Using the sources window

The sources window is where you specify the field of view, the source divergence, and the wavelengths of light.

How to open the sources window:

  1. Select from the menu System > Sources

missing graphics
Field type popup
Using the Type popup menu, select how you wish to specify the field points. Options are:
  • Field angle (degrees)
  • Object height: coordinates on object plane
  • Paraxial image height: object height times paraxial magnification
Field table
Enter x and y values, in the units specified by the type popup (degrees or mm). Color of the field (used in plots and layout views) is specified here. The ordered color or random color button may be used to color all fields at once.
Divergence popup
This popup is used to select how you will specify the divergence of the cone of light emitted by the point sources. Options are:
  • Entrance pupil diameter
  • Float by stop size: uses the semidiameter of the stop surface
  • Object space N.A.: specify sine of the emission cone half angle
  • Object cone angle (degrees): specify the cone half angle
  • Infinite conjugate image space f/#: specify focal ratio as if object were at infinity
  • Paraxial working f/#: specify focal ratio for the actual working conjugate
Wavelengths
In this table enter the wavelengths in units of nanometers (nm). This information is saved in objects called "waves". Color of the wave (used in plots and layout views) is specified here. The ordered color or random color button may be used to color all waves at once. The F,d,C button replaces the contents of the table by the standard visible wavelengths.
