Abstract
【解決手段】
筒35,36などを設けることにより付属装置の光学系を収容している空間を密閉して、測定光が通る空間と、外の雰囲気とを遮蔽し、測定光が通る空間内に除湿機38を設ける。除湿機を狭い空間に配置することで、光の通る空間を効率よく、短時間で除湿し、内部の湿度を下げることができるので、光路上で受けてしまう水蒸気の吸収を減らすことができる。水分による測定データへの悪影響を防ぐことができ、除湿のための待ち時間を短くすることもできる。
【選択図】 図2
Description
雰囲気中に含まれる水蒸気の量が多いときは、水蒸気の吸収波長領域のエネルギーが小さくなるために特に影響を受けやすく、ノイズが出やすくなる。
