A large circle of 4c could be used for wine glasses.
  • the recognition of the marking 4 can be such that even in the case of the existing transparency of the glasses, a distinction which is noticeable for the arithmetic unit 6 is given. This can be achieved, for example, by different optical properties, such as refraction, reflection or absorption of light (for example the light source 20).
