Once youhave optimized the design of your coating product with respect to angular variation of color you have to check if it really performs as CODE predicts.
The prototype described in this section will do the job: You can record absolute reflectance and transmittance spectra in high quality for the range 8° to 85° of the angle of incidence. The 85° are possible only for thin samples, with thickness below 5 mm. You do not need a calibration mirror since the 100% reference measurement can be done with light source and detector facing directly opposite to each other.
WOSP-ART consists of a light source and a detector mounted on arms which can be rotated individually. Spectra are recorded for the wavelength range 380 … 1100 nm. Extensions to the UV (down to 280 nm) and the NIR (up to 2500 nm) are possible.
Measurements are performed using our CODE software which can export results to data files or external SQL databases.
Here is a video demonstrating the operation of WOSP-ART.
We have updated the documentation of the connectivity to external SQL databases. SCOUT and CODE can save configurations, materials and measured spectra as well as fit results. The required table structure is generated automatically.
Below is the link to the relevant section of the SCOUT manual:
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.
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:
That should solve the problem.
Thanks to S. Eraslan for pointing out this solution!
Starting with object generation 4.58, SCOUT and CODE can export data like fit parameters or values of optical functions (in CODE also integral quantities) to external SQL databases. If you have done a measurement with a spectrometer system and performed a fit of a model you can send the results to your company database.
We have implemented an ADO database connection which lets you contact Microsoft, Oracle and Informix databases. Before you can do that the corresponding client software has to be installed on your computer.
Which values are exported to which columns of the open database table is defined in scripts. Scripts are view elements which appear like a button in the main view. When clicked they execute a sequence of commands, including calling other scripts.
XRR objects in CODE and SCOUT can now import measured XRR data reading xrdml files.
With version 4.56 we have removed a bug in master models for optical constants. Saving a successful model and re-loading it could lead to a strange mix-up of parameter values in some situations, leaving the poor user with a useless configuration. We recently taught CODE and SCOUT to correctly count master and slave parameters – saving and loading should work now.
We have fixed a (small) incorrect conversion of X, Y, Z color coordinates to sR, sG and sB computer screen values when the field of view has a cone angle of 10°. The routines for 2° cone angles have not been changed.
The output of sound insulation values for glazing products has been improved: Rw, Ra, Ra,tr, C and Ctr are now available as integral quantities.
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.
