Abstract: A Raman infrared compound microscope device includes: a first light source that generates laser light; a second light source that generates infrared light; a third light source that generates visible light; and a first optical system. The first optical system orients the visible light having reached the first optical system in different directions between when performing a Raman analysis using Raman light generated from a sample by irradiation of the laser light and when performing a first infrared analysis using the infrared light having passed through the sample.

Abstract: A camera captures a surface image of a sample. A reference position setting processing unit changes the focal position of the laser light with respect to the sample on a stage to set the focal position at which a spot area of the laser light on the surface image meets a predetermined first criterion as a reference position. A determination processing unit determines whether or not the light quantity incident on the slit provided in front of the detector meets a predetermined second criterion based on the change in the spot position of the laser light on the surface image by changing the focal position in the depth direction with respect to the reference position. An angle adjustment processing unit adjusts the angle of the mirror when it is determined that the light quantity incident on the slit does not meet the predetermined second criterion.

Abstract: An infrared Raman device is capable of switching and performing Raman measurement and first infrared measurement on a sample. The infrared Raman device includes an objective lens for Raman measurement; a first observation lens for infrared measurement; a laser light source that generates laser light; a first infrared light source that generates first infrared light; and a mirror. The mirror is disposed at time of the Raman measurement to reflect the laser light to cause the laser light to pass through the objective lens for Raman measurement and reflect Raman light generated from the sample by the laser light that passes through the objective lens for Raman measurement and radiated to the sample. The Raman light passes back through the objective lens for Raman measurement.
