Scanning probe microscope (SPM) controller

Power, Speed, and Flexibility

The Asylum Research ARC2 SPM Controller is the most innovative controller for atomic force microscopy. The ARC2, based on the all-digital MFP-3D? Controller, incorporates improved DACs, high voltage relays, a high speed digital
link, and a new design for advanced power and flexibility.

FPGA and Crosspoint Switch Fast and Flexible
The ARC2 combines a fast, low noise FPGA and crosspoint switch for powerful signal routing flexibility. This enables nearly limitless controller configurations, easily set within the software.

High Performance DACs
DAC glitches are practically eliminated with the ARC2s new high performance DACs. Performance is typically 10-20x better than DACs currently used in other commercial controllers.

Software Controlled Relays
The ARC2 incorporates new software-controlled, high voltage relays on the X/Y and Z piezo outputs, and for the laser power. This prevents transients upon powering up and increases the life of the piezos. High voltage relays also allow for cleaner thermal noise measurements, especially when using the Asylum Research Extended Z head (40µm Z scan range).

High Speed Digital Link
All ARC2s come standard with a high speed digital link ready for the next generation of features and functions.

Ready for Solar Applications
The ARC2 Controller is ideal for one of the growing application areas in AFM solar. The software can now toggle the SLD on and off quickly (within a few milliseconds) for measurements on light sensitive photovoltaics. This allows conductive AFM data (ORCA?) to be taken during a second pass with the SLD off, preventing the SLD light from interfering with the current measurement.
