Transmission Infrared Fiber Optic Probe for Gases
Transmission infrared fiber optic probes for gases are designed to be used with any spectrometer or photometer.
The design of transmission infrared fiber optic probes is based on a bifurcated fiber bundle. In order to increase the optical path length to 10 – 40cm, the collimated beam design of double pass (or multiple passes) gas cell is needed due to low Mid IR-attenuation in gases. This design is easily realized by the mean of the collimating objective and reflecting mirror cell.
