Optoplex spectrum scanner: New version

A new version of the scanner has been released. We have verified that this one can process reflectance measurements taken at 55° angle of incidence, in addition to the ‘normal’ transmission and reflectance spectra recorded at 8° angle of incidence.

Make sure that your BREIN product contains 4 spectra, and that you enter Optoplex names correctly in the conversion tables ‘BE assignment’ and ‘Spectrum nicknames’: Sometimes the database column ‘Resultname’ is ‘OFR155° SB Reflection’, and sometimes it appears as ‘OFR155° SB Reflection Glass’.

 

 

Inspection of historic fit results: New BREIN feature

The prediction feature of BREIN transfers the latest fit results and spectra to an internal CODE instance. This can be used to do various kinds of computations, based on the properties of the pane that was investigated last.

In a similar way the new ‘Inspection’ mechanism re-loads historic fit results (and the spectra that were used to obtain these numbers) to a separate CODE instance. This can be configured to let the operators verify the fit results and try what happens if some parameters were modified.

For details please see the updated documentation (page 55 at the moment).

 

ISO 52022-3 (2017) integration

The computation of the total solar heat gain coefficient (g-value) following the rules of standard ISO 52022-3 (2017) has been implemented. The procedure takes into account the temperature change of panes and gases due to absorption and re-emission of solar radiation. The absorbed solar power and the final temperature of each pane are side-results of the routine and are available in addition to the g-value.

Prediction page upgraded

The BREIN prediction page now forwards mouse clicks and mouse moves to the underlying CODE window. This opens the route to interactive operator work.

However, the prediction page of BREIN is updated every second only. This means the user interface is not as responsive as that of CODE itself.

New Optoplex SQL scanner

We have developed a new scanner software that connects the Zeiss Optoplex SQL system to BREIN. The program scans database tables for inline and exsitu spectra and feeds new spectra into the corresponding BREIN input folders.

More flexible prediction trigger

The definition of the trigger event that initiates the re-computation of the prediction page has been improved: You can now specify a range of x, y or z values, in addition to fixed values.

A setting of “1500 … 1600” for y means that the trigger event is fired whenever the condition 1500<=y<=1600 holds. This new feature is useful to handle traverse systems which do not measure at exactly the same positions when scanning a sample.

You can still set unique values like “1567” for the x, y or z coordinates.

Poor graphics appearance on some monitors – how to avoid …

On monitors with high dpi values (small pixel size) Windows 10 sometimes decides to scale text output on graphics pages. In this case main view graphics of SCOUT, CODE and BREIN may look ugly, like on low resolution screens.

If this happens on your computer you can right-click the program file (scout.exe, code.exe or brein.exe) and select ‘Properties’ (or ‘Options’) and then open the tab ‘compatibility’. Check the option ‘Disable display scaling on high DPI settings’ as shown below:

high_dpi_settings

That should solve the problem.

Thanks to S. Eraslan for pointing out this solution!

Color visualization improved

The generation of sRGB values for color visualization on computer displays has been improved. Most colors look significantly brighter now. Be aware, however, that you can still not fully trust color visualizations unless you have a calibrated screen.
