WebTypical line scan rates for commercial AFMs imaging biological samples are between 0.5 and 10 Hz. This results in imaging times ranging from 13 sec for very low resolution images scanned “rapidly” (128 x 128 pixels scanned at 10 Hz) to 512 seconds for “high resolution” images scanned at moderate speed (512 x 512 pixels scanned at 1 Hz). Webscanners are designed so that their mechanical resonance frequencies are much higher than those of conventional scanners [6,13]. These high resonance frequency scanners have …
