OptLab-SPX and OptLab-SPX offline  Versions

OptLab-SPX and OptLab-SPX offline 5.23  May 2015
- Control of USB connected Lambda 950 series instruments
- An additional tools directory is installed as a subdirectory of the Data directory. This directory contains a number of further calculation routines and example data that had to be copied from the CD's tools directory in former versions.
- Maximum number of calculations extended to 750 (before 500).

OptLab-SPX and OptLab-SPX offline 5.1  March 2015
- Color calculations according to ISO 11664 have been added. The calculations are done with a wavelength range of 360-830 nm and with a data interval of 1 nm. The calculations are designated "full range".
- CIEDE2000 color difference calculations have been added according to ISO 11664-6.
- Definitions for all color calculations have been changed internally: The underlying *.dat file is split into an observer and an illuminant file. Thus, it is more easy to implement other illuminants.
- The Calculations window easily allows modifying existing color difference calculations or add further color difference calculations. Accordingly, the templates "Set Color Reference .." are removed.
- If set by a specific start switch, the Calculations window also allows editing easily all other calculation types, deleting calculations or activating hidden calculations.
- A parameter definition of the optlab-spx.dta parameter definition file additionally accepts the definition of a minimal data interval of the sample spectrum. If the data interval of the sample spectrum is larger than defined, the calculation is not executed. The minimum data interval definition is added to new parameter definitions, where the underlying norm requires the setting.
- Import of csv data files is possibly also with non-ANSI formats (Unicode/UTF).
- The Result area is expanded to the left window edge, if settings are such that no parameters of the parameter area are overlaid.
- Numerical spectrum data may be introduced to calculations via the new variable "Spectrum(spectrumsetting)", e.g. Spectrum(DataInterval).
- The conditional output text in logical decisions may include text contents of the spectrum, e.g. "Spectrum(name)".
- Relevant data handling functions are automatically installed.
- A function for ordinate recalculation %R-> f(R) is added.
- With EN 410 calculations, results for ae / Te / Re are output as %-values, if a %-character is present in the format definition.
- Minor problems with Read Cursor mode cleared.

OptLab-SPX and OptLab-SPX offline 5.0  April 2014
- The parameter definition file has been reorganized. Also, a number for each parameter has been introduced, which allows to setup a parameter tree structure. Thus it is possible to insert new parameters to the parameter definition file without disturbing existing methods.
- A parallel offline version is made available that does not include instrument control. Instead a continuously updated list of measured spectra is shown.
- In offline operation (Port=None), the instruments parameters are removed. A new Spectrum selection list for offline operation allows loading easily spectra for evaluation.
- Additional switches for software startup are introduced for an external call of the software.
- The Change Application function is inserted, if the software installed with Lambda-SPX or VISIONlite.
- EN 410 calculations extended and more flexible. Intermediate spectra may be generated.
- EN 410 parameter values he, hi and lambda changed to the recommended values.
- EN 410 specific color rendering index available. The calculation also is opened to allow introducing individual test color data.
- Standard color calculation options opened so that individual illuminant and observer data can be introduced.
- A masking code can be introduced to a parameter definition so that the result line is not shown in the report.
- Multi figure result output can additionally include a line feed character.
- Additional Data Handling templates: Shift abscissa, Double GridLine, Ordinate Average, Polarizer Alignment.

OptLab-SPX 4.5 November 2013
The software has been adapted in several internal and operational aspects to the Scan application of Lambda-SPX.
- New Advanced Options window. It allows defining a start delay and repetitive scanning.
- The Advanced Options window also has additional functions to extend the Sample information window with up to 6 additional method-specific and user-defined categories for sample information. The entered information is stored with the data / result and reports. It is shown in the report and in the Spectrum information window. Positions of this information can be configured. Dedicated variables allow placing the information to a report template with Reporter-SPX.
- The Spectrum information window allows adding peak labels to the graph. The result area shows the respective peak table.
- The File menu has an additional function to load recently used spectra.
- A horizontal cursor is available.
- An additional configuration setting allows opening the File menu and the graph functions during a scan. Thus it is possible to load an additional spectrum during a scan.
- Printout can be alternatively defined in Landscape format.
- Font size of standard report sections (header, results, etc.) can be defined. Thus a line break can be avoided at times.
- The software maintains a list of up to 25 recent operators. With the Operator entry box, a drop-down list allows selecting one of them.
- The PDF storage of the Print Preview window can be configured so that it opens a File save .. window for selecting a path and entering a filename.
- During baseline correction, the live display shows the actual baseline values with TB as an ordinate mode.
- The MethodLink function is extended to allow the definition of multiple samples.
- Default attenuator spectra are installed (Lambda 950 series) to the Data directory. The user is warned, if instrument specific files are not yet established instead.
- The File / Load method function is able to load report templates for execution.
- Color difference calculations can be done against XYZ data of a reference sample.
- The XYZ calculation can optionally be extended to output the X0, Y0 and Z0 data for the selected illuminant/observer.
- Additional templates (CDs tools directory) for transforming the spectrum abscissa (nm -> cm-1, eV, THz) and the spectrum ordinate (A ->dB, mA, o.d.).
- A Show Baseline Data Handling template is available (CDs tools directory) to load the active baseline data to the graph (Lambda 950 series instruments).
