Fiber probes: High Efficiency Raman sensors
The SuperHead is a high efficiency remote Raman probe which enables in situ non-invasive chemical analysis to be undertaken. The purpose of the SuperHead is to efficiently deliver the laser beam to the sample material, and to collect and filter the returning Raman signal.
The SuperHead uses a single FC/PC terminated fiber for delivering the laser excitation and another FC/PC terminated fiber for signal collection. High efficiency filters incorporated within the probe provide effective laser and Raman filtering.
The SuperHead can perform measurements in a non-contact/non-invasive mode or in an immersion mode, using specific accessories.
Specifications:
- Compact design
- Integrated colour video camera for sample and laser spot viewing
- Confocal optics for optimised depth resolution
- Immersion and stand off probes
- High pressure/temperature probes
- Manufactured from chemically resistant materials (e.g., Hastelloy) for use in aggressive environments
Maintenance and replacement:
- Dust and contamination on the optical surfaces can significantly reduce the quality of Raman spectra. Avoid touching the optical surfaces with your fingers.
- Regularly inspect the fiber optic connectors for any signs of dirt or damage.
- The laser exit aperture on the SuperHead should be kept clean and free from debris. Dust on the laser aperture can scatter the laser light, reducing the focus on the sample and impacting the Raman signal.
- Avoid Mechanical Stress: Handle the SuperHead with care to avoid mechanical shocks that could misalign the internal optics or damage the fiber optic cables.
- Environmental Considerations: Store the SuperHead in a clean, dry environment when not in use to prevent dust or moisture from affecting its components.
