MF002

MF002 - set of 10 SNOM probes, supplied without tuning forks.

Material - single mode optical fiber Nufern 460HP. Probe tip is coated by Al (70nm)/sublayer V (20nm) . Tip diameter uncoated by Al (tip aperture) ~ 50/100 nm 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.
