SNOM_C
SNOM_C - a set of 10 SNOM aperture cantilevers for contact mode.
Lever sizes and the pyramid position
Pyramid LxWxH = 20x20x13 (70 deg)
Tip shape and aperture size
Pyramid (SiO2) thickness 400-600 nm
Coating: Al, about 100 nm, coating from bottom side. Bottom FIB milling should is done after coating. Typical aperture diameter is about 120 nm ± 25nm.
