25Pt400B

Versatile probe with a lower spring constant: 8 N/m (± 40%)

The 25Pt400B is similar to the 25Pt300B, but with a lower spring constant. It is often used in when smaller spring constant is needed.
Material: Solid platinum probe tip and cantilever supported on standard AFM probe sized ceramic chip, connected to conductive gold bonding pad with conductive epoxy.

  • Tip shank length: 80 μm (± 25%)
  • Cantilever length: 400 μm (± 15%)
  • Cantilever width: 100 μm (± 15%)
  • Spring constant: 8 N/m (± 40%)
  • Frequency: 10 kHz (± 30%)
  • Tip radius: < 20 nm

Probes designed specifically for the Keysight (Agilent) Scanning Microwave Microscope (SMM) add-on have the letter A rather than B (ie 12Pt400A).

Technical Features

Material: Solid platinum or platinum-iridium probe tip and cantilever supported on standard AFM probe sized ceramic chip, connected to conductive gold bonding pad with conductive epoxy. RMN also has probes available without gold contact pad, to help reduce stray capacitance. 
Probes on standard sized substrates have a part number ending in the letter B (i.e. 25Pt300B).
 
Probes designed specifically for the Keysight (Agilent) Scanning Microwave Microscope (SMM) have the letter A rather than B (i.e. 12Pt400A).
 
Additional substrates:
  • C - Substrate without gold bonding pad, to help reduce stray capacitance (= to A dimensions)
  • D - Substrate has a 200um gold transmission line the entire length of the chip  and the back is completely covered in gold (standard size chip)
  • E - Substrate has the same features as the D substrate, only it is thinner (5 mil thick)
