CryoView 2000 - Cryogenic AFM 

Nanonics CryoView 2000^TM breaks the barrier of integrating far-field optics with Cryo scanned probe & near-field microscopy. The following unique combination of features is responsible for the transparent integration with optics for bridging AFM, NSOM, Confocal and Raman imaging:

• The 3D FlatScan^TM Scanner Technology
• Cantilevered Glass AFM/NSOM probes
• Breakthrough in Tuning Fork Feedback

CryoView 2000^TM Chamber's Design

CryoView 2000TM Top View

Easy Access to Sample and Probe

The Cryoview 2000^TM scanner port can be opened for easy access to both the sample and the probe without needing to open the entire vacuum chamber. Probes are supplied premounted on a probe holder which includes the tuning fork used for the feedback. Using this probe holder the probe can be easily replaced, accurately and repeatedly. The sample sits directly beneath the scanner port which is located for quick access.

Scanner hinge allows you to easily open The CryoView and expose the probe scanner  & sample which sits under the optical window.

Motorized Sample Positioning

The CryoView 2000^TM X-Y-Z motorized stage controls rough motion in the x, y and z directions with three independently operated stepper motors. This allows for rough motion of the sample in the x and y axis, for easy sample positioning. The motion in the z axis allows manual coarse approach and automatic fine approach of the probe to the surface. The unique design of the stage keeps the sample stage far from heat sources within the chamber and leaves the optical axis completely free.

Large XYZ Scan Range

The CryoView 2000^TM uses the 3D FlatScan^TM technology developed by Nanonics. A novel planar, folded-piezo, flexure scan design allows simultaneous lateral and axial sample scanning. The ultra thin package and open optical axis permits the scanner to be incorporated into systems where conventional scan stages are too bulky and geometrically awkward. The CryoView 2000^TM uses two 3D FlatScan^TM scanners to provide 1nm resolution in the tip scanner and 0.02nm resolution in the sample scanner in the x, y and z directions. The minimal stage height of 7 mm allow for easy access with high powered microscope objectives from either above or below the scanning stage. The large vertical (axial) displacement of up to 70 microns simplifies approaching a sample and allows tracking of structures with very large topographical features. See below for a schematic cross section of the CryoView 2000^TM Chamber.

High Vacuum System

The CryoView 2000^TM is designed around a central 5x10-8 Torr vacuum chamber. Each side of the octagonal chamber is equipped with a port to add flexibility to the system. When used for low temperature work, a vacuum pump station is connected to the chamber and evacuates the cryostat for operation at an interim temperature of <25 K. The chamber can be connected to a high vacuum pump station and a transfer line from a dewar that contains the cryogen for low-temperature operation at temperatures down to 10K.
