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.
WOSP-MAC (multiple angle color sensor) is a lab instrument that measures color values at fixed angles of incidence of 30°, 45° and 60°.
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.
