Outstanding features of new Tetrahedral cantilever

Application for various sample surfaces:

The mid-range mechanical properties [resonance frequency: 150kHz, spring constant: 9 N/m (typ.)] mean that the OMCL-AC200TS-R3 is tailored to any surface from soft to hard.
The stiffer middle mechanical properties [resonance frequency: 300 kHz, spring constant: 26 N/m] means that OMCLAC160TS-R3 is redesigned for revealing sample surface precisely and gently.

Doped silicon cantilever:

The cantilever is made from silicon with a low surface resistance of 0.1 - 0.4 Ω・cm.
This means 1/20 resistance of our conventional cantilevers.

Acclaimed 'TipView' structure:

The probe can be easily positioned at the exact point of your interest. The probe is located at the exact end of the cantilever so that the probe apex is not obscured during optical observations.

Ideally point terminated probe:

The probe is tetrahedral, ideally point terminated. The probe apex 1 micron or more is further sharpened.

New concept chip:

The ideally parallel side-walls of the chip make tweezing easy and eliminate problems with chipping and debris.

note

Many researchers in biology and chemistry field have interests in AC mode AFM in fluid. For measuring a soft sample like a biology cell, OMCL-TR and -RC series cantilevers are recommended rather than OMCL-AC series cantilevers. See the sample images taken by OMCL-TR400PSA- and OMCL-AC120TS-.

Metal coating

[Reflex coating]

Thin aluminum film with the thickness of 100nm is coated on the cantilever for reflecting light from the deflection sensor in the AFM equipment. High reflex for high S/N sensing can be expected.

Packaging

Miscellaneous

  • Care for Static shock (see an example of tip damage)
    The sharper tip needs the more careful handling to prevent static damage to the tip. Use of an anti-electrostatic mat and a wrist band are recommended as when handling laser diode chips. Handling under an ionizer is also recommended.
    Please avoid wearing clothes like woolen sweaters, fleece etc when handling the cantilever cases and chips.
  • We guarantee more than 90% good cantilevers in this product series. Every good cantilever meets the specifications.
