The both sides of transparent liquid storage bottle first 4 are respectively equipped with circular arc slideway A(2) and circular arc slideway B(5), circular arc slideway A(2) and circular arc slideway B(5) place the center of circle overlap, circular arc slideway A(2) slide be provided with light source A(3), circular arc slideway B(5) slide be provided with light source B(6), light source B(6) light that sends is all the time perpendicular to the arcwall face of transparent liquid storage bottle first 4; Light source A(3), light source B(6) be laser generator, light source A(3) be red-light source, light source B(6) be green-light source, light source A is different with the light color that light source B sends, and is convenient to experiment and observes.
Refractometer assembly second comprises linear ramp C(10) and transparent liquid storage bottle second 14, the upper surface of transparent liquid storage bottle second 14 is provided with bottleneck second 141, the upper surface of transparent liquid storage bottle second 14 and linear ramp C(10) parallel, linear ramp C(10) slide be provided with can along any direction rotate light source C(11), light source C(11) be laser generator, the interior horizontal direction of transparent liquid storage bottle second 14 is provided with cuboid glass block 12 and semicylinder glass block 13; Each end face of cuboid glass block 12 is shiny surface, semicylinder glass block 13 and Graphic Panel B(9) parallel cross section is shiny surface, upper surface and the arcwall face of semicylinder glass block 13 are frosting; The upper surface of the upper surface of cuboid glass block 12 and semicylinder glass block 13 all with linear ramp C(11) parallel;
Described refractometer assembly third comprises the light source D(15 that horizontal direction sets gradually), De-dispersion prism group 16 and hot spot receiving screen 17; De-dispersion prism group 16 adopts the De-dispersion prism group in Abbe refractometer, light source D(15) be common high light light source, hot spot receiving screen 17 is white frosted plate, hot spot receiving screen 17 is vertically fixed on Graphic Panel B(9) on.
Can in the specific solvent such as poly-vinyl alcohol solution, liquor argenti nitratis ophthalmicus, there is typical laser light scattering phenomenon in laser, can clearly show the light vestige of laser, the utility model utilizes this character, the refraction effect occurring can demonstrate laser by interface in this colourless transparent solution time, phenomenon truth and clear, more simple and clear than setting-out on blackboard.
When use, first in transparent liquid storage bottle first 4 and transparent liquid storage bottle second 14, fill it up with the laser-sensitive such as polyvinyl alcohol or silver nitrate reagent, open light source A(3) and light source B(6), adjust the two position on slide rail, make its two light on same straight line, now can clearly observe light source A(3) the refraction effect of light in transparent liquid storage bottle first 4; Down sliding light source A(3), as light source A(3) incidence angle approach 90 while spending, although refraction angle is also becoming large, but while becomeing greater to a certain angle that is less than 90 degree, become never again large, in transparent liquid storage bottle first 4, there is a refracted ray fan-shaped dark space that is beyond one's reach, the angle of this fan-shaped dark space is only relevant with the index of refraction of solution in transparent liquid storage bottle first 4, on this terminator, put on relevant scale, can read the refractive index of this kind of solution, the general principle of Abbe refractometer can read sample refractive index that Here it is.
Light source C(11) light see through when cuboid glass block 12, light is refracted twice, emergent light is parallel with incident light, can not get can be relevant with refractive index a certain drift angle; As light source C(11) in the time that the upper surface of semicylinder glass block 13 is injected, emergent light no longer becomes a light, and the arc surface of semicylinder glass block 13 all lights, although there is the difference of light and shade, there is no dark space completely. This has explained that why the sample stage of Abbe refractometer is made up of upper and lower two prisms, and the upper prism surface contacting with sample is frosting, and lower prism surface is smooth flat. If sample stage upper and lower surface is all level and smooth, emergent light will, as what demonstrate through cuboid glass block, can not get as the fan-shaped dark space of viewed feature in transparent liquid storage bottle first 4. Frosting is that the upper surface of sample has been become to the light source that 180 new degree omniranges cover, and lower surface is smooth has ensured the feature light that for once reflected, thereby can observe feature dark space.
De-dispersion prism group is directly taken from Abbe refractometer or is carried out the amplification of all directions equal proportion, it is mainly made up of two symmetrical trapezoidal four prisms, two trapezoidal four prisms are separately fixed on two gears, rotate the gear being jointly connected with two gears, two trapezoidal four prisms can rotate along same axis, in rotation process, be equivalent to obtain the prism of different angles, when to a certain angle, can obtain being equivalent to the prism that cross section is parallelogram (when two prisms Central Symmetry). In Abbe refractometer, light is through repeatedly reflecting and will inevitably have dispersion phenomenon, this can make the terminator of feature dark space thicken, thereby is difficult to reading, and De-dispersion prism group can be by regulating prism angle, make dispersed light become directional light, thereby make boundary clear. Open light source D(15), rotate the adjusting knob of De-dispersion prism group 16, can on hot spot receiving screen 17, observe the hot spot of different dispersion degree, allow student clearly observe the definition of hot spot and the relation of dispersion.
