The device for measuring an optical absorption characteristic of a sample according to the present invention comprising a light source, a optical wave-guide (1) having light input surface(s) (2a) and light output surface(s) (2b) that are opposite to each other, and a light reflecting surface (3) on which a sample (4) to be measured is disposed, through which the light passes and is reflected by a total reflection on the sample (4), one or more light transmitting means arranged between the light output surface (2b) of the optical wave-guide (1) and the light input surface (2a) of the optical wave-guide (1) so that the light is again entered into the optical wave-guide (1), and a processing device which receives the light re-exited from the optical wave-guide (1) through the output surface (2b) and detects the optical absorption characteristics of the sample (4) on the basis of the light received, whereby the light which passes through the optical wave-guide (1) is conducted to the optical wave-guide (1) again, the light is again entered the optical wave-guide (1), and the light is again reflected on the sample. |
