BAC101 Industrial-Grade Raman Probe The BAC101 is an immersion Raman probe designed for in-situ analysis including those in demanding industrial environments.

The BAC101 industrial-grade probe is available with shafts of 316SS

or Hastelloy C-276, offering a wide range of operating temperatures and chemical compatibility. They are offered for use with our 532

and 785nm excitation portable Raman instruments, and high-throughput (HT) versions are available for optimal performance with the i-Raman Prime series high-throughput instruments. Due to the extremely short working distance of the probe shaft, highly Raman Accessory

reproducible results are achieved working with the probe tip immersed in liquids, slurries, powders, or in direct contact with solids.

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 C-276 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 standard fiber comes at a length of 1.5m and includes flexible fiber coupling, internal support and a durable protective PVC jacket. The excitation fiber has a 105 μm core diameter and is FC/PC terminated. The collection fibers for the HT models have a 300 μm core collection fiber and are FC/PC terminated, while standard models have a 200 μm core and are SMA 905 terminated.

For unpressurized measurements requiring longer working distances, such as going through glass reactors, Kalrez O-ring sealed shafts RIS100-FS (fused silica window) and RIS100-SA (sapphire window) are available.
