The IRTracer-100’s interferometer is optimized and stabilized using a combination of a smooth moving mirror system and the Advanced
Dynamic Alignment. To assure that the IRTracer-100 is always in the optimum operating condition, a self diagnoses routine monitors
the operation of the system at initialization and constantly during operation In addition, standard EP/CHP/JP/USP/ASTM validation
programs are provided to evaluate the FTIR performance.
