From Dr. Friedrich Menges Softwareentwicklung:
Software for optical spectroscopy. Easy to use, fast and reliable. Viewing optical spectra (UV/VIS, IR, NIR, Raman, fluorescence) from different sources. Supported data formats include ASCII, JCAMP-DX, THERMO Galactic GRAMS SPC, Perkin Elmer, Varian Cary 50, Scinco Neosys 2000, Bio-Rad FTS 3000 MX, Agilent/HP 8453, Avantes Avasoft, JASCO SpectraManager, Shimadzu, OceanOptics, Ascanis Lambda-SPX, Milton Roy Spectronic 3000, Roper Scientific/Princeton Instruments WinView/WinSpec, Beckman Coulter DU, THERMO Electron Helios Alpha, WTW photoLab, Horiba Datamax, RRUFF, GL Gem Raman. Displaying and batch processing many spectra simultaneously. Exporting data as ASCII, csv, Thermo Galactic/ GRAMS SPC, JCAMP-DX or binary data as well as graphics files (WMF, GIF, PNG, TIFF, BMP). Batch export into three file formats (spc, dx, csv). With a special focus on parameter calculation and manipulation of absorption and fluorescence spectra (e.g. extinction coefficients, fluorescence quantum yields).
Free for non-commercial, academic, educational, non-profit use. One-time licence fee for commercial users.
