The BAC101 industrial-grade probe is available in two standard designs that offer different operating temperature ranges and chemical compatibility. They are offered for use with our 532 and 785 nm excitation portable Raman instruments. The BAC101-SS-532 (785) model comes with a 316 stainless steel probe shaft, with a high-precision UV-grade sapphire lens affixed to the end of the shaft using a proprietary epoxy designed for chemical resistance and high temperatures. The BAC101-HS-532 (785) model has a high-performance Hastelloy C276 shaft, with the sapphire optics affixed to the Hastelloy using gold-based compression sealing, providing an even wider temperature range with exceptional chemical resistance for more demanding environments. The extremely short working distance of these two designs means the probe tip can be immersed in liquids, slurries, powders, or directly contact solids, yielding highly reproducible results.
For unpressurized measurements requiring longer working distances, such as going through glass containers, two additional Kalrez O-ring sealed shafts, RIS100-FS (fused silica window) and RIS100-SA (sapphire window) can be used in place of the SS or HS type shafts.
