Abstract: A device for controlling a production system for planar or strand-shaped bodies comprises a measurement region and a conveying apparatus configured to convey the body through the measurement region. A transmission apparatus is configured to irradiate the body with measurement radiation in the measurement region. A detection apparatus is configured to detect the measurement radiation reflected by the body. An evaluation apparatus is configured to use the measurement radiation detected by the detection apparatus to determine at least one of: (1) a refractive index of the body; and (2) an absorption of the measurement radiation by the body. A control apparatus is configured to control at least one production parameter of a production system based on the at least one of: (1) the refractive index of the body; and (2) the absorption of the measurement radiation by the body.
