- Aperture mode SNOM in emission mode
- Transmission (for transparent samples) and reflection
configurations are possible
- Light detection by fototube in either mode is obtained via optical
elements
- Fibers: Commercially available "Tapered" sensors with 50
nm
hole (nominal value) Typical emission is 1 nW. Sensors come
already mounted on A.P.E. Research sample holder.
- Near field laser: external source on laboratory table
- Maximum scan area: 85 mm x 85 mm
- Maximum surface area: 9 cm2. Thickness up to 8 mm
- Macroscopic translator range: 13 x 13 x 13 mm. Manual X-Y
movement, servo-assisted Z movement with 100 nm minimum
step
- Lateral resolution: better than 50 nm, reaching the theoretical
limit for the aperture instruments
- SPM Control System is composed by a digitally controlled analog feedback that combines the flexibility of computer controlled parameters with the high resolution and low noise of an analogue implementation. The electronics supports STM, AFM and SNOM heads, performs different kinds of spectroscopy and can acquire several user-defined auxiliary channels.
- Software runs under Windows and is composed of multi-
window applications to control the instrument and perform the data
acquisition. The software controls all the parameters of the
instrument.
