GAS CELL INCLUDING CURVED MIRROR AND FOURIER TRANSFORM INFRARED SPECTROSCOPY USING SAME

摘要

Disclosed are a gas cell, including a curved mirror, and a Fourier transform infrared spectroscopy using the same. The gas cell, including a curved mirror, includes: a first optical path changing part changing an optical path of incident light; an optical path extending part extending the changed optical path of the incident light to increase contact with internal gas; and a second optical path changing part changing an optical path of emitted light emitted from the optical path extending part. Therefore, as the frequency of contact with gas is increased due to the extension of the optical path of the incident light, the spectrum distribution of the emitted light and incident light is precisely detected, and more specifically, even when the concentration of the gas is low, the spectrum distribution of the emitted light and incident light is able to be precisely detected.;COPYRIGHT KIPO 2016
