Spekwin32 Icon

Software for optical spectroscopy. (almost) Freeware*!

What it does
View multiple optical spectra (UV/VIS, NIR, IR, Raman, fluorescence) from different sources)

Process and analyze many spectra simultaneously

Special focus on parameter calculation and manipulation of absorption and fluorescence spectra (e. g. extinction coefficients, fluorescence quantum yields)
Supported data formats include:
ASCII | CSV | JCAMP-DX | THERMO GRAMS spc | Perkin Elmer | Jasco | Shimadzu | Avantes Avasoft | Ocean Optics | Varian Cary 50 | Agilent HP8453 | Stellarnet | Ascanis | VWR | Princeton Instruments WinSpec/WinView | Beckman Coulter DU 600/700 | Scinco Neosys | Horiba Datamax | RRUFF Raman database | and others
Export data as
ASCII, THERMO Galactic SPC, JCAMP-DX, CSV, RRUFF, or binary data

Export plots as graphics file:
