Abstract

High-power special-shaped infrared radiation sources are usually used for detection systems such as compact photoacoustic spectrometers for gas detection. In this article, the light emitting characteristics of a rod-shaped infrared thermal radiation light source was obtained experimentally. Then, based on the luminous characteristics and the illuminance requirements on the target photoacoustic cell, combined with the basic principle of conservation of light energy during transmission, the shaping system for the special-shaped infrared radiation source for photoacoustic spectroscopy was designed and optimized, aiming to achieve efficient collection and utilization of light source beams.
