Our new WOSP-LEDO light source generates a homogeneous area of light emission, covering the spectral range 270 … 900 nm. It uses LEDs only – small power, long lifetime.
You can point a collimated field of view of an array spectrometer to the center of the light source and record transmittance or reflectance spectra in lab quality, within a fraction of the time a lab instrument would need.
The following transmittance spectra (100%, 0%, Schott Borofloat glass) have been recorded in less than 1 second, with a distance of about 1 m between light source and detector:
Zooms into the 0 and 100 percent spectra show excellent spectral quality:
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.
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.
