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.

What Our Users Are Saying

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.”
