New import routine for old Optoplex IIC files

Starting with object generation 4.91 the SCOUT and CODE software packages can import exsitu spectra reading text files generated by the Zeiss Optoplex IIC software. The routine can be called executing the menu command Actions/Spectra/Import/Import all spectra from an Optoplex IIC exsitu file.

Please note that in this format the wavelength range of the measured data always starts at 380 nm. Wavelength increment from point to point is 5 nm.

Spectral data are stored in % by Optoplex – you have to set the option to automatically divide incoming data by 100 in all receiving spectrum objects.

GenetiCode update: Master parameter optimization

Starting with version 1.40 GenetiCode can optimize master parameters of the underlying CODE configuration. Similar to the handling of thickness values, you have to specify a range of possible values [minimum … maximum] for each selected master parameter. During the evolution GenetiCode will then try to find the best solution.

Master parameters can be used to compute model parameters by the evaluation of user-defined expressions. You can use this mechanism to express restrictions of the design like one layer must have twice the thickness of another layer, or you can introduce temperature as a master parameter that governs optical constants and thickness values of a multilayer coating.

GenetiCode package 1.40 comes with an updated PDF that explains how the optimization of master parameters has to be defined.

Password protected views (object generation 4.88)

SCOUT and CODE are more and more used for routine work, often being operated by users not familiar with these software packages. You can protect the configuration against unwanted modifications by setting a global password (main menu: File/Options/Password). This option is available for a long time already.

In complex methods using several views you can now define individual passwords for each view. This way you can avoid every user being able to access every view. A typical scenario would be a measurement system that shows a few control elements in a view for routine measurements, and more details and controls for expert users in an advanced view. If the ‘expert view’ is password protected it can be seen and used by selected users only.

Additional illuminants

Color computations were limited to illuminants A, D65 and C up to now. Additional illuminants could be imported and used for computations – however, this option was somewhat hidden and very likely overseen by many users.

With have now, starting with object generation 4.86, implemented 15 additional illuminants (D50, D55, D75, F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12).

Parameter fluctuation

Doing a parameter fluctuation you were limited to a maximum of 250 realizations. Starting with object generation 4.86 this limit has been increased to 65000.

Since computations with many iterations take quite a long time the status bar at the bottom of the main window (if not visible, show it by hitting the key ‘s’ on your keyboard) shows the progress of the work.

Results of the parameter fluctuation are stored in the workbook. We recommend to store the workbook to a file and open this file with Excel in order to further process the data. The workbook component integrated in SCOUT or CODE is not very convenient to handle large amounts of data.

New fit option

We have included a new fit option which helps to increase the speed of analysis in time critical applications: In methods which use pre-fit sets in the list of fit parameters you can now include the current fit parameter values in the pre-fit search. This eventually avoids many fit iterations if differences between consecutive measurements are small.

The new feature can be turned on or off in the dialog of fit options.

 

Climate settings, window tilt angle, pane absorption and temperature computations

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
