<p>An optical probe consists of the first portion of a first optical material exhibiting light transmission characteristics in far ultraviolet region, and the second portion of a second optical material arranged in contact with the surface of the above-mentioned portion. For example, the second optical material has a higher refractive index in the far ultraviolet region than the first portion. The second portion is provided, on the side touching a sample, with a surface totally reflecting light having an incident angle of critical angle or above. Alternatively, the optical probe is composed of an optical material exhibiting light transmission characteristics in far ultraviolet region, is provided, on the side touching a sample, with a surface totally reflecting light having an incident angle of critical angle or above, and has a refractive index in the vicinity of that surface that is higher than that at other parts in the far ultraviolet region. Consequently, a trace solute component dissolved into water can be subjected to spectrometry in the far ultraviolet region.</p> |
