原子力显微镜与SNOM、拉曼、共聚焦显微镜联用一体机

Raman spectroscopy,confocal microscopy and SPM for interdisciplinary science at the molecular level

Integration:The key to the new sciences

Change happens at interfaces and today’s most exciting changes in microscopy are happening where multiple technologies interface. NTEGRA Spectra is a prima example, uniting the full power of confocal microscopy, scanning probe microscopy, and Raman spectroscopy in one platform.

1.AFM probe and laser beam are perfectly coordinated with each other. The AFM probe can be placed within the laser spot with nanometer precision—as it is necessary for tip-enhanced optical effects. Movement in 6 different axes is controlled by closed-loop sensors.

2.High NA objective is rigidly integrated into the SPM base. It provides unprecedented optical system stability—designed for long-term and weak-signal experiments.

3.Reflected laser light is used to obtain confocal laser image.

4. TE-cooled(-70 degree centigrade) CCD serves as a sensitive spectroscopy detector.

5. Alternatively avalanche photodiode can be used for photon counting.

6. Flexible polarization optics in both excitation and detection channels. User defined optical filters.

7. Excellent software integration has been realized. All system modules(AFM, optics and mechanics) are driven by the same software package. Lasers, gratings, pinholes, etc, can be chosen and adjusted from the program.

8. NT-MDT provides solutions for all possible TERS geometries
