Abstract
An optical probe consists of a first component made of a first optical material having a light transmission property in the far ultraviolet region, and a second component made of a second optical material arranged in contact with the surface of the first component. For example, the second optical material has a higher refractive index in the far ultraviolet region than the first optical material. The second component is provided, on a side in contact with a sample, with a surface totally reflecting light having incident angle equal to or larger than the critical angle. Alternatively, an optical probe has an optical material having a light transmission property in the far ultraviolet region, having a surface totally reflecting a ray of light of incident angle equal to or larger than the critical angle, at a side in contact with a sample, and the refractive index is higher near the surface than at the other parts in the far ultraviolet region. Consequently, a spectroscopic measurement becomes possible on very small solute components dissolved into water or the like in the far ultraviolet region.
