Long-term temporal and scanning characteristics of a double-beam diode-laser spectrometer.
A diode-laser dual-beam spectrometer using reflective optics and a special lock-in amplifier has a 100 +/- 0.25% base line flatness and a long-term base line drift of <0.25%. The system is highly immune to fringe interference occurring before the ratioing system.
