Probes -
SNOM
|
 SNOM probes (wavelength 780-1050nm), without tuning forks.
MF004
MF004 - SNOM probes, supplied without tuning forks.
| NT-MDT supply with the optical fibers with the following characteristics: |
Material - single mode optical fiber coated by aluminum
Tip diameter uncoated by Al (tip aperture) ~ 30-100 nm
R curv - 50-100nm
Angle of fiber - about 20 degrees
Maximum optical input power - 400 microWatt
The probes are prepared by chemical etching method.
This method gives the optical efficiency 102 - 104 times better than those obtained by mechanical pulling. |
