AIST Software PeakLab

PeakLab’s fitting of spectroscopic peaks is unsurpassed for accuracy and ease of use. From a true Voigt function with a full precision only matched by Mathematica, to modeling Gaussian, Lorentzian, and Voigt models with asymmetric instrument response functions as seen in XPS and Raman spectra, to fitting the full theoretical shapes in Gamma Ray spectra, PeakLab will easily manage every difficult spectral modeling problem. PeakLab uses a number of new patentable peak fitting algorithmic innovations to effortlessly get you the correct solution, an important consideration in any iterative nonlinear optimization.
