  • Re: Scanner artefact?

    this issue could be many things. Rounding (as suggested by Stefan K) may work. To truly know the behavor of your scanner it is best to get an image of the calibration grid. Please scan full scan size with 0 deg scan angle on the calibration grid that is 10um pitch and 200nm depth (tapping or contact mode will work fine) and send me an image ( john.tedesco

  • Anodic Oxidation with Nanoman

    I would like to know how to properly format a bitmap, then import into nanoman (specifically v730r1sr3 and NS5 controller on D3100) and have it create an oxidation level that would correspond to a height image following the bitmap when complete. I would need to know what type of sample is suitable, and any sample prep necessary as well. thanks.

  • Re: how to clean the raster sample

    The best way to clean the calibration grid reference sample is as follows: -Buy replicating tape (Ted Pella, product# 44840, ) -Cut a piece of the tape that is larger than the sample size -Place 2 drops of acetone on sample -Place tape over sample while acetone is still liquid -Allow acetone to evaporate

  • NSOM tip 1640-L1 Questions

    -Is it compatable with the nanoscience preamp model# BT00536? -What is the electrical connection on the probe to excite the tuning fork (pin out of 3 pads on assy)? -What is the typical resonance frequency and drive voltage?
