摘要:
A small‐volume long‐path absorption cell has been designed for use with condensable samples. The absorption cell is temperature controlled and operates over the temperature range of −10 to 80 °C. To prevent condensation of the sample on the mirror surfaces, the mirrors are individually temperature controlled and maintained a few degrees above the ambient temperature of the absorption cell. The cell has been tested and used to measure weak absorptions in water vapor in the near infrared.
