Abstract

An infrared microscope includes an illumination optical system which guides infrared red to an analysis position on a sample; a connection optical system which guides infrared light, supplied from an infrared spectrophotometer, to said illumination optical system; a visible light source unit which outputs visible light to a region including said analysis position on the sample; an image acquisition unit which inputs visible light from the region including said analysis position on the sample to a detection surface and acquires a visible light image; and a detection unit which detects infrared light from said analysis position on the sample. The connection optical system can be positionally adjusted, and said image acquisition unit is capable of acquiring an infrared light image by inputting infrared light to a detection surface.

Claims

an image acquisition unit which inputs visible light from the region including said analysis position on the sample to a detection surface and acquires a visible light image; and

a detection unit which detects infrared light from said analysis position on the sample; and

the infrared spectrophotometer, wherein

said connection optical system is configured to be positionally adjusted, and

said image acquisition unit is configured to acquire an infrared light image by inputting infrared light to a detection surface.

2. The infrared microscope system as set forth in claim 1, wherein said connection optical system comprises a first plane mirror, a second plane mirror, and an adjustment mechanism which rotationally moves said first plane mirror.

3. The infrared microscope system as set forth in claim 1, wherein said visible light source unit is a white LED.

5. The infrared microscope system as set forth in claim 1, wherein said infrared spectrophotometer comprises an infrared light source which outputs infrared light, and a Jacquinot stop arranged in front of said infrared light source.

6. The infrared microscope system as set forth in claim 1, further comprising a control unit which controls said infrared microscope and said infrared spectrophotometer, wherein said control unit controls said connection optical system based on said infrared light image.

7. The infrared microscope system as set forth in claim 5, wherein said infrared light image, that said image acquisition unit is configured to acquire, includes an image of an aperture of said Jacquinot stop.

8. The infrared microscope system as set forth in claim 1, wherein said image acquisition unit is configured to acquire an infrared light image by inputting infrared light to a detection surface of a camera of said image acquisition unit.
