ABSTRACT:
It is an object to provide a photothermal conversion spectroscopic analysis method that enables measurement to be carried out with high sensitivity, and a photothermal conversion spectroscopic analysis apparatus that carries out the method. The photothermal conversion spectroscopic analysis apparatus is comprised of an exciting light source111, a chopper112that is disposed close to the exciting light source111in the optical path of exciting light emitted from the exciting light source111, a mirror114that changes the direction of travel of the exciting light, a detecting light source120, a dichroic mirror113that has detecting light from the detecting light source120incident thereon and makes the exciting light and the detecting light coaxial, a lens10that has a suitable amount of chromatic aberration, and a holder15that holds the lens10such as to enable adjustment along three axes.
