For the production of “smart glass” Octoglass uses an original polymer electrochrome, which is based on the redox reactions of organic molecules under the action of an electric voltage. There are a number of reasons why we use this type of material. This technology makes it possible to achieve consumer characteristics both in color and contrast, and in the speed of switching states. There is a black shade of toning, which is most in demand among the consumer, as well as the presence of devices of other shades, which can be implemented at will. Another factor in favor of the organic polymer can be called the fact that it is possible to change the lower and upper limits of light transmission within a single contrast change delta.
