- The central wavelength for the surrounding variation group is now preserved and kept as configured in the general configuration dialog.
- Login and logout from the User account (Windows) can cause internal changes to the decimal separator setting in OTF Studio with undesirable results. Fixed. The internal setting for the Decimal separator remains constant.
24.44
1. Interface enhancements:
- Right-click drop-down list added to History/Collection panels with main related commands.
- Capacity of History and Collection panels can be also controlled with the right-click drop-down. Possible capacities are 100, 250, 1000, 2500 items.
- Open Project function now also sets the Mode of OTF Studio according to the mode saved in the Project file.
- Size of buttons in the Model builder decreased to avoid multi-line layout.
- Better updates of U-, g-values after change of configuration or settings.
- Fit operation (RE mode) checks that at least some model is selected, and if not, an error message is displayed. It allows to avoid possible confusion on not working fit procedure.
2. Enhancement of design algorithms:
- Gradual Evolution and Needle Optimization methods were further improved to accelerate convergence.
- The Multi-Start algorithm was enhanced to prevent thick solutions.
3. Formula to Table convertor has been implemented to the Substrate editor and Material editor.

24.41
1. Batch processing for Position-type measurements in RE mode has been developed. When Position-type measurement data and a selected coating/layer model are loaded, the Batch tab on the Reverse Engineering Model Builder panel allows you to apply the model to all positions simultaneously. The results (correction factors) can be easily exported to a text file or Excel.
2. Fast export tab has been added into Design Editor allowing you to export the design into a *.txt format of X/Y type.
3. Enhancements:
- Synthesis with inhomogeneous layers enhanced and converges faster
- Mode switching has been made more convenient: there’s no need to decide whether to save the current project file. The modified status is automatically preserved across all modes.

2. Freeze (curve) option has been added to the Evaluation panels (AS mode). It allows to keep existing theoretical spectral curves in the plots even when the design or configuration changes.
3. Tooltips have been significantly improved: they display better the numerical values for each of the theoretical curves. Now, the numerical values of the spectral characteristics when you hover the cursor over the relevant point are displayed automatically, i.e., "old tooltips" are active by default.
4. Tooltips and Freeze in RE and CH: both features are accessed also through the right-click drop-down list of Fitting plots.
5. Significant enhancement of docking: Docking of panels and plots is now more flexible than ever, allowing for any customizable layout. Plots and panels can be arranged vertically and horizontally in any order. Very complex layouts are possible now.
6. The Design Recipe feature has been integrated into RE mode. This feature allows for the automatic saving of designs after reverse engineering, with adjustments for layer thickness correction factors (Results ribbon → Recipe). The thicknesses from the Recipe can then be used for the next deposition run. After this run, reverse engineering can be performed again to determine any new errors in layer thicknesses. The Recipe design should be loaded as the starting point for this process. The reverse-engineered design can be saved as the Recipe for the subsequent deposition run. During the saving process, Recipe designs are automatically named in a way that makes it easy to track the entire sequence of recipes. The Design Recipe feature significantly speeds up the workflow.
7. Export to LightTools Design and LightTools Spectra (Coating) have been implemented.
8. Now, LMR export is supported in OM mode only, since for LMR the runsheet of monitoring is required. Therefore non-supported LMR export tabs have been removed from the Results ribbons in AS, CH, and RE modes.
9. Interface improvements:
- Selection of target spectral characteristics in the Target Editor is now more convenient: you can select an item with just one click, whereas previously, two clicks were required.
- Import from Catalogs is more convenient: the first item is not selected on initial display of the Import panel.
- Negative AOI are formally allowed in the Measurement Editor (they are imported as negative from Agilent Cary measurement data files, for example). Internally, however, these values are converted to positive, as the direction of incident light is irrelevant for the models being considered.
10. Bug fixing:
- Inconsistency of phase plotting when phase limits are 0 - 360° are fixed: in some cases the resulting phase was plotted as a constant; now, it can be plotted correctly only with Y-Axis auto scale settings.
- Computational problem fixed: it happened when stacks used with inhomogeneous materials.11.
11. RefractiveIndex.INFO import uses now the updated database (latest status, August 2024).
24.38
1. Significant progress has been made in multi-scan import and batch processing. Measurements that include multiple scans or positions are now organized as objects, allowing for flexible editing and loading:
- This feature enables the import of multi-scan measurements and saves them as individual objects. This allows multiple BBM measurements to be stored within the same project without intermingling. It is possible to switch between Multi-scan edit and edit of separate measurements.
- Multi-scan files with Meta-tags of Position type is now supported. It is possible to activate any of the available positions and to bring it to the Model processing of RE mode. This feature is especially valuable for large-area depositions and batch processing.
- The Multi-Scan import option has been extended to support the Agilent Cary measurement data files, which include Position-type measurements. OTF Studio automatically recognizes the positions associated with the measurements, making this feature particularly useful for reverse engineering and the characterization of large-area coatings in batch processing.
- Multi-scan mode in all types of supported spectrophotometers selects all available items by default.
2. Progress in characterization algorithms and features:
- Higher order inhomogneities added to the CH Model Builder.

- Empty "Preview" panel appeared when switched to RE or CH mode from another mode. Fixed.
- The loaded data for a layer material was previously subject to unnecessary truncation based on the model's re(n) and im(n) limits. This truncation was inconsistent with the assumption that loaded data should be retained as is, without any modifications. The truncation has now been removed.
- OTF Studio 64 bit hanged if ellipsometry curves are evaluated for the empty environment due to uncertainty 0/0, since there is no reflected light in such configuration. Fixed.
- A very subtle and rare bug revealed and fixed. At some laptops, 64 bit version raised a GDI+ exception during startup.
24.35

- Complimentary target color characteristics are displayed better: "1 - " prefix added to indicate computed values.
- Saving the selected tabs in all color-related panels between OTF Studio sessions: When you save the project and close the program, the configuration of opened tabs is also saved. Upon reopening the same project, the tabs will be restored to their state at the time of closing.

23.82
1. Bug in Optimization with groups fixed.
2. Corrected the format of angles in the legend and in the "Copy Numbers" option to increase the number of digits.
3. Electric field analysis options is developed (View ribbon). It is possible to change all settings using right panel and to adjust the ranges and the types of output. It is also possible to see E-field intensity and E-field phase, s- and p- polarization.
4. Export to Report of large values (GDD, for example) sometimes created overlapped numbers in the output. Fixed.
5. Ability to configure the tabular representation in Report outputs (Model menu at the Results ribbon). It is also possible to specify Measurement wavelength grid as the grid for the dispersion output.
23.79
1. Compare designs feature (View Ribbon) added. Now, it is possible to compare spectral characteristics of the designs from the design table as well as the designs from History and Collection panels.
2. Horizontal scroll bar added to Target/Measurement editors.
3. A computational degradation of performance in cases when some materials were using Spline interpolation fixed.
4. Better visual feedback in the Layer Model Builder: disabled parts of the model are now shown in gray color.
5. Corrected Layer Model Builder problem: when no models are active, in some cases the discrepancy is increased after Fit action.
6. It was possible to select 1 or even 0 materials from multi-start optimization. Fixed. At least 2 materials should be selected for multi-start correct operations.
7. In some cases merit function (MF) was displayed as "n/a" in the main status bar, even if some valid targets were loaded. Fixed.
8. In some cases, after gradual evolution it was not possible to select constraints for some materials, especially when they were excluded/included to Active list. Fixed.
9. Added check for at least 2 materials before gradual evolution starts.
10. If design is edited without layer materials in the memory, it creates Access Violation errors. Fixed.
11. Copy Numbers added to OM plots.
12. MOCCA export adjusted to conform better MOCCA specifications (rate, fixed layers attributes - "non-optical-control").
13. The caption of "New Item Name" form is also updates in accordance of database type selected in this dialog.
23.77
1. Fixed a bug in the Substrate characterization. This bug significantly decreased the efficiency of non-parametric model.
2. In rare cases, Access violation problems were possible, if Monte Carlo computations were running, and the Monte Carlo panel is closed. Fixed.
3. Import of Agilent measurements improved: now it is possible to import traces one by one without closing Import dialog.
4. Added import of designs from Essential Macleod files.
23.76
1. Tooltips feature added to the Evaluation plots.
2. Added SVG and EMF export format to the list of "Save Chart" command (Results ribbon).
3. Copy Numbers feature added: it is available at the right-click drop-down menu of Evaluation and Fitting plots.
4. Several display bugs in OM mode fixed: non scaled data in the plots were used.
5. Tooltips format (the number of digits) is dependent now on the selected units, argument values are also shown.
23.75
1. Added Color Rendering Index to Color values.
2. Fixed scaling problem in Integral Target part of the merit function.
3. Sensitivity analysis feature added.
4. Problem with positions of secondary dialogs at multi-monitor systems fixed.
