No import routine

There is no import routine for my spectra. How can I get my data into the software?

If there is not import routine for your type of spectra, you should check first if your spectrometer system can export the spectra in a format which is recognized by our software. Most spectrometer packages can generate tables of the measured data in ASCII format which can be imported using the ‘xy-format’.

In desperate cases you can ask us to write an import routine for your type of spectra. We can do this if we get a description of the data format, and if it can be done with a reasonable amount of effort.

Batch fit of Optoplex NGQ and Von Ardenne exsitu files

The Zeiss Optoplex NGQ software can create *.csv files which contain all measured spectra of an exsitu traverse scan. Von Ardenne exsitu files have a similar content.

You can now easily fit the spectra of all probehead positions using the batch control window. Once you have a good fit routine, you can execute the batch control menu command “Prepare/New batch fit”, followed by the command “Prepare/New results page for Optoplex NGQ file” or “Prepare/New results page for Von Ardenne exsitu file”. Then press “Go”.

CODE will fit all spectra and write the fit results to the page “Results”. Using view objects of type “Batch control graph (rows)” you can visualize obtained  thickness profiles, for example.

New ellipsometry import routine

Ellipsometry objects can now import data saved in *.pae files by SOPRA ellipsometers.

Although the angle of incidence is stored in such files the value of the angle of incidence of the ellipsometry object (which is used for the computation of simulated data) is not changed. This way you can import data measured at 70°, for example, and still do the computations for 69.9° – a small difference is sometimes  necessary to correct for experimental uncertainties.

Updated import routine

The import routine for text files (xy-format) has been improved to allow to read data from files with several data columns. If you use this routine in batch operations or through OLE automation, you can now specify the column to read from as input option. Option = 1 means to read from the first column, option = 3 reads from the 3rd.
