Wavelength data is entered into ZEMAX much like field data, only the wavelengths are entered into the Wavelength Data dialog.  You may access the Wavelength Data dialog by selecting System > Wavelengths from the main menu, or by pressing the “Wav” button on the button bar.

Wavelength Data dialog

This singlet design is purely monochromatic (pertaining to a single wavelength).  From the inital design specifications, the wavelength which will be used is 0.6328mm...the wavelength of a HeNe (Helium Neon) laser.

This wavelength may be manually typed into the Wavelength Data dialog, or it may be entered by selecting one of the pre-programmed wavelength options in the pull down menu near the bottom of the Wavelength Data dialog:

Selecting Pre-programmed Wavelengths

F, d, C (Visible) is the first option by default.  However, choose the current design wavelength by first selecting HeNe (.6328) from the pull-down menu, and then pressing the “Select ->” button which is next to the pull-down menu.  ZEMAX will automatically place this wavelength into the first entry:

Note that wavelengths in ZEMAX are always entered in microns, regardless of the system lens units!

Click "OK" to close the Wavelength Data dialog and apply the defined wavelengths.

Note that wavelength weights are also supported, and are used for various purposes within ZEMAX.  However, for the scope of this design, all wavelength weights will remain unity.
