The BREIN software has been developed to assist operators controlling thin film production devices. Optical spectra like transmittance, reflectance or ellipsometry data are recorded at appropriate positions in the production equipment. These stations are called 'Bright Eyes'. BREIN (which stands for BRight Eye Inspection Network) analyzes the measured data. In the simplest cases color coordinates are computed and displayed. In more advanced solutions an optical model is fitted for the currently produced coating, and information about film thicknesses and film composition is extracted. This information is displayed to the operators in order to simplify decisions about modifications of the settings of the deposition devices.
Note the objects in the sketch below which shows a typical BREIN application. Window panes are entering the deposition line from the left. After each important group of deposition devices (later on called DD) there is a bright eye station (BE1, BE2, ...) inspecting what has been produced. The measured data are stored in a central storage in the network, accessible by all participating PCs. One or more computers do the analysis work and store the results in the central storage. The main BREIN application collects all results in a database, and provides appropriate operator displays.
Spectroscopic hardware may be delivered by various instrument builders. The BREIN software is made by W.Theiss Hard- and Software. This part of the documentation deals with the software only.
