Dear All,

I have a slite image file that represent a 20microns slit width and I would like to increase it to 25microns. The 20microns slit file is here:

10
0000000000
0000000000
0000000000
0000000000
1111111111
1111111111
0000000000
0000000000
0000000000
0000000000

When I open the Geometric Image Analysis tab, the Field Size is 0.1mm to manifest each line (10microns). The rows with the ones represent 20microns which is my slit width.

Now, how can I make 25microns? I know it is a matter of scaling but I seems not to be able to figure it out and thus I would appreacite your hints.

The reason for this is that I want to test my slit image on the detector and make sure that the slit image is sampled by at least 3 pixels on the detector (FWHM = 3 pixels).

Thank you

Naif
