Ch. 6. Fluid Imaging in a Droplet Sec. 6.3. Preparing for Imaging
6.3.6. Engaging
6.3.6.1. Pre-engage adjustments
1.
Coarse Engage:
• Pull the scanner forward.
• Using the control wheel on the
instrument base, slowly lower the holder
toward the sample.
• Look down through the glass window
and watch for the moment it contacts
the liquid. You will notice the drop on
the window will disappear and the view
through the glass becomes slightly
darkened.
• Stop lowering the holder when this
happens.
2. Push the scanner into the chassis and close the scanner clamp on the chassis.
Warning
The droplet holder is designed to work only in fluids. Do not try to engage the tip
in air. The software automatically compensates for the refractive index of water.
Focusing on the tip and sample in air will cause the actual distances to be incorrect
and the cantilever will crash into the sample. This feature can be disabled but for
general usage, please only focus the optics through water.
