SX-50 and SX-100 microprobes database (Dept. of Geosciences, UMass Amherst) | Print date: 04/19/2021 (08:52)
Calculate the right setting for your WDS element mapping or load an existing one from the list aside the title.
Enter X (horizontal) and Y (vertical) coordinates for the region to map. Value for top (or right) must be higher than value for bottom (or left).
Maximum values in μm constrained by the stage limit are...
- LEFT (X) = -23637
- RIGHT (X) = 25634
- TOP (Y) = 40291
- BOTTOM (Y) = -43615
- LEFT (X) = -25278
- RIGHT (X) = 25033
- TOP (Y) = 42591
- BOTTOM (Y) = -39632
These limits can be adjusted in the file "preferences.inc.php"; ask your webmaster!
Select the EMP to use. This will only limit the maximum number of pixel per map.
Choose your calculation option on the right and enter on the left the required value:
- Image size in pixels along X or
- Image size in pixels along Y or
- Step size in micrometer per pixel.
Note: the maximum image size is ...
- 1024 pixels for SX-50
- 2048 pixels for SX-100.
ONLY AVAILABLE WITH THE OPTION "STEP SIZE"...
If checked, this options will force a maximum size for your map. It will take the maximum amount of pixel allowed at the selected electron microprobe, and multiply this value by the selected step size. It will then adjust the X position (left and right) in consequence. This can be useful for full thin section map, or to get the largest map at a specific step size.
Choose your calculation option on the right and enter the time constraint on the right:
- Dwell time (countintg time on each pixel) or
- Total acquisition time (in hours or minutes).
