ABSTRACT:
A mid-infrared spectroscopic probe attached to a fiber-optic cable comprises an optically transparent, heat-insulating crystal which is placed between the ATR crystal and the end of the fiber-optic cable so as to provide optical coupling from the cable to the ATR crystal while protecting the fiber-optic assembly inside the cable from excessive heat when the probe is used in high-temperature sample streams. The ATR crystal is tapered outwards towards the sampling end to ensure that pressure from the sample stream, e.g., in a plastics extruder, does not displace the crystal, but rather forces it into tighter contact with the seal in the probe head.
