FlexiSpec® probes from art photonics include new type of Attenuated Total Reflection (ATR-) probes designed for harsh application conditions
Fiber Optic ATR-Probes for harsh hnvironment can be used for process-spectroscopy in Near & Mid IR range to monitor reactions in-line in a broad temperature range from -100° to +250°C. They can resist to high pressures up to 200Bar and used with FTIR or any other IR-spectrometers and spectral sensors in automated process control with process-interfaces.
