Zemax Optic Studio will automatically look up this glass in its database to determine the index of refraction of the material at each design wavelength.
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: F, d, C (Visible) is the first option by default.
To access the Field Data Dialog, select Fields in the System Explorer, or double-click on “Settings”.
For the purposes of the singlet design, we will define the fields in terms of angle.
However, choose the current design wavelength by first selecting Once the system settings have been defined, information specific to each surface can be entered into the Lens Data Editor.
To reiterate, each row in the LDE represents a single surface.
Since the stop will be located at the front surface of the singlet lens, insert another surface (representing the back face of the lens) by placing the highlighted cursor in the row of the IMA surface, and pressing the “Insert” key: The Comment column in the LDE can be very helpful in keeping track of what each surface represents.
