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.

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: Provided is a compact and lightweight electric field probe which has a transmitting/receiving function whereby piezoelectric crystals can be excited through the application of an alternating current electric field thereto, and piezoelectric effect signals can be detected with sufficient sensitivity. Also provided are a control system for the same, and a piezoelectric crystal detector. The electric near-field probe is provided with a capacitor, in which the space between two metal plates that are positioned parallel to each other is filled by a conductor or air, and a series resonance circuit, which has a prescribed resonance frequency and is connected in series to an inverter that is formed by winding a conductive wire around a toroidal core.
