Development of an In-House Grating Spectrometer System for Validating Acousto-Optic Tunable Filter Spectrometer Results

Abstract : We describe the design of a grating spectrometer system. We obtained emission spectroscopy results of a lamp source from a visible to near infrared (vis-NIR) acousto-optic tunable filter (AOTF) spectrometer and from an IN-house developed Grating (ING) spectrometer. We compare the measured lamp source emission-spectra results from the grating spectrometer with results obtained with the AOTF spectrometer and results from the lamp manufacturer. The grating spectrometer compares well with the manufacturer's calibrated data and results obtained from the AOTF spectrometer.
