Cavity Enhanced Raman Spectroscopy
Challenge :
Raman signals can be enhanced by placing a sample in a microcavity . In order to acquire high-resolution Raman images , ultra accurate positioning of the microcavity is necessary . Each Raman spectrum is contributing to the final step-scanned image . Therefore , the microcavity has to be moved with nanometer sized steps .
attocube ´ s solution :
Benefits :
• accurate movement on different scales : millimeter – micrometer – nanometer
• coarse & fine movement
• step size in the nm-range attocube nanopositioners combine movements over millimeters with nanometer accuracy . Typical samples are of the millimeter size . Hence it is possible to navigate and find a micrometer sized region of interest , perform there step scans with nanometer step size , and thus create high-resolution images .
