STM Vibration Control
Remove Vibration Noise from Your STM Today
For over 25 years, Herzan has been helping scanning tunneling microscope (STM) users achieve more from their research by removing disruptive vibration noise from affecting their STM. Vibration noise can cause distortions to occur in the imaging, making understanding the data collected less precise. Learn more about our proven strategies and solutions by reviewing a case study highlighting the benefits of active vibration control on surface analysis techniques for STMs.
Omicron STM supported by an array of AVI-200S active vibration isolators
“(W)e first tried air legs, but these actually increased our problems with vibrational noise. I believe the reason for this is that the air legs gave the system additional freedom to move and so vibrations from stainless steel gas tube lines more effectively coupled in to our system, resulting in increased, rather and decreased noise. I will also be reporting back to my service contact at Omicron with the success of the active vibration isolation.”

MEMS + TS Series
The Turner Group is using interferometry to measure the deflection on an AFM probe. The instrument is being used to investigate adhesion and surface properties of nanoscale materials for MEMS applications. Despite being placed on an air-based isolation table, the instrument’s measurements
Researchers at Essilor USA observed a substantial amount of vibration noise limiting their Keyence VK-X250 3D Laser Scanning Confocal Microscope. The resulting vibration noise affected their surface roughness measurements, resulting in inaccurate results. To combat these issues, Essilor worked with Herzan to discover the best solution for their instrument given the severity of their environment: the TS-140 active vibration isolation table.
The Zewail Group operating a Quanta FEG 650 interfaced with a custom optical set-up to enable ultrafast electron microscopy imaging. Feeding laser into SEM chamber requires positional stability within a few micrometers, so SEM internal air isolation was not in use.
There are three instrumentation setups in the Baker Group that make use of the AVI-200 active vibration isolation system. Our studies are mainly focused on scanned probe microscopy, where is a nanopipette filled with electrolyte is used to either map the local ion current of a given sample or to obtain a
