OptLab-SPX Software for the determination of color data and optical
material parameters
OptLab-SPX is a software for the determination of a variety sample parameters calculated from the sample spectrum. This can be the color of a transparent or opaque material, the blocking characteristics of protective glasses, the whiteness index of a dye or the sunlight transfer capability of window glass.

OptLab-SPX main window
OptLab-SPX is compatible to most Thermo Scientific UV/Vis and Vis spectrometers and can be used as an additional module to the Thermo Scientific VISIONlite™ applications software for UV/Vis spectroscopy.
OptLab-SPX is also compatible to PerkinElmer UV/Vis spectrometers Lambda 2/2S, 11/12/14, 10/20/40 and 25/35/45.
As an off line package OptLab-SPX is able to import VISIONlite spectra, JCAMP spectra, UVWinLab
2.0-3.0 and 5.0 or higher ASCII spectra and ASCII data tables including MS Excel™ csv tables.
OptLab-SPX records the required transmittance or reflectance sample spectrum and performs any
required number of calculations. These can either be done automatically after spectrum recording or can be done off line with stored spectra. Generally the discussed calculations are derived from
national and international norms and standards like DIN, ISO, ANSI, JIST, etc.:
- UV-, NIR- and light transmittance coefficients acc. EN, ANSI, JIST etc.,
- XYZ, XYy and Lab color values for different observers and illuminants acc. CIE/DIN/ASTM,
- CIE color difference calculations
- Color inspection acc. European Pharmacopeia
- Pt-Co/Apha/Hazen color values,
- Gardner color values
- Iodine color values
- Whiteness and yellowness index acc. ASTM,
- Coefficients for signal recognition acc. DIN (Q-factor) and British Rail,
- UV- and NIR-protection coefficients,
- Solar protection factor acc. COLIPA and AS/NZS,
- Average spectrometric values and single values at specific wavelengths,
- Check against high/low data and high/low reference spectra.
A complete list of the OptLab-SPX parameters is given on the next page.
Calculation parameters are summarized as an OptLab-SPX method. The method determines the type of calculations, details of result output (like automatic printout or graph scaling) and the type of sample thickness transformation. An unlimited number of methods can be stored under selected names for easy usage in a routine environment.
Sample Thickness Transformation
To characterize transparent materials it may become necessary to generate results for a standard
sample thickness. The sample thickness recalculation of an actual sample spectrum can be based on a single reflectance value, or on the material refractive index or on a full single-surface reflectance spectrum.
Color Inspection according to EP
One of the special features of OptLab-SPX is the option to perform color determinations according to the European Pharmacopeia. The procedure described in the EP has been transformed to an
objective principle, which does no longer require the mixing and the measurement of reference solutions.
Configuring OptLab-SPX
Users can modify the list of available calculations; other calculations can be added, based on the
available algorithms. It is also possible to change the naming of the predefined calculations.
Report Configuration with Reporter-SPX
The additional installation of the ascanis Reporter-SPX Software allows to configure the report in
many aspects, for example to define the spectrum diagram in size, color and appearance or to add additional texts and company logo.
OptLab-SPX system requirements: MS Windows 95® or MS Windows NT 4.0/2000/XP®
