Probe Holder

The apparatus that physically connects the SPM probe to the microscope is referred to as the Probe Holder. In the case of AFM probes, the probe holder may also be referred to as the Cantilever Holder. For most systems, this apparatus is a separate component from the scanner head, although this is not always the case.

For the Dimension Icon Scanner

The probe holder for the Dimension Icon scanner is a small printed circuit card or acrylic block that holds the probe substrate firmly at the proper angle. The standard holder is used for operation in air, while a holder with a clear glass window is used for fluid cell operations. Probe holders include the cantilever piezoelectric stack, electrical contacts to the drive circuits, and gold-plated spring sockets that mate with the gold-plated pins at the end of the scanner. There is also a spring-loaded clip to secure the substrate to the probe holder assembly.

The probe holder on the scanner is easily swapped as required for different Imaging Modes.

For the Dimension FastScan Scanner

The Dimension FastScan system is unique in that the probe holder is incorporated into the removable Z scanner. Consequently, Dimension FastScan does not require the user to change probe holders for air versus fluid applications. This also means that the Dimension FastScan scanner is not designed for Scanning Tunneling Microscopy (STM) or other applications that require specialized probe holders. It is nonetheless capable of operating a wide range of AFM Imaging Modes.

For the MultiMode Head

The probe holder for the MultiMode system inserts into the stationary head, which rests above the scanner. A variety of probe holders are available, each optimized for a particular imaging mode. The substrate is held on the probe holder via a spring-loaded clip and the entire assembly is brought into electrical contact with the microscope using a clamp in the rear of the head.

Caution/Attention/Vorsicht:

Some early-model AFM probe holders may electrically short out power supplies when used with the MultiMode. If you suspect your probe holder is from an older AFM, check with Bruker or your international representative before using.
Certains modèles de support de bras de leviers pour AFM de contact peuvent endommager les alimentations électriques quand ils sont utilisés avec un MultiMode. En cas de doute, contacter Bruker ou son représentant légal pour verification.
Einige ältere Ausführungen des AFM-Spitzenhalters können einen Kurzschluß verursachen falls sie mit einem MultiMode-AFM verwendet werden. Bitte wenden Sie sich im Zweifelsfall an Bruker bzw. an die für Sie zuständige Bruker-Vertretung.

For the Innova Head

The Innova system uses a two part probe holder. In the case of AFM probes, the probe is mounted on a ceramic chip carrier, which is then inserted into the probe cartridge for mounting in the SPM head. Probes may be purchased unmounted, in which case they are then inserted by the user into the unmounted chip carrier and the chip carrier is inserted into the probe cartridge. Users may also purchase pre-mounted probes, which are bound to a non-reusable chip carrier. STM

probes are inserted directly into the STM cartridge and do not require a separate chip carrier. Ensure you select the appropriate probe holder for your application.

For the Bioscope Catalyst Head

The probe holder for the Bioscope Catalyst is a small dovetailed block that holds the probe substrate firmly at the proper angle. The standard holder is used for operation in air, while a holder with a clear glass window and inlet/outlet ports is used for fluid operations. Probe holders include the cantilever piezoelectric stack, electrical contacts to the drive circuits, and a spring-loaded clip to secure the substrate to the probe holder assembly.
