Punte TOP VISUAL per noncontatto (frequenza di risonanza tipica 300 kHz, costante di forza tipica 50 N/m), rivestimento riflettente di Al.

 

TOP VISUAL NONCONTACT Silicon Cantilevers VIT_P/IR series

 TOP VISUAL probes intended:
1.  For precise positioning of the tip over the point of interest and for direct real-time observation of sample scanning and modification (nanomanipulation) processes.
2. For precise positioning of a tightly focused laser spot at the tip end - for investigations of optical effects between tip and sample (TERS, TEFS, s-SNOM etc).
