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:
In object generation 4.97 we have implemented a new mechanism to pass error messages from SCOUT and CODE to OLE automation clients.
While it runs the OLE server (i.e. SCOUT or CODE) collects error messages in a list. We have introduced a view object (type ‘Error messages view’) to display the current list of error messages in a view.
Any OLE client (LabView, Excel, …) can retrieve information about the number of error messages, their type and text content. There is also a classification to separate critical errors and warnings. Once the OLE client has finished error handling it can clear the list in the OLE server.
There are new script commands to write text and numbers to the workbook. The number to be written as well as row and column of the write action may be computed using user-defined expressions. You can refer to master parameters, fit parameters, optical functions and integral quantities in these expressions.
In the opposite direction, we have implemented new optical functions to compute average and standard deviation of rectangular blocks of cells, both in the workbook and the batch control window. As object names you have use the terms ‘workbook’ or ‘batch control’. The argument of the function call must specify the name of the worksheet as well as the start row and start column, and the end row and end column – all separated by commas.
In addition to optical constants and spectra, the menu command File/Report/Object data to workbook now (you need object generation 4.94) exports the layer stack definitions.
In CODE the integral quantities are added as well.
After using the command ‘Prepare new results page for Von Ardenne exsitu files’ the assignment of spectra and positions on the glass was not correct. This has been fixed.
Starting with object generation 4.91 the SCOUT and CODE software packages can import exsitu spectra reading text files generated by the Zeiss Optoplex IIC software. The routine can be called executing the menu command Actions/Spectra/Import/Import all spectra from an Optoplex IIC exsitu file.
Please note that in this format the wavelength range of the measured data always starts at 380 nm. Wavelength increment from point to point is 5 nm.
Spectral data are stored in % by Optoplex – you have to set the option to automatically divide incoming data by 100 in all receiving spectrum objects.
We have implemented the new script command ‘import all spectra from a von ardenne exsitu file’ which shows the dialog to load spectra from a Von Ardenne exsitu file.
SCOUT and CODE are more and more used for routine work, often being operated by users not familiar with these software packages. You can protect the configuration against unwanted modifications by setting a global password (main menu: File/Options/Password). This option is available for a long time already.
In complex methods using several views you can now define individual passwords for each view. This way you can avoid every user being able to access every view. A typical scenario would be a measurement system that shows a few control elements in a view for routine measurements, and more details and controls for expert users in an advanced view. If the ‘expert view’ is password protected it can be seen and used by selected users only.
Doing a parameter fluctuation you were limited to a maximum of 250 realizations. Starting with object generation 4.86 this limit has been increased to 65000.
Since computations with many iterations take quite a long time the status bar at the bottom of the main window (if not visible, show it by hitting the key ‘s’ on your keyboard) shows the progress of the work.
Results of the parameter fluctuation are stored in the workbook. We recommend to store the workbook to a file and open this file with Excel in order to further process the data. The workbook component integrated in SCOUT or CODE is not very convenient to handle large amounts of data.
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.
