描述了可见光到红外差频转换器的漂移补偿和扫描校准技术，能够以 5 × 10−4 cm−1 的精度和再现性记录高分辨率分子光谱。通过在低压、多普勒限制和大气压、碰撞扩大条件下扫描甲烷 ν3 能带中的四面体精细结构，说明了光谱仪的功能。
Techniques are described for drift compensation and scan calibration of a visible-to-infrared difference-frequency converter enabling high-resolution molecular spectra to be recorded with a precision and reproducibility of 5 × 10−4 cm−1. The capabilities of the spectrometer are illustrated by scans of the tetrahedral fine structure in the ν3 band of methane under low pressure, Doppler-limited and atmospheric pressure, collision-broadened conditions.
