IR Light Sources

For gas analysis, gas detection and gas concentration measurements an infrared (IR) light source is required. We offer two types of IR light sources. The HSL Series is a low-cost IR source which can be used for all applications where the absorption wavelenghts are shorter than 4.5 µm. For gases like CO or NO_x, a broad band IR source of the EMIRS Series should be used to generate an appropriate signal level.
