Mode Plot Mode PlotThe Mode Plot displays the cavity mode on a graph. It is useful for visualising the mode without the complication of the two-dimensional layout of the canvas.
In the upper part of the Mode Plot window, the entire cavity is displayed, with the cavity optics distributed according to their spacings. The highlighted rectangle indicates the range over which the mode is displayed in the graph. You can drag the highlight rectangle and change its width using the mouse.
In the lower part, a standard graph displays the cavity mode. You can change the axes limits by clicking near the ends of the axes to open an edit box. Or, you can edit the axis range properties in the Property Manager.
The mode plot properties are divided into the Graph and Canvas groups.
