Embodiment

[0013] The continuous white light source 2 emits continuous visible light white light, which is irradiated on the transparent substrate 4 coated with the transparent medium ball 3, and the substrate holder 5 can move back and forth along the emission direction of the point light source, and is on the right side of the transparent substrate (point The transmitted multilevel full-circle rainbow can be observed on the opposite side of the light source, while the multilevel rainbow can be observed on the left side of the transparent substrate (the same side as the point light source). The variation of the rainbow diameter can be observed by moving the substrate support 5 back and forth. For example, the positions of the observer and the point light source remain unchanged. The diameter of the circular rainbow will grow larger.

[0014] When a convex lens is added between the point light source and the medium ball, the rainbow can be projected on the surface of a distant wall or bu...

Abstract

The invention discloses an observable and projectable full-circle multistage rainbow apparatus which comprises a light source support, a continuous white light source, a transparent medium ball, a transparent substrate, a substrate support and a base plate, wherein the light source support is fixed on the base plate, the continuous white light source is fixedly connected with the light source support, the substrate support is fixed on the base plate, the transparent substrate is fixed on the base plate, the single layer of the transparent medium ball is uniformly laid on the transparent substrate, the height of the continuous white light source is the same with the center of the transparent substrate, the continuous white light source lights up the transparent substrate, and the distance between the continuous white light source and the transparent substrate is adjustable. A common rainbow demonstration apparatus can not display real principles of a natural rainbow, has too much tools, is low in work efficiency and is limited by observation angles. The full-circle multistage rainbow apparatus clearly shows the real principles of a natural rainbow, improves rainbow generation efficiency, lowers labor intensity on a certain level, improves rainbow observation levels, and has promising market for school demonstration experiments and rainbow projection devices.

Description

technical field [0001] The invention relates to a method and device for optically manufacturing a full-change rainbow, in particular to an observable and projectable full-circle multi-level rainbow device. Background technique [0002] At present, the devices for making rainbows include grating spectroscopic devices or prism spectroscopic devices, reflective devices, saline solution tanks and spray devices. Although these methods can produce rainbows, grating spectroscopic devices or prism spectroscopic devices, reflectors, and saline solution tanks cannot reflect the physical mechanism of rainbows in nature; and spray devices cannot fully demonstrate the characteristics of rainbows in nature. It has problems such as complex structure, unstable phenomenon and poor usability. The full-circle multi-level rainbow device of the present invention emits light through a point light source to illuminate transparent nanometer or micron balls to generate a full-circle multi-level rai...
