Sigma LBA-708 Elliptical Pass/Fail, Gauss Pass/Fail, Top Hat Pass/Fail, Centroid, Orientation

3.3.2.2Centroid

The Centroid Pass/Fail item allows you to define a circle that must contain the centroid of the beam energy. To implement this test you must define the location of the center of a circle in terms of its X and Y coordinate in the beam display window, and the Radius of the circle that must contain it.

Both the X and Y Centroid location results will change color from GREEN to RED should the centroid fall outside this circle.

3.3.3Elliptical Pass/Fail

The following results may be set in the Pass/Fail Elliptical… dialog below the main menu Pass/Fail item.

3.3.3.1Orientation

The Orientation Pass/Fail item applies to the major axis inclination of an Elliptical beam. The units for these two edit controls are always in degrees. The Major axis can tilt through an angle in the range of +90 to -90 degrees. You can set the desired tilt Angle, and a +/- Range around this angle, that will meet your testing criteria. The Rotation result will change color from GREEN to RED should the angle fall outside of these set limits.

3.3.4Gauss Pass/Fail

See the Pass/Fail Gauss… dialog below the main menu Pass/Fail item for a list of these items.

3.3.5Top Hat Pass/Fail

See the Pass/Fail Top Hat… dialog below the main menu Pass/Fail item for a list of these items.
