Scanning

• The panel Scanning Range defines the initial and final values of the scanning parameter and the number of intervals (number of points minus one).
• The panel Scanning of has an obvious meaning. The first option Fixed Parameters corresponds to the General and Layers page parameters.
  - Scanning of Layer Thickness enables the Check Box Bunch. This control checking implies the total thickness of selected layers scanning preserving their relative thicknesses.
  If it is necessary only changing at ones the Bunch of Layers Thickness, press OK → Optimize → Variable Parameters, edit Bunch of Layers Thickness and press Export → Settings to return back.
  - The Cell Length is normalized for the period and its scanning has two options. The unselected or disabled Check Box Center implies that a sum of lengths of given Cell and the next Cell is constant. The selected and enabled Check Box Center (this is possible only for number of cells more than two) implies that the given Cell center position is preserved and a sum of lengths from previous to the next Cell is constant.
  Note The Bunch option is used in Optimization Dialog and cannot be edited from it.
• If the check box in the 2D scan of panel is checked then the user can get diffraction efficiency versus two different parameters from the Scanning of panel list. The diffraction efficiency order and component can be selected in the Diffraction Orders Output panel and in the 2D scan of panel Combo Box. Scanning parameters, range and number of scanning points can be selected individually for rows and columns under appropriate 2D scan of option.
• The other controls: Output Format, Output Decimal Digits and Diffraction Orders Output define the representation of result data in the edit window.
  In the panel Diffraction Orders Output the user can choose any range of displayed diffraction orders restricted by minus plus of a half Number of Modes. Near by the appropriate fields there are tips about the extreme indexes of diffraction orders in the whole range of scanning which are updating with the changes of scanning range parameters.
• The conical mount version contains the Output Polarizer control. This control has an effect only on the result data representation and not on the actual calculations. For more details see Slider.

A one dimensional scan is represented in an appropriate graphics window. See the Graph Dialog.
A two dimensional scan is represented in the 3D Graph window.
