BAC102 Raman Trigger Probe The BAC102 Raman Trigger Probe offers a trigger function which is designed for versatility in making Raman measurements. The probe can be brought directly to the sample and make contact with either the sample or the packaging of the sample via a detachable distance regulator that ensures proper focusing while minimizing contamination to the lens material. The trigger button provides the convenience of initiating measurement from the probe head.

Different versions of the probe with varying optical lenses allow for Raman Accessory

measurements down to 65cm-1 Raman shift (100 cm-1 for 1064 nm version).

The standard fiber length of 1.5m includes flexible fiber coupling, internal support and durable protective PVC jacket. The excitation fiber has a 105

μm core diameter and is FC/PC terminated. The collection fibers for the high throughput models (HT) 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.

The standard shaft is 304SS with a flat quartz window and spot size of 85 μm. Custom probes can be constructed with dimensions, material and working distance to suit your application needs. For unpressurized immersion measurements, Kalrez O-ring sealed shafts RIS100-FS (fused silica window) and RIS100-SA (sapphire window) are available.

Notes:

1) Working distance is defined as the distance from the focal point in air to the end surface of the shaft.

2 ) The probe body and shaft are not sealed. To prevent irreversible damage caused by condensation on internal optic surfaces, do not subject any part of the probe to a temperature below the dew point.

If needed, use a purged probe.
