Description

Technical Field

[0001] The utility model relates to the technical field of physical optics double-slit interference experimental lenses, in particular to a double-slit interference single-slit and hole diffraction experimental lens. Background Art

[0002] The double-slit interference, single-slit and hole diffraction experimental lenses are simplified from the double-slit interference experimental instrument. The biggest disadvantage of the original double-slit interference experimental instrument used in the laboratory is that it is clumsy, fixed, and has no flexible operation. The assembly of parts is cumbersome and not suitable for portability and flexibility. The lenses of the original double-slit interference experimental instrument only have single-slit, double-slit and other fixed lenses, which can only meet the most basic experimental requirements of the textbook, cannot meet extended use, and have a limited range of operation. Utility Model Content

[0003] The purpose of the present invention is to provide a double-slit interference single-slit and hole diffraction experimental lens to solve the problems of clumsiness, fixation, lack of flexible operation, complicated assembly parts, and lack of portability and flexibility proposed in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a double-slit interference, single-slit and hole diffraction experimental lens, comprising a first supporting shell, a second supporting shell and an experimental lens, wherein the first supporting shell and the second supporting shell are abutted and connected, and the experimental lens is fixed between the first supporting shell and the second supporting shell, and the surfaces of the first supporting shell and the second supporting shell are connected with pin holes, and the surface of the second supporting shell is fixedly connected with four plug blocks, and the surface of the second supporting shell is provided with a connecting groove, and the surface of the first supporting shell is provided with an open groove, and the inner side of the open groove is fixedly connected with a block, and the inner surface of the second supporting shell is provided with a protruding spring piece.

[0005] Preferably, the experimental lens can be stably fixed inside the first supporting shell and the second supporting shell.

[0006] Preferably, a slot is provided on the surface of the first supporting shell, and the first supporting shell and the second supporting shell are connected by an insert block and the slot.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. By connecting the first supporting shell and the second supporting shell, under the connection of the plug block and the open groove, the plug block and the stop block are used to achieve a snap connection effect between the first supporting shell and the second supporting shell, thereby realizing a supporting effect on the position of the experimental lens in the first supporting shell and the second supporting shell, and fixing it with a protruding spring piece on the inner surface, realizing a supporting effect on the position of the experimental lens in the first supporting shell and the second supporting shell. By opening and closing the first supporting shell and the second supporting shell, it is convenient to replace the experimental lens. The double supporting shell movable buckle connection is adopted, and the internal step size positioning of the supporting shell is controlled. By matching the external size of the experimental lens, various experimental lenses with different contents can be replaced at will. Under the connection of the plug block and the jack, the position of the experimental lens in the first supporting shell and the second supporting shell is fixed and supported. Under the protection of the first supporting shell and the second supporting shell, contamination of the surface of the experimental lens is avoided when taking it out. Moreover, under the anti-slip effect of the frosted rough treatment on the surface of the supporting shell, it is convenient to clamp, place and support various experimental instruments, thereby improving the friction and stability of its clamping.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-4 , an embodiment provided by the utility model:

[0016] The double-slit interference, single-slit and hole diffraction experimental lens includes a first supporting shell 1, a second supporting shell 2 and an experimental lens 3. The first supporting shell 1 and the second supporting shell 2 are abutted and connected, and the experimental lens 3 is fixed between the first supporting shell 1 and the second supporting shell 2. The surfaces of the first supporting shell 1 and the second supporting shell 2 are connected with pin holes 4, and the surface of the second supporting shell 2 is fixedly connected with four plug blocks 5. The surface of the second supporting shell 2 is provided with a connecting groove 6, and the surface of the first supporting shell 1 is provided with an open groove 7. The inner side of the open groove 7 is fixedly connected with a block 8, and the inner surface of the second supporting shell 2 is provided with a protruding spring piece 9.

[0017] Furthermore, the experimental lens 3 can be stably fixed inside the first supporting shell 1 and the second supporting shell 2. As long as the experimental lens 3 meets the external dimensions, it can be stably installed on the air-avoiding step opened on the inner surface of the first supporting shell 1. The content of the experimental lens 3 can be arbitrarily changed to single slits, double slits, multiple slits, double holes and various holes.

[0018] Furthermore, a slot is provided on the surface of the first supporting shell 1, and the first supporting shell 1 and the second supporting shell 2 are connected by engaging the insert 5 with the slot. The experimental lens 3 is manufactured by an optical photography process and is completed by outputting a PET grating lens made of a high-precision laser printer. The physical precision of the slit width and spacing of the grating lens content is controlled within 0.01 mm through the processing technology, which exceeds the precision of the traditional slit cutting process on the metal plate and far exceeds the precision of the coating and slit processing process on the glass quartz plate. In the experiment, the higher the precision of the slits and holes in the grating lens, the more accurate the experimental data can be, the lower the error rate of the experimental results can be, and the better the accuracy of the experiment can be met.

[0019] Working principle: When the experimental lens 3 is replaced or disassembled, under the connection between the second supporting shell 2 and the insert block 5, the first supporting shell 1 and the opening groove 7 are connected, the connecting groove 6 and the opening groove 7 are separated, and the insert block 5 and the slot on the first supporting shell 1 are separated to complete the replacement operation of the experimental lens 3. Under the action of the protruding spring piece 9, the protruding spring piece 9 and the experimental lens 3 are plugged and connected to achieve the positioning and support effect of the experimental lens 3 in the second supporting shell 2 and the first supporting shell 1.

[0020] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
