Light-Field System LF4-CUBE

Removes contamination from samples and holder shafts
No re-contamination during observation
High-vacuum holder station: less than 1X10-4 Pa

Remove Contamination Mecanisum

4ports High Vacuum station
less than 1X10-4Pa(spec.)

Halogen lamp annealing
Removes contamination

The annealing temperature is adjusted by
height using the our original thermometer.

A plasma cleaner cannot remove contamination over the entire holder surface, though it is effective for cleaning just the sample. That is, a plasma cleaner cannot perfectly clean the holder; the sample would be re-contaminated by residue materials from the holder shaft when observed by TEM.

Important points
1. All surfaces of both the holder and sample need cleaning.
2. Plasma damages the sample.

The LF4 system can clean both your sample and the entire holder surface under light and high vacuum without any sputtering damage. This improves your TEM and STEM data.

LF4 Other option and functions

Other three functions

Extension Ports
Various expansion chambers of options
can be installed using this.

Skewer Valve
You can used as port when pumping
Cryo holder Dewar.

Thermometer probe
The annealing temperature is
adjusted by this.

Other option chambers

EX4 additional station
4 ports can be added using the extension port.
The same applies to LF4, but the port shape
can be selected one by one.

Multi port Chamber 8
Each TEM Holder, SEM stage and
your samples cleaning by Plasma Clean.
You can make use of 6 ports in any way.
