Acquisition of Vertex 70V FTIR System for Ultra-Broad Range Infrared Spectroscopy
Abstract
Optical spectroscopy is a cornerstone characterization method for IR optoelectronic materials and devices. Development of devices operated in the long-wave infrared (LWIR) spectral range requires spectroscopic tools of ultimate accuracy and precision due to lower bandgap energy and fundamentally lower rate of radiative recombination. Vertex 70v vacuum Fourier-transform infrared spectrometer will address this call combining highest sensitivity and ultra-broad spectral range. Evacuated optical bench allows elimination of parasitic optical absorption of atmospheric gases and water vapor thus providing for highest sensitivity and spectral clarity. Step-scan option enables time-resolved and modulation spectroscopy experiments. Vertex 70v FTIR system will be a key equipment component for the experiments, directly related to all the ongoing research projects of the Optoelectronic group: The acquired system includes ¥ Infrared vacuum spectrometer Vertex 70v with the resolution of 0.4 cm-1 and scan rate of 20 spectra/sec at 8cm-1 resolution. ¥ External measurement channels, which will make possible measuring luminescence spectra in the far-infrared and terahertz spectral range. ¥ Spectral Range Extension, which extent the operation spectral range to 50-8000cm-1 ¥ Step-Scan Option will enable measuring pulse signals with low duty cycles ¥ Silicon composite bolometer will provide ultimate sensitivity in the spectral range 50-650cm-1. ¥ Powerful software package for the data analysis.
