MF004
MF004 - set of 10 SNOM probes, supplied without tuning forks.
|
Material - single mode optical fiber Nufern 780HP.
Probe tip is coated by Al (70nm)/sublayer V (20nm) .
Tip diameter uncoated by Al (tip aperture) 140 - 220 nm (180±40)
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.
