VERTEX 70 series offer unmatched performance and versatility for demanding analytical and research applications in Fourier Transform Infrared Spectroscopy FTIR. Its innovative design results in the highest flexibility and highest performance. The data acquisition is based on two channel delta sigma ADCs with 24-bit dynamic range, which are running in parallel and integrated into the detector pre-amplifier electronics. This advanced DigiTect technology prevents external signal disturbance and guarantees the highest signal-to-noise ratio. The new VERTEX FM functionality provides the unique possibility to acquire a complete far and mid IR spectrum from 6000 cm-1 to 80 cm-1 (or to 50 cm-1 with the VERTEX 70v vacuum optics bench) in a single step measurement.
