Abstract
A measurement accessory with multiple transmission-reflections uses for an infrared spectrometer, laid accessory is arranged in the sample cavity of the infrared spectrometer. Said accessory includes two parallel plane mirrors (7, 8) and a sample holder fixed between the two mirrors (7, 8). Said sample holder can fix the sample piece (9) between the two plane mirrors (7, 8) and make the sample piece parallel with plane mirrors (7, 8). During measuring, the infrared ray emitted from infrared spectrometer (17) forms a certain angle incident to the space between said plane mirrors and reflects for several times between the two parallel plane mirrors (7, 8) and the sample piece (9) is measured with multiple transmission-reflections by the infrared spectrometer. Then the infrared spectrometer (20) enters into the detector of infrared spectrometer.
