IS-Instruments has developed a prototype Raman probe designed to measure samples through windows and other optical mediums that would typically obscure spectroscopic measurements.
The probe uses a biaxial design to minimise unwanted background signal and uses suction cups to securely mount the system.
Development started for this as part of an Innovate project looking at developing freeze-drying technology for pharmaceuticals and medicines. Various spectroscopic techniques were added into a freeze-dryer to allow freeze-drying runs to be monitored and measured over time. This prototype through-window Raman probe uses these same ideas but is intended to be easily retrofitted to existing freeze-dryers using the suction cup mounting design.
The high throughput of our HES2000 spectrometer makes it well suited to stand-off measurements, and this probe design leverages this to measure samples through obscuring optical mediums like thick acrylic or thick glass windows, which traditional Czerny-Turner based Raman spectrometers often struggle to do.
