| So now that we know a little background, let's see how to image a sample with
the low vacuum SEM.
Before imaging can take place, the SEM needs to be "warmed up" for at least an hour to give the vacuum pumps a chance to heat up and evacuate the column. |
 |
 |
When the column is under vacuum, the front panel on the specimen chamber door has the EVAC button lit up. |
| Since the SEM is under vacuum, the column has to be vented first before the specimen chamber door can be opened. |
This is done by pressing the VENT button of the chamber door. |
 |
 |
| The previous sample is then removed. |  |
