Spectral acquisition time is user selectable over a wide range. Low‐resolution spectra may be taken rapidly (about 30s/scan) or very slow scans with long time exponential averaging may be chosen. Data are obtained using a two‐phase lock‐in in magnitude mode so that no phasing of the lock‐in amplifier is required. The advantages of this system are discussed and some representative data presented.K. W. Hipps. (1987).
