MICROSCOPIC FOURIER TRANSFORM INFRARED SPECTROPHOTOMETER

摘要

PROBLEM TO BE SOLVED: To provide a microscopic Fourier transform spectrophotometer having a small and compact overall structure in which compact optical arrangement can be realized. SOLUTION: The spectrophotometer comprises an infrared light source 2 for irradiating a sample S with an infrared light IR through an interferometer 3 and analyzes the infrared light IR transmitted through the sample S or the infrared light IR transmitted through the sample S and reflected on a member 8 for holding the sample S. A concave mirror 5 is disposed on the post-stage of the interferometer 3 and a convex mirror 19 sharing the geometric focal point with the concave mirror 5 is located in the reflection light path retractively therefrom.
