MultiMode Hardware Description

The MultiMode application module hardware consists of the following items:

Application Module AFM Scanner

Allows the user to mount the application module using two springs (see Figure 1). A single modified head platform supports any one of the four five modules at a time. Modules are quickly and easily exchanged and installed to facilitate analysis of the same sample by complementary, alternative techniques.

Application Module Sensor

You may mount the application module sensor on the application module AFM head using two screws. It connects to the NanoScope V Controller 37-pin adapter using the subminiature D-15 connector (see Figure 2).

Application Module Probe Holder

Made from non-conductive materials, the probe holder, shown in Figure 3, maintains standard features for contact mode and tapping mode imaging while reducing electrical noise.

TUNA, SSRM and C-AFM share a common probe holder.

Electrostatic Discharge (ESD) Protection Jumper

Of the currently available MultiMode application modules, three are ESD-sensitive (TUNA, SSRM and C-AFM). These are supplied with a tiny Static Protection Jumper (see the loop of wire extending from the application modules on the right of Figure 4).

Probe Module Universal Connector

All Dimension application modules are provided with a tiny wire, the Probe Module Universal Connector (Universal Connector), shown in Figure 5, which is required when a module is in use.

EMI Shield for TUNA

Given the low signals and high gains associated with Tunneling Atomic Force Microscopy, electrical noise can become an issue. To reduce this noise, Bruker recommends using the EMI shield, shown in Figure 6 and provided with the TUNA Application module.
