Performance


Automated inspection of large samples and samples arrays with ultimate positioning precision
 

 

VEGA is the first AFM that brings industry standard automation to all users:

  • All routine procedures like area of interest exchange, laser alignment, gentle approach and scanning parameters tuning are fully automated
  • Motorized sample positioning stage is correlated with optical image allowing 1 um positioning accuracy on 200×200 mm area
  • Prolongated serial measurements of large and multiple samples became easy and time-effective thanks to smart algorithms, user interface for multiple AFM measurements and database image storage


 


 

Ultimate resolution of closed-loop wide-range scanner and sensitivity of optical beam deflection (OBD) sensor
 





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

Perfect environment for high-resolution measurements 

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. Unique design of fan free enclosure provides Vega with capability to operate at conditions of extraordinary temperature stability within 0.05 C. This guarantees the exceptional low thermal drift of less than 0.2 nm/min.
