Integration of SPM and confocal microscopy/Raman scattering spectroscopy. Owing to Tip Enhances Raman Scattering it allows carrying out spectroscopy/microscopy with up to 10 nm resolution.

NTEGRA Spectra - AFM / CONFOCAL RAMAN & FLUORESCENCE / SNOM / TERS

Integration: The key to the new sciences
Change happens at interfaces and today’s most exciting changes in microscopy are happening where multiple technologies are interfaced together. NTEGRA Spectra is a prime example, uniting the full power of atomic force microscopy (AFM), confocal Raman and fluorescence microscopy and scanning near-field optical microscopy (SNOM) in one platform. more info

Spectroscopy
Scanning Near Field Optical Microscopy (SNOM)
Optimized for Tip Enhanced Raman Scattering (TERS) and other tip-related optical techniques
(S-SNOM, SNIM, TEFS, STM-LE etc.)
 
Confocal Raman/Fluorescence microscopy
Confocal Raman/Fluorescence/Rayleigh imaging runs simultaneously with AFM (during one sample scan)
Diffraction limited spatial resolution: <200 nm in XY, <500 nm in Z (with immersion objective)
True confocality; push button from software to control the motorized confocal pinhole for optimal signal and confocality
Motorized variable beam expander/collimator: adjusts diameter and collimation of the laser beam individually for each laser and each objective used
Full 3D (XYZ) confocal imaging with powerful image analysis
Hyperspectral imaging (recording complete Raman spectrum in every point of 1D, 2D or 3D confocal scan) with further software analysis
Optical lithography (vector, raster)
AFM/STM: Integration with spectroscopy
Upright and Inverted optical AFM configurations (optimized for opaque and transparent samples correspondingly);
side illumination option
Highest possible resolution (numerical aperture) optics is used simultaneously with AFM: 0.7 NA for Upright, 1.3–1.4 NA for Inverted
AFM/STM and confocal Raman/Fluorescence images are obtained simultaneously (during one scan)
All standard SPM imaging modes are supported (>30 modes) — combined with confocal Raman/Fluorescence
Low noise AFM/STM (atomic resolution)
Vibrations and thermal drifts originating from optical microscope body are minimized due to special design of optical AFM heads
Focus track feature: sample always stays in focus due to AFM Z-feedback; high quality confocal images of very rough or inclined samples can be obtained
