PHOTOTHERMAL CONVERSION SPECTROSCOPIC ANALYSIS METHOD, AND PHOTOTHERMAL CONVERSION SPECTROSCOPIC ANALYSIS SYSTEM FOR EXECUTING THAT METHOD

摘要

A photothermal conversion spectroscopic analysis method in which high sensitivity measurement can be carried out, and a photothermal conversion spectroscopic analysis system executing that method. The photothermal conversion spectroscopic analysis system comprises a chopper (112) disposed in the vicinity of a pumping light source (111) on the optical path of pumping light emitted from the pumping light source (111), a mirror (114) for deflecting the advancing direction of pumping light, a dichroic mirror (113) for making the pumping light coaxial with detecting light input from a detecting light source (120), a lens (10) having an appropriate chromatic aberration, and a holder (15) for holding the lens (10) adjustably in three axes.
