Abstract
A microspectroscopic device includes: a wavelength-tunable first light source configured to emit pump-light in a mid-infrared wavelength range; a second light source configured to emit probe-light in a visible range; a light source controller configured to change a wavelength of the infrared light source; a first optical system configured to combine the pump-light and the probe-light to acquired combined light and concentrate the combined light on a minute part of a sample; a second optical system configured to block at least the probe-light from transmitted light or reflected light of the sample; a detector configured to detect light incident thereon from the second optical system; a first spectrum acquisition means configured to acquire a spectrum of the incident light during the probe-light emission to the sample as a Raman spectrum or a fluorescence spectrum of the sample; and a second spectrum acquisition means configured to acquire an infrared absorption spectrum of the sample, based on a change in the spectrum of the incident light with respect to a change in a wavelength by the light source controller during the probe-light and pump-light emission to the sample.
