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
Starting with object generation 4.80, both SCOUT and CODE are able to load measured spectra from a Zeiss ThinProcess SQL database. The mechanism is described here.
The small slider windows that can float around on the desktop have been enhanced. You can now easily set the lower and upper slider limits based on the current parameter value: You can choose between +/- a percentage or +/- an absolute value by a single mouse click. There is an option to apply this setting to all sliders.
In addition, you can now easily group all sliders on the screen below a ‘master slider’.
Starting with object generation 4.77 you can generate low and high limits for fit parameters automatically when you generate them – at least for thickness values. In the fit options dialog (File/Options/Fit) you can set a percentage (lower right corner) which is used to compute the low and high limit of the available thickness range. The reference value is the thickness value at the time the new fit parameter is generated.
Note that the automatically generated range is also the range of parameter sliders that are based on fit parameters.
Note also that you can automatically generate thin film thickness values as fit parameters by drag&drop of a layer stack to the list of fit parameters in the treeview. If the list of fit parameters is shown in a view this is certainly the fastest way of generating thickness sliders.
Here is an example showing sliders with limits of +/-5% that have been generated automatically:
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.
Based on WOSP-SUNBLOCK, the WOSP-NOLAB system can be used in glass factories to measure solar reflectance and transmittance (300 … 2500 nm) of large pieces of glass. Total measurement time is about 5 s.
The CODE software used for data acquisition can predict the technical performance data (color, g-value, solar R and T) of arbitrary final glazing products built with the just produced coated pane. All data (spectra, measured and predicted performance data) can be automatically exported to an external SQL database.
Multiple angle reflectance measurements
Glass for buildings and cars may have different appearance with respect to color when the viewing angle changes. The angular dependence of color values is important for the design of glass coatings, and hence it is important to verify that the wanted color values are obtained after coating deposition.
Measurements can be performed using a very simple software interface – they take about 10 seconds.
Results for various samples are collected in a workbook which can be exported as Excel document.
ICCG 12 conference, June 13, 2018, 3 PM, Würzburg, Germany:
Wolfgang Theiss will give a presentation called ‘Up and down – shifting the limits of optical spectroscopy in large area coaters’
Our software packages are powerful – but also complex. The large variety of possible applications and numerous program features are certainly demanding. An introductory training with focus on the user interface and basics of optical modeling significantly shortens the time it takes new users to get going.
Since our users are distributed world wide we have done more and more remote online training during the last years. It turned out that in most cases the number of questions during the sessions has been small, i.e. usually there is not much interaction. With this rather one-directional lectures in mind, we have decided to adapt our working style concerning software training.
Starting in January 2018 we will start to publish a series of recorded lectures, available and free of charge for everybody. New users can follow these sessions at their on speed and whenever there is space in their agenda. In addition to the introduction of training videos we will intensify the FAQ section of our website, hoping that we will give answers to most typical questions that may arise.
If users are interested in deeper discussion we offer to reserve some hours of intense explanations -however, this will not be in real time, and it will not be for free. We will write answers to written questions or prepare short videos, with some time delay between questions and answers. This way everybody can work at a reasonable time of the day, and no information is lost. You can simply repeat a complex procedure and watch it as long as necessary.
We hope that this new concept will prove useful and comfortable for all participants.
