You need an optimal installation and products that are compatible with the mirror material to be able to enjoy a distortion-free view in the mirror every day in the long term.
Everyday mirrors have a flat surface made from an aluminum-coated glass plate. They are mainly used in households. Besides these there are also optical mirrors. These are designed so that the reflecting surface itself is usually applied to the front of the base material. If parallel incoming rays from the entire mirror are to be focused on one point, a parabolic mirror must be used, as they are in solar thermal power plants for example.
Besides the ‘traditional’ way of manufacturing mirrors, there is an environmentally-friendly production method that does not require the use of copper sulfate. In addition, only lead-free paints with significantly fewer ammonia salts are used here.
