OMCL-AC240TM Replacement AFM Probes

Olympus Corp. have decided to stop producing their well-known AFM probes, also known as Olympus*** Micro Cantilevers, which have been on the market for a very long time.

For detailed information on how the different types of our AFM probes compare to the Olympus AFM probes please read our guide to OLYMPUS*** Replacement AFM Probes.

Below is a list of AFM probes that can be used as replacements for the Olympus*** OMCL-AC240TM electrically conductive AFM probes with nominal resonance frequency 70kHz (range 50-90kHz) and nominal force constant 2N/m (range 0.6-4.6N/m), also known as AC240TM. This AFM probe type has a 240µm long AFM cantilever beam with a triangular end. The three-sided AFM tip is at the very end of that the AFM cantilever and has a 90° end flank. The AFM probe has a platinum coating on the tip side and aluminum reflective coating on the back side of the AFM cantilever.

The OPUS 240AC-PP is the perfect alternative to the AC240TM. In form, fit and function these AFM probes are duplicates. The AFM cantilever length as well as the mechanical properties are the same. The AFM cantilever shape as well as the AFM tip shape match. The 240AC-PP differs from the AC240TM only in that the former features an overall platinum coating on both sides of the AFM cantilever, making the OPUS AFM probe chemically inert and thus stable in aggressive measurement environments.

The OPUS 3XC-NA and 4XC-NN AFM multi-lever AFM probes both feature an AFM cantilever with the same mechanical properties and the same AFM tip shape as the AC240. The first model is available without a reflective coating – 3XC-NN.

The NANOSENSORS™ ATEC-EFM features a three-sided protruding AFM tip at the end of the triangular AFM cantilever end that makes real tip visibility possible even when the AFM probe is mounted onto the AFM head and therefore tilted. The AFM cantilever length and overall shape are the same as with the Olympus*** AC240TM AFM probe. From a mechanical parameter point of view the ATEC-EFM has a slightly higher nominal resonance frequency and a stiffer AFM cantilever compared to the AC240TM.

The NanoWorld® ARROW-EFM features a three-sided, slightly inclined AFM tip at the end of a triangular AFM cantilever end. The AFM cantilever length of the Arrow-FMR is identical to the AC240TM from Olympus*** and the overall AFM cantilever shape is similar. The nominal resonance frequency is the same as the AC240TM AFM probe and the stiffness is slightly higher compared to the AC240TM

The MikroMasch HQ:NSC18/Pt and BudgetSensors ElectriMulti75-G AFM probes offer similar resonance frequencies to the AC240TM and slightly higher force constants. They are cost effective alternatives to the AC240TM for electrical characterization AFM measurements (e.g. EFM and KPFM). The polygon-based AFM tips are positioned some micrometers away from the free end of the AFM cantilevers. Uncoated and reflective gold coated versions are optionally available for each type.

Original Olympus AC240TM AFM probes were sold by Bruker Corp. under different name - OSCM-PT. For customers looking for the same order code and matching specifications we offer the OPUS OSCM-PT.
