This multiformat spectroscopy software supports UV-VIS, NIR, IR, Raman, fluorescence analyses. It enables quick viewing and processing of various spectrum formats from multiple devices, including JCAMP-DX, Thermo GRAMS, Varian Cary 50, and others.

The software is designed to display and process multiple spectra simultaneously, which can be exported as ASCII, csv, Thermo Galactic/ GRAMS SPC, JCAMP-DX or binary data, as well as graphics files such as WMF, GIF, PNG, TIFF, and BMP. Spekwin32 also offers batch export into three file formats (spc, dx, csv), making exporting large data sets quick and easy. The software additionally allows for parameter calculation and manipulation of absorption and fluorescence spectra, including extinction coefficients and fluorescence quantum yields.
Spekwin32 is free for non-commercial, academic, educational, and non-profit use. However, commercial users will need to pay a one-time licence fee. The software comes with comprehensive support and can be downloaded from the Spekwin32 website. Overall, Spekwin32 is a great option for optical spectroscopy data analysis, offering versatile features and support for multiple data formats.
