Details

Standard silicon nitride cantilever for DC (contact) mode AFM and LFM

OLYMPUS pyramidal tip (below) is stably sharpened by our special fabrication process, and its small radius of the tip are achieved. OLYMPUS introduced this type of the tip in the first time in the world in 1991. You never doubt this type of the tip becomes standard for contact mode AFM measurements.
The tips are made of silicon nitride, which is less prone to wear than single-crystal silicon. This helps to minimize image changes caused by wear of the tip.

Tip
• The pyramidal tip is sharpened toward the tip apex.
• Tip shape : sharpened square pyramidal (hollow tip)
• Tip height : 2.9 µm
• Tip radius : less than 20 nm (15 nm (typ.))
• Tip angle (face to face) : 25 - 45 deg. (top to around 300nm down)
• Tip material : silicon nitrid

Metal reflex coating
Thin gold/chromium film is coated on the back side of the cantilevers for reflecting light from a deflection sensor in the AFM equipment. Transparency of the lever with reflex coating for visible light is 1% or less.

Applications
• Contact mode AFM operation
• When the sample is easy to damage.
• Contact mode LFM/AFM operation
• AC mode AFM in fluid.
• The 100µm long cantilever of the TR400PSA- is also recommended for AC mode AFM in fluid.
