Drift-free imaging

Drift-free Imaging 

Continuously imaged for one week, this 250 nm scan of gold on glass was taken at 1 Hz and at 256 x 256 pixels. The acoustic hood was left open for 12 hours and closed at the start of imaging. Built-in image stabilization fixes the XY position in place to within a few nm’s. Additionally, attractive mode imaging prevents the tip from blunting as evidenced by comparing the first and last frames.
