Vacuum Generators HB501 STEM
General:
The HB501 is a dedicated analytic STEM. It is capable of forming a 0.3nm probe operating at 100kV, but is more typically used
with a 1.0nm probe with over 1.0nA beam current. It can also be operated at much higher beam currents but with a loss of resolution.
A double tilt holder is available with +-15 degrees of tilt. The system is fitted with digital scan control, light element EDS and
parallel EELS. The cold field emitter has a very low intrinsic energy width (~0.35eV). EDS mapping and line scanning is available
