Load-Lock Transfer of Specimen
For fast preparation cycles and to minimize
contamination inside the fracturing system, the specimen can
be loaded through a load-lock transfer system. The load-lock
can also be used for reloading the electron beam guns.
Precise fracturing with microtome
LN-2 cooled fracturing knife with manual or
motorized motion. Precise control of microtome advances with
stepper motor.
Control of specimen temperature
Ideal for freeze etching with precise
specimen temperature control. For freeze etching of
fractured surfaces the specimen temperature can be
controlled tightly. Peltier elements are used for precise
temperature ramping of the specimen stage. Above the
specimen a LN-2 cooled shutter prevents any contamination of
the specimen
Electron beam source angles can be preset
from 0 to 90°
for shadowing and replication (Carbon layer at 90°).
Stationary or rotary shadowing is possible, offering a wide
range of shadowing options, including "DARS" (Double axis
rotary shadowing).
Hydro-carbon free high vacuum pumping
system
A turbo molecular drag pump assures
hydro-carbon free operation of system
