Abstract

PURPOSE:To detect without fail the absorption caused by a sample with any wavelength in a wide range from an ultrared region through a visible range, by securing such constitution in which the continuous spectrum beam radiated from a light source is irradiated to a photo-acoustic cell via a beam chopper means. CONSTITUTION:The white beam of a continuous spectrum which is radiated from a xenon lamp 2 is separated by a diffraction grating 6 via a lens 3, a slit 4 and a mirror 5. Then the spectra having the wavelengths of 230mm. among the separated ones are cut by a shielding plate 7, and others are condensed again by a condenser lens 8. These spectrum beams are made incident to an optical sound cell 10 while being intermitted by a beam chopper means 9. The signal proportional to the light absorption quantity of a sample is obtained from a piezo-resistance effect element 11 of the cell 10 by a photo-acoustic effect to be recorded by a recorder 13 via a lock-in amplifier 12.
