We have added optical functions which return statistical numbers based on cell values in the workbook or batch control windows. They are useful if you determine thickness profiles and want to display average thickness, minimum and maximum values, as well as standard deviation from the average.
The functions are explained here:
Depending on the configuration, it could happen that the main application brein.exe generated a *.csv file for each processed pane in the BREIN program folder. These files were meant to be generated for BREIN viewer, in the designated transfer folder, but happened to be generated even if BREIN viewer is not used at all.
We have removed this error in the latest version of brein.exe.
A bug in the computation of averaged parameter values in operator views has been fixed.
We have included a new fit option which helps to increase the speed of analysis in time critical applications: In methods which use pre-fit sets in the list of fit parameters you can now include the current fit parameter values in the pre-fit search. This eventually avoids many fit iterations if differences between consecutive measurements are small.
The new feature can be turned on or off in the dialog of fit options.
The Optoplex scanner has been updated – we have improved several small details like the appearance of the database tables. As a new feature, sheet resistance values can now be imported into BREIN in order to be displayed.
We have upgraded several CODE functions related to the technical performance of glazing products.
You can now compute solar pane absorption and pane temperatures for up to 6 glass panes.
The list of integral quantities in CODE features new menu items (in File/options):
- set global climate parameters used for U-value, g-value and temperature computations
- set the window tilt angle for all U-value, g-value and temperature computations
You can display climate values using labels in a view with the following names:
- ‘selected_climate’ (shows the name of the climate)
- ‘selected_climate_parameters’ (shows values of outside temperature, external heat exchange coefficient he, inside temperature, internal heat exchange coefficient, solar power
- ‘selected_climate_ISO52022’ (shows the name of the climate settings for ISO 52022-3 computations)
- ‘selected_climate_parameters_ISO52022’ (shows values of outside temperature, external heat exchange coefficient he, inside temperature, internal heat exchange coefficient, solar power, used for ISO 52022-3 computations)
You can display the value of the window tilt angle using a label called ‘window tilt angle’.
Finally, you can call the following new script commands to open user dialogs in the main view:
- edit climate
- edit window tilt angle
We have made the import of measured traverse spectra from the Zeiss SQL database more flexible. Up to now the scanner processed all new spectra not analyzed by BREIN. In order to do so it sends an SQL search command to the Optoplex Q database filtering out spectra with IDs larger than the last processed ID,
You can now inject more search criteria into the SQL search command filtering in a more complex manner. In order to inject additional search conditions you have to add 2 lines to the optoplex_sql_spectrum_scanner,ini file, The first line is ‘Optoplex Q where phrase’ and the second line the injected SQL fragment. Here is an example:
Optoplex Q where phrase
and (measpointindex = 1 or measpointindex = 10)
When you re-start the scanner it will only process spectra recorded at measurement positions 1 and 10 – all other spectra are ignored.
We have copied our tutorial videos to a second platform which is available in China. Click the following link:

The table of results can now be filtered: You can type in a pane ID or select a bright eye (or both) and check the ‘filter’ option – the table will then show results for the selection only. Unchecking the filter option brings you back to the display of all results.
An error in the computation of carrier mobility for the extended Drude model has been removed. The new (hopefully correct) values are all smaller than the previously computed values.
