The project aims to design a glass system that utilizes refraction and capillarity phenomena to change the optical haze of the system without electricity, heat, light, etc. The objective is to differentiate the widespread technology and obtain a basic, low-cost product.
In our setup, (5×5) cm2 ordinary and frosted glasses were used, where we could see different liquids rising between the glasses. The liquids being able to rise easily between the glasses and the adjustable angle between them formed the basis of the design.
Our integrating spheres were made of styrofoam and then obtained from 3D printer to make the haze measurement more sensitive. Experiments were continued with the premade sphere provided by the university laboratory. The measurements were made with simple materials that could be easily obtained and showed that glasses that can change optical haze could be obtained at low costs. When the results of the measurements taken with the glass and film materials that were obtained from the R & D departments, the average accuracy rate of the integrating spheres we designed was 94%.
The cost of switchable glasses is high because they utilize electricity, heat, light. In the design, which cost an average of $10, the immersion oil, which prevents the haze effect caused by the frosted glass, gave the clearest appearance.
The results of our experiments may lead to the development of a product that is simpler and can be used as a curtain for interior and exterior decoration of buildings with low cost.
