IntelliCal-Automated wavelength and intensity calibration routines significantly improve accuracy of recorded spectra

Calibration of dispersive spectral instruments has long been problematic for researchers. When a spectrum is plotted along a pair of axes, the x-axis usually represents wavelength or wavenumbers, while the y-axis represents intensity. Optical spectroscopic equipment manufacturers have all but left the task of determining…Read Full Article

Fully automated wavelength calibration method optimizes data accuracy

The recent launch of Princeton Instruments’ powerful LightField® 64-bit data acquisition software also heralded the arrival of a brand new, fully automated wavelength calibration method developed to achieve unprecedented accuracy for spectroscopy applications (see Figures 1–4). Currently offered as a LightField package option, patent-pending IntelliCal® technology from Princeton Instruments enables…Read Full Article
