This application claims priority benefit to Taiwan Invention Patent Application Serial No. 111129628, filed on Aug. 5, 2022, in Taiwan Intellectual Property Office, the entire disclosures of which are incorporated by reference herein.
The present invention relates to an exchangeable optical principles demonstrating kit, in particular to an exchangeable optical principles demonstrating kit that is configurable by exchanging and attaching different accessories to differently configure into an optical interference principle demonstrating device or an optical pinhole principle demonstrating device.
In the field of basic science education, the teaching of optical principles has always been very fundamental and important. The principles and knowledge of, from the basic light propagation characteristics, light refraction phenomenon, light reflection phenomenon and pinhole imaging, to the advanced optical electromagnetic spectrum and spectrometer, etc., have always been the focus of the teaching of optical principles.
Currently, in the traditional teaching process of optical principles, educators usually explain these optical principles to learners by means of showing drawings together with the explanation of mathematical formulas. Some simple teaching aids have been used by good teachers, so that learners can see the characteristics of these light principles and the actual phenomena in real in addition to the abstract drawings and formulas.
As far as the teaching aids of spectrometer are concerned, the commonly used teaching aids of spectrometer usually have a larger volume. Some versions of the teaching aids are a bit bulky, and are usually expensive and not easy to obtain and maintain. If the teaching aids are in simple versions made by DIY hand-made manner using the materials in life, such as optical disks, buckets, etc., such teaching aids are generally not precise and durable enough. The teaching aids of pinhole imaging experiment have the similar situations.
But most importantly, no educator has ever thought about integrating the two unrelated teaching devices, i.e., the teaching aids of spectrometer and the teaching aids of pinhole imaging, to a certain degree, and further making them into a more lightweight and palm-sized version of teaching aids.
Hence, there is a need to solve the above deficiencies/issues.

The present invention is a multi-functional optical experimental teaching aid, which can be used for pinhole imaging and visible light spectrum experiments. The two experiments share the same main structure, and different purposes of experiments can be achieved by replacing key components. The main structure is a design of a retractable sleeve structure, which is used to adjust the optimal vision distance to facilitate the observation. A dark room is formed by a double-box type sleeve structure, where the inner box is light impermeable to facilitate optical experiments. The key components are grating magnetic connectors, pinhole magnetic connectors, slit magnetic connectors, and screen magnetic connectors. The design principle of these magnetic connectors is to quickly replace the key components by using the magnetic attraction, so as to form a pinhole imaging or spectrometer teaching aid.
The present invention provides a retractable structure in the design of sleeves, and magnetic attraction devices are arranged at the front and rear. After assembly, a composite structure that is sealed and light impermeable can be formed. There are openings disposed at the front and rear of the structure, one of the openings is the light entrance port and the other of the openings is the observation port. By arranging the pinhole magnetic connectors on the light entrance port, aligning with a specific scene, and arranging the screen magnetic connectors on the observation port, the image of the scene on the screen can be seen. By arranging the slit magnetic connectors on the light entrance port, aligning with a specific light source, and arranging the grating magnetic connectors on the observation port, the spectrum of the light source can be seen.
In the present invention, not only the two experiments of the pinhole imaging and the visible light spectrum are designed into the same structure, but also the key components can be quickly replaced by using the principle of magnetic attraction, which can change the type of experiments, such as but not limited to, pinhole imaging or spectrometer, or can change observation parameters, such as but not limited to, pinholes having different aperture sizes, pinholes having different shapes, grating films having different densities of fringes, slit sheets having different slit widths, and so on, for scientific exploration.
