Ambios Quesant Universal SPM is available in our laboratory.

Quesant Universal SPM features include:

• 250x video microscope with 90 degree top-down view for easy alignment and positioning of the AFM probe. Tip and surface view is 45 degrees during STM operation.
• Easy-to-use controls permit rapid probe exchange and alignment, sample approach, and intuitive display and adjustment of all SPM operating parameters. There is a micrometer-driven X-Y translation of the scan head over the sample.
• Contact and non-contact AFM imaging modes.
• Patented Analoop™ analog PID feedback loop that is digitally controlled which allows more accurate data gathering and has an extremely fast sampling frequency.
• Acoustic/Vibration Isolation Chamber (AVIC)

Staging Systems :

• Maximum sample size: 25(x) x 25(y) x 8(z)mm
• X-Y translation: +/- 5mm (manual)
• Sample mounting: 20mm diameter platform
• Simple exchange of scanners, probe modules (i.e. AFM to STM), and cantilevers
• Video view: 250x, 0.75mm FOV, 90° to sample
• Sample illumination: LED

Realtime image acquisition software features include:

• Realtime surface leveling
• Adjustment to PID controls
• Adjustment of scan controls
• Undo/redo functions to allow capture of previous or partial images
• Image capture up to 1024 x 1024 pixels
• Slope shading or perspective illumination
• Hardware and software image zoom

Image analysis and rendering software features include:

• Variety of curve fitting/leveling mechanisms on a line-by-line or entire image basis
• Image streak and/or spot artifact removal
• 2D FFT analysis with unique image conjugate erase functions that allows easy identification and removal of periodic features
• Line profile extraction on single or multiple lines
• Automated bimodal histogram function for statistically significant step height measurements
