拉曼探针
Raman probes are specifically developed for coupling with HES spectrometers for Raman observations.
标准和僵持的拉曼探针
When the size of a sample seems to be large, in a risky or high-temperature setting, or for any reason, it is hard to bring to a spectrometer, a probe offers the perfect solution for obtaining real-time observations.
As far as Raman spectrometers are concerned, a Raman probe is utilized to quantify the inelastic scattering of light observed from a sample. Raman scattering is generated when the energy levels of photons are shifted up or down due to excitation by a monochromatic source (generally a laser).
振动频率的变化用于识别靶物质的组成。拉曼探针将激光浓缩在样品上，收集散射的光，然后将其馈回光谱仪。
The Raman probes are perfectly suited for coupling with IS-Instruments’ range of high etendue HES spectrometers. The company now provides two probes: the Standard Raman Probe developed for close or contact measurements, or the Stand-Off Raman Probe with the ability to make measurements from a distance of up to 3 m.

The fiber-coupled RP1000 Raman probe has been developed to work with the HES2000 spatial heterodyne Raman spectrometer. The probe functions at a 1000 mm stand-off distance from the 100 mm diameter window, thus enabling non-destructive investigation of target samples to arrest material-specific Raman spectra.

RP1000 Raman Probe for Stand-Off Measurements
IS-Instruments’ Stand-Off Raman probe has the potential to make measurements ranging from distances of up to 3 m from the target. The Stand-Off Raman Probes are equipped with the highest quality optical filters to inhibit any undesirable laser and have focal lengths ranging from 50 mm up to 3 m.
这些探针已经开发出具有具有匹配特性的HES光谱仪的ISI范围，并旨在减少不良的背景光。这使得最佳的光收集即使在距离处。
The company’s Stand-Off Raman probe can be attached to a robotic arm for deployment by ROV, which is perfect for remote sensing in dangerous settings. The Raman probe is at present being utilized in the nuclear decommissioning sector to eliminate the human element from the detection of substances in gloveboxes.
