| Abstract: | Based on the analysis of the disadvantages of general optical path based on the reflectance accessory,this article designed a simple and useful double-optical path to improve the infrared spectroscopic measurements.The new optical path technique can record synchronously the spectroscopic signals of sample and background,reduce the experimental errors,and correspondingly increase the sensitivity.Moreover,it can be applied to both the experiments under small incident angles and large angles conveniently. |
| Keywords: | infrared spectrometer transmittance and reflectance double-optical path |
