Confocal Raman Microscope Atomic Force Microscopy
WITec Alpha 300R
Characteristics
 |
|
- 532 nm laser - upgradeable
- High resolution Raman chemical mapping with a virtually unlimited number of image pixels
- Complete Raman spectra is acquired at every pixel of the image True diffraction limited optical resolution (200 nm lateral, 500 nm vertical at green excitation).
- 10x – (NA=0.24)
- 20x (AFM) – water immersion (NA=0.4)
- 50x (NA=0.75) – 100x (NA=0.9)
- The unrivaled throughput and sensitivity of the WITec instrument allows it to take up to 1300
- Raman spectra in one second with the EMCCD detector
- Two grating options (600/mm and 1800/mm):
- Spectral resolution 0.5-2.4 cm-1
- Highest throughput on the order of 70%.
- The piezo stage scans at about 2.5-100 msec/pixel/spectra with a resolution of 3-4 nm
- It is not necessary in the WITec system to translate the sample from the Raman to AFM position.
- Large samples
- Liquid samples
- Confocal in reflection mode
- Modular
- Processing software free for all users
