Abstract: A method for measuring the thickness of glass containers includes the following steps: choosing to measure the radiation emitted by the container from a first side and a second side of the container diametrically opposite to each other; choosing to measure the radiation emitted by the container in a first spectral band in a range between 2,800 nm and 4,000 nm and in a second spectral band; simultaneously measuring, from each side of the container, the intensity of the radiation coming from the walls in the first spectral band and in the second spectral band; and determining at least the thickness of the first wall and of the second wall (22), from the measurements of the intensity of the radiation coming from the first wall in the first and second spectral bands and from the second wall in the first and second spectral bands.
