Punte super affilate di carbonio diamond-like (DLC) con un raggio di curvatura tipico di 1nm cresciute sulla sonda della serie NSG01. Super sharp diamond-like carbon (DLC) tips* with typical curvature radius 1nm are extremely useful for obtaining high resolution on objects with sizes of several nanometers. DLC tips have very long lifetime due to the high material durability.

DLC tips can be grown on any standard probe series.

To guarantee 20nm working length of DLC tips TEM is used. 10% from total number of probes in the batch are selected for testing. At least 80% of those probes should have the only DLC tip which lengh is exceeded by 20nm others DLC tips on the same probe. In this case the whole batch is considered as passed the TEM test. On the surfaces with roughness bigger than 20nm double images are possible.
