready-made experimental apparatus or teaching aid.The main deficiency of above-mentioned experiment is 1) light source is undesirable, and the beam collimation that general light source sends is poor, not parallel, is difficult for repeatedly reflecting; 2) owing to repeatedly do not reflect, so hot spot mobile not obvious on the wall, experiment effect is not obvious; 3), therefore be difficult for adjusting the inconvenience demonstration because incident light must be injected two spaces between the level crossing from the side.
The purpose of this utility model is to provide a kind of hot spot to move obviously, and experiment effect is obvious, adjusts the miniature deformation amplifier easy with demonstration, produces the physical phenomenon of miniature deformation with the demonstration object receiving force.
The utility model is made up of LASER Light Source, incident mirror, catoptron, light source bracket and light source adjuster, mirror support.LASER Light Source is arranged on the light source bracket, the light source adjuster is located on the light source bracket, so that adjust the locus of light source, incident mirror and catoptron are installed on the mirror support respectively, the incident mirror is between LASER Light Source and catoptron, light source bracket is connected with the incident mirror support, and the perforation of going into of perforation is offered in the position of corresponding LASER Light Source perforation hole on the incident mirror, so that laser beam is incident upon on the catoptron from going into perforation.
LASER Light Source can adopt laser diode (being commonly called as laser pen) commonly used in toy.The light source adjuster can adopt band to adjust the screw rod of knob.
Because laser beam monochromaticity is good, collimation and high directivity, brightness height, laser beam can directly be mapped on the catoptron by going into perforation behind the incident mirror, through the repeatedly reflection of two level crossings, be mapped to again on the wall at a distance, therefore can obtain experimental demonstration effect preferably.During experiment, when producing miniature deformation under the effect of demonstration desktop in power, incident mirror and catoptron and the laser tube that is fixed on the incident mirror support all turn over a certain angle θ downwards, according to reflection law, every through primary event, catoptrical direction is all than the multidirectional deflect of original direction 2 θ angles.Light beam is through repeatedly reflecting, amplifying, and when shining on the far ultraviolet wall again, its hot spot moves up and down fairly obvious, thereby the miniature deformation that desktop is produced under the effect of power is described at an easy rate.
Obviously the utlity model has following advantage: 1) laser beam datum is strong, the light intensity height, and good directionality is easy to still have bigger light intensity after repeatedly reflecting between two level crossings, observes easily, and this is that general light source is unapproachable.2) LASER Light Source is selected laser diode for use, is commonly called as laser pen, is fixed together with support or optical bench easily, needn't establish source of parallel light in addition, and volume is little, in light weight, price is low, easily self-control or production in enormous quantities.3) because laser tube and support are fixed together, and therefore when desk deformation deflection θ angle, laser tube and support also turn over the θ angle simultaneously, promptly light source itself also participates in amplifying, and magnification is just bigger.4) laser beam is injected from going into perforation, and incidence point is located at incident mirror minute surface middle part, is easy to adjust parallel, and makes it repeatedly reflect, as long as each minute surface has 3～4 secondary reflections, this experimental result is just very satisfied.
Fig. 2 is a structural drawing of the present utility model.
From Fig. 2 as seen, the utility model is made up of laser diode (laser pen) 1, incident mirror 2, catoptron 3, light source bracket 4, light source adjuster 5, incident mirror support 6 and mirror support 7.Laser diode 1 is fixing by light source bracket 41,42, and light source adjuster 5 is selected for use and adjusted screw rod 51 and adjust knob 52, adjusts surface level one end that screw rod screws in light source bracket 42.Arc light source bracket 41 with the laser diode buckle between light source bracket 42 and 41, light source bracket 42 is fixed together with incident mirror support 6, incident mirror 2 and catoptron 3 are vertically fixed on respectively on incident mirror support 6 and the mirror support 7, and that offers perforation in the position that incident mirror 2 penetrates hole 11 with respect to laser diode light source goes into perforation 21.The about 30cm of distance between incident mirror and the catoptron.Mirror support also can be designed to whole optical bench.
