`

`This feature is similar to the 2D DXF export feature described in the previous section. The key difference is
`that the 3D DXF supports systems that are not rotationally symmetric.
`Miscellaneous
`Reverse Elements
`Purpose:
`Reverses a lens element or group.
`Settings:
`
`Item
`
`First Surface
`
`Last Surface
`
`Description
`
`This is the first surface of the lens group to be reversed.
`
`The last surface of the lens group to be reversed.
`
`Discussion:
`The feature may not work correctly in all cases if mirrors, coordinate breaks, multi-configuration controlled
`data, surface tilts and decenters, or non-standard surfaces are included in the range of surfaces. Check the
`reversed system results carefully to verify that the desired result was achieved.
`Tilt/Decenter Elements
`Purpose:
`Tilts or decenters a single surface or a group of surfaces forming an element.
`Settings:
`
`Item
`
`First Surface
`
`Last Surface
`
`Description
`
`This is the first surface of the lens group to be tilted/decentered.
`
`The last surface of the lens group to be tilted/decentered.
`
`Decenter X, Y
`
`The X and Y decenters in lens units.
`
`Tilt X, Y, Z
`
`Order
`
`The rotation about X, Y, and Z in degrees.
`
`Either tilt then decenter, or decenter then tilt.
`
`Coord Brk Color
`
`Selects the spreadsheet display row color for the inserted coordinate breaks. See “Row
`Color” on page 71 for a description of Row color.
`

`
`B r k
`
`The comment string for the inserted coordinate break surfaces.

`Dummy Surface
`
`If checked, any trailing dummy surface inserted as part of the tilt and decenter tool
`modifications will be checked with the options "Skip Rays To This Surface" and "Do Not
`Draw This Surface". See “Surface properties draw tab” on page 72.
`
`Discussion:
`The feature inserts coordinate break and dummy surfaces as required to tilt and/or decenter a single surface
`or a range of surfaces. For more information on coordinate breaks see “Coordinate Break” on page 256.
`Scale Lens
`Purpose:
`Scale will scale the entire lens by the specified factor. This is useful for scaling an existing design to a new
`focal length, for example. Wavelengths are not scaled. The scale lens feature may also be used to change the
`units from mm to inches, or other combinations of unit types.

`Description
`
`Scale by factor
`
`If selected, then a scale factor may be entered directly.
`
` Scale by units
`
`If selected, then the lens will be converted by the selected units.
`
`Discussion:
`Scaling of data is performed based upon the units of measure for the data. If the scale factor is X, then data
`measured in lens units of length will be scaled by the factor X. Data measured in units of lens units squared (such
`as millimeters squared) will be scaled by X squared. Some polynomial coefficients, such as those on the Even
`Aspheric surface, have units that change from term to term, and ZEMAX accounts for this when scaling the data.
`Other parameters, such as the conic constant, are dimensionless, and are therefore not scaled.
`ZEMAX will generally scale all lens data in the Lens Data Editor, the Extra Data Editor, and the Non-Sequential
`Components Editor correctly. ZEMAX also will scale almost all of the data in the Merit Function Editor, the Multi-
`Configuration Editor, and the Tolerance Data Editor correctly as well.
`ZEMAX will not attempt to scale some types of data, even though scaling would be appropriate for those types
`of data. These exceptions are for data items such as the multi-configuration operand PAR3, that modify general
`parameter data of surfaces or objects. These data items should be scaled manually, if required.
`Data items that are not scaled properly should be reported to ZEMAX technical support.
`Make Focal
`Purpose:
`Make focal length is similar to scale lens, except the desired focal length is typed in directly. The entire lens is
`then scaled to make the focal length the specified value.
`Quick Focus
`Purpose:
`Adjusts back focal distance for best focus. See also “Quick Adjust” on page 228.
`Settings:
`
`Item
`
`Description
`
`Spot Size Radial
`
`Focus to best RMS spot radius image surface.
`
`Spot Size X Only
`
`Focus to best RMS x direction spot size image surface.
`
`Spot Size Y Only
`
`Focus to best RMS y direction spot size image surface.
`
`Wavefront Error
`
`Focus to best RMS wavefront error image surface.
`
`Use Centroid
`
`Reference all calculations to the image centroid rather than the chief ray. This option is
`slightly slower, but more appropriate for systems dominated by coma.
`
`Discussion:
`This feature adjusts the thickness of the surface prior to the image surface. The thickness chosen is that which
`minimizes the RMS aberration. There are several different RMS computations that may be performed as
`described in the "options" table above. The "best focus" position depends upon which criterion is selected. The
`RMS is always computed as a polychromatic average over the field, using the defined fields, wavelengths, and
`weights.
