Spekwin32 is a multiformat spectra viewer & processor for UV-VIS, IR, Raman, fluorescence. One of Spekwin32's main goals is the consistent display of spectra coming from different sources. At the moment, 16 different spectral file types from commercially available spectrometer systems can be read. Spekwin32 is able to handle UV/VIS, fluorescence, NIR, IR and Raman spectra while the main focus is on UV/VIS and fluorescence.

This software allows to do many tasks on spectra that come across in the laboratory everyday life (baseline correction, spike removal, normalization, smoothing, averaging, integration, finding peaks, calculation of concentration, absorption coefficient and oscillatory strength, ...).

As important features for fluorescence spectroscopy there are: calculation of degree of polarization, Center of gravity, fluorescence quantum yield; correction of excitation intensity of fluorescence spectra, calculation of excitation spectra from two-dimensional fluorescence spectra, Displaying two-dimensional fluorescence spectra (EEM) from fluorescence or excitation spectra.

To simulate absorption spectra, there is an algorithm that allows to fit any group of curves (Gauss type) to present spectra.

For simple documentation, any number of spectra can be saved together as prorietary Spekwin32 binary file or as two sorts of human readable ASCII files (*.dat and *.csv). Spectral data can also be exported into two commonly accepted spectra file formats: JCAMP-DX and THERMO Galactic/GRAMS spc files. The current plot can be printed, copied to the clipboard or saved as graphics (WMF, GIF, TIFF, BMP, PNG). For LaTeX freaks, Gnuplot parameter files and data files can be created that allow to produce EPS files directly.

Spekwin32 Features:
1. Fast scaling, zooming, rescaling with mouse
2. Status bar at bottom displays current mouse position => fast reading of data points
3. X-axis as wavelength, wavenumbers or electron volts, complementary second x-axis possible
4. Y-axis as transmittance, absorbance, molar absorption coefficient and log(absorption coefficient)
5. Automatic choice of axis types on reading spectral data files
6. Free axis caption, font, font size
7. Grid mode
8. Spectra display with arbitrary colour, line type, line width
9. Display of two-dimensional fluorescence spectra (EEM)
10. Drag&Drop for Spekwin32-readable files
