Three atomic force microscopes are available for use in the Roy J. Carver Laboratory for Ultrahigh Resolution Biological Microscopy of the Institute for Combinatorial Discovery.

Digital Instruments DimensionTM 3000 Scanning Probe Microscope

The Dimension 3000 scanning probe microscope (SPM) brings together all SPM techniques in a single platform and handles a wide range of sample sizes and types. A rigid, low vibration construction of the Dimension 3000 SPM ensures the highest quality images and measurements.

Samples up to eight inches in diameter can be scanned in ambient air or fluids using the Dimension 3000 SPM. The Dimension 3000 SPM requires little or no sample preparation, and the simple vacuum mounting system allows easy and convenient setup. Superior linearity and resolution in all three dimensions are obtained, even for large samples. Integrated top-view video optics with motorized zoom and 1.5 µm optical resolution help identify areas of interest for detailed scanning quickly and easily. Changing scanning techniques, for example from AFM to STM, requires no tools.

The NanoScope IIIa system controller is a main part of the SPM system, providing the software and electronics that drive the microscope. Digital tracking and feedback control insure accuracy and speed at all scan sizes and positions on the sample.
