Perfect environment for high-resolution measurements: build-in acoustic&vibration isolation and thermal stabilization system



High-resolution measurements require exceptional level of acoustic and vibration isolation of AFM working environment. Build-in acoustic enclosure and active anti-vibration system makes VEGA perfect for demanding AFM studies.


Thermal drift is a challenging issue for high-resolution and long-term measurements especially for large-sample AFMs with massive mechanical parts. Tranfer of all heating parts out from working volume and build-in thermostabilizing system with 0.05 oC accuracy allow less than 10 nm/hour thermal drift.

 

 

Ultimate signal-to-noise ratio of optical beam deflection (OBD) sensor

 

  850 nm non-coherent superluminiscent diode (SLD) source and special optical scheme design assures the lowest 25 fm/√HZ OBD sensor noise among commercial large-sample AFMs.

 


 

Low-noise closed-loop wide-range scanner



Our unique piezoscanner and control electronics design allow atomic resolution while saving wide, 100×100 μm scanning range.
