Scout HAR Silicon AFM Probes High Aspect Ratio Probe Tips

Reliable imaging every time.  Rigorous inspection of every probe means each one performs as you expect. Pack of 10 AC mode silicon AFM probes with a high aspect ratio tip.  Ideal for deep trench imaging with non-contact/tapping modes in air, on hard samples, and stable softer samples.

Available:
   Uncoated.
   Aluminum backside coating. 
   Gold reflective backside coating.

High aspect ratio: Cone angle of < 15 ° over the final 1 μm of the tip.   Minimal variation in spring constant and resonant frequency.
