- length of the high aspect ratio portion of the tip > 2 µm
- typical aspect ratio at 2 µm in the order of 7:1 (when viewed from side as well as along cantilever axis)
- (when viewed from side as well as along cantilever axis !)
- half cone angle at 2 µm of the high aspect ratio portion typically < 5°
- guaranteed tip radius of curvature < 15 nm
- highly doped to dissipate static charge
- high mechanical Q-factor for high sensitivity

The reflex coating is 30 nm thick aluminum coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the cantilever. The virtually stress-free coating is bending the cantilever less than 2 % of the cantilever length.
