Accuracy? Resolution? How did you calibrate it?I bought a Thunder Optics spectrometer from France awhile ago.
Using this software:
Spectragryph - optical spectroscopy software
SpectraGryph: Open all sorts of spectra. Process & analyze them with ease. Rock solid. Lean. Easy to use. For UV/VIS, NIR, FTIR, Raman, fluorescence spectra.www.effemm2.de
It was adequate for my purposes.
