Environmental sensor which can detect and identify environmental pollution in real time is needed. It could be made by using Multiple internal reflection FTIR(MIR-FTIR) because of its short measurement time and high sensitivity. We chose GaAs which transmits large band lights which many molecule vibration exist in. It is possible to identify the gas which exists in the atmosphere around the crystal by FTIR spectrums. It is also possible to measure concentration of the gas in the atmosphere by measuring peak intensity of it. The result of reproducibility experiment will be reported finally.
