Description

Technical Field

[0001] The utility model belongs to the field of glass structure equipment, in particular to a glass structure with variable refractive index. Background Art

[0002] In the field of optical imaging and display, better imaging effects and display quality can be achieved by changing the refractive index of glass. However, the refractive index of most common glass structures is immutable and has many disadvantages. Due to its fixed refractive index, it is impossible to flexibly adjust the propagation characteristics of light, which limits the optimization of optical performance in many application scenarios. For example, in optical instruments, fixed refractive index glass cannot adjust the refractive index in real time according to different observation requirements and environmental conditions, resulting in limited imaging quality, and chromatic aberration, aberration and other problems are difficult to effectively solve. This is due to the fixed composition of the glass material and the fixed molecular structure after curing. To address these shortcomings, the conventional method is to use glasses with different refractive indices for combination. However, the combination of glasses with different refractive indices often increases the volume and weight of the system, and the interface reflection and refraction between different glasses will cause the loss of light energy, so it is necessary to propose a new structure to solve the above technical problems.

By arranging refractive index matching layers composed of titanium dioxide film and silicon dioxide film on the upper and lower surfaces of the glass body, the basic refractive index characteristics of the glass can be optimized to a certain extent, and when the electrochromic thin film layer changes under the action of the electric field, the refractive index matching layer helps to coordinately adjust the overall refractive index, thereby achieving a wider range and more precise refractive index regulation.

[0020] See also Figure 1 As the first embodiment of the utility model: the frame body 100 is a rectangular parallelepiped structure, the structure of the reinforcement frame 110 is the same as that of the frame body 100, the thickness of the reinforcement frame 110 is less than the thickness of the frame body 100, and the frame body 100 and the reinforcement frame 110 are installed on the right edge of the upper surface of the reinforcement frame 110. The power controller 120 is a MOSFET power controller 120;

[0021] The power controller 120 is electrically connected to the electrochromic film layer 220 . A glass body 200 is installed at the center of the frame body 100 . The material of the glass body 200 is borosilicate crown glass.

[0022] When in use, the reinforcement frame 110 installed on the front and rear surfaces of the frame body 100 can significantly increase the overall mechanical strength of the glass structure. During daily use, transportation, and installation, it can better resist external impacts, collisions, and extrusions, and reduce the risk of glass breakage and damage. The frame assembly is not limited to being installed on the outer surface of the glass assembly. The glass assembly can be used alone, but attention should be paid to the installation position of the power controller 120.

[0023] See also Figures 1 to 3 , as a second embodiment of the utility model: the thickness of the refractive index matching layer 210 is less than the thickness of the electrochromic thin film layer 220, and the refractive index matching layer 210 is composed of three layers of titanium dioxide thin films 211 and three layers of silicon dioxide thin films 212;

[0024] The three layers of titanium dioxide film 211 and the three layers of silicon dioxide film 212 are staggered with each other, the top layer of the refractive index matching layer 210 is the titanium dioxide film 211, and the bottom layer of the refractive index matching layer 210 is the silicon dioxide film 212;

[0026] When in use, when the user needs to change the refractive index of the component when using the glass component, the user first starts the power controller 120 on the upper surface of the frame component, and the power controller 120 is powered on to supply power to the electrochromic film layer 220 (the electrochromic film is composed of an electrochromic layer, an ion conductive layer and a counter electrode layer 230. The electrochromic film and the power controller 120 are prior art, and their specific working principles are not described here. When the MOSFET power controller 120 is powered on, current is applied to the electrochromic film through the circuit. At this time, the tungsten oxide (WO3) electrochromic film, when a forward voltage is applied through the power controller 120, the cations (lithium ions, hydrogen ions) in the electrolyte will migrate through the ion conductive layer into the electrochromic layer (WO3 layer) under the action of the electric field. These cations enter the WO3 lattice to form tungsten bronze (such as H X WO3、Li X WO3), the optical properties of the film change, which is manifested as a darkening of the color, and at the same time, optical parameters such as the refractive index also change. At the same time, when the power controller 120 applies a reverse voltage, the cations escape from the electrochromic layer, and the film returns to its initial state, the color becomes lighter, the refractive index is restored, etc.), and the refractive index of the glass can be changed by matching the refractive index matching layer 210. By arranging the refractive index matching layer 210 composed of a titanium dioxide film 211 and a silicon dioxide film 212 on the upper and lower surfaces of the glass body 200, the basic refractive index characteristics of the glass can be optimized to a certain extent, and when the electrochromic film layer 220 changes under the action of the electric field, the refractive index matching layer 210 helps to coordinately adjust the overall refractive index, thereby achieving a wider range and more precise refractive index regulation.
