| description | PURPOSE:To make it possible to set the distance between the surface of a sample and a spectroscope arbitrarily, by providing a beam splitter, a condenser lens, and a spectroscope optical system, and making laser light and light from a sample in parallel on the same axis between the condenser lens and the spectroscope optical system. CONSTITUTION:A beam splitter 30 makes laser light 13 to be a specified ring shape. A condenser lens 32 converges the ring shaped laser light on the surface of a sample 16 and guides light 33 emitted from the sample in the reverse direction on the same axis with respect to the ring shaped laser light 31. A spectroscope optical system 20 includes a concave mirror 34 and expandable mirror tubes 40 and 40a. The ring shaped laser 31 and the light 33 from the sample are made to be in parallel on the same axis between the condenser lens 32 and the spectroscope optical system 20. In this constitution, the light 33 from the sample is efficiently guided to a spectroscope 22 by the adjustment of the mirror tubes 40 and 40a, regardless of the length of the distance between the sample 16 and the spectroscope 22. Thus the highly accurate, general purpose device can be obtained. |
