LockIn-Amplifier	Level AFM

• Simultaneous Acquisition of Almost Unlimited Number of Pictures
  (limitation starts for example at 20 pictures with 512 pixel due to the PC)
• Integrated distance control (IP controller) with over 6 different feedback modes
• Slope correction during scan free parameter input during scan
• 4 different types of spectroscopy (any signal vs. distance, any signal vs voltage, ...)
• Computer controlled coarse positioning and automated approach
• Adapable to almost all hardware due to
  • free scalabity of all channels in physical units
  • offset correction for each hardware channel
  • sign inversion possible
  • relation between hardware channel and name is open
• Additional adjustment for user specific setups:
  • number of steps for stepper motor approach
  • delays and repeat times for slip stick controls

SPM Software:

• Image Acquisition with GNU GPL (Generell Public License = Open Source Software)
• Filtering (High-Pass, Low-Pass, Fourier Trasformation, Noise Filtering)
• 3D-View
• Line Subtraction, Plane-Subtraction by Selectable Area
• Date Import/ Export (*.txt, *.bmp, *.img etc)
• Image/Data Information-Switching for Each Image
• Brightness/Contrast
• Zoom and pixel-rescaling
• Color/Tool Palette Selectable
• Display of Scan-Information
• Image Copying to Clipboard or Saving as BMP for Data Presentation
