`Apodization
`Apodization refers to the uniformity ofillumination in the entrance pupil of the system. By default, the pupilis
`alwaysilluminated uniformly, However, there are times when the pupil should have a non-uniform illumination.
`For this purpose, ZEMAX supports pupil apodization, whichis a variation of amplitude over the pupil.
`Three types of pupil apodization are supported: uniform, Gaussian, and tangential. For each type (except
`uniform), an apodization factor determinesthe rate of variation of amplitude in the pupil. See thediscussion on
`apodization types and factors in the chapter "System Menu".
`ZEMAXalso supports userdefined apodizations, which may be placed on any surface. Surface apodizations
`behave differently than pupil apodizations, because surfaces need notbelocatedat a pupil. For more information
`on surface apodizations, see the "Surface Types" chapter under "The User Defined Surface" section.
`Back focal length
`
`ZEMAXdefines the backfocal length as the distance along the Z axis from the last surface madeof glassto the
`paraxial image plane. If no surfaces are madeof glass,the back focal lengthis the distance from surface 1 to the
`paraxial image plane.
`Cardinal planesee_rlee!
`
`The term cardinal planes (sometimescalled cardinal points) refers to those special conjugate positions where the
`object and image surfaces have a specific magnification. The cardinal planes include the principal planes, where
`the magnification is +1, the nodal planes, wherethe angular magnification is +1, the anti-nodal planes, where the
`angular magnification is -1, and the focal planes, where the magnification is 0 for the image space focal plane
`and infinite for the object space focal plane.
`Exceptfor the focal planes,the cardinal planes are conjugateswith each other, that is,the image spaceprincipal
`plane is conjugate with the object space principalplane,ete.If the lens has the sameindexin both object space
`and image space, the nodalplanes are identical to the principal planes.
`ZEMA\lists the distance from the image surface to the various image space planes, andlists the distance from
`the first surface to the various object space planes.
`Chief raymgaSSaa
`If there is no vignetting, and there are no aberrations, the chief ray is defined to be the ray that travels from a
`specific field point, through the center of the entrance pupil, and on to theimage plane. Note that without vignetting
`or aberrations, any ray passing through the centerof the entrance pupil will also pass through the center of the
`stop and the exit pupil.
`Whenvignetting factors are used, the chief ray is then considered to be the ray that passes through the center
`of the vignetted pupil, which means the chief ray may not necessarily pass through the centerof the stop.

`Thedirection of propagation isinitially left-to-right, downthepositive Zaxis. After an a ne oo
`beam physically propagates in a negative Z direction. Therefore,all thicknesses after an odd
`number
`
`should be negative.
`Diffraction limited
`
`The term diffractionlimited implies that the performanceof an optical system islimited by the physical &
`diffraction rather than imperfections in either the design or fabrication. A common means of determir
`
`systemis diffraction limited is to compute or measurethe optical path difference. If the peak to valley OP!
`;
`than one quarter wave, then the systemis said to bediffraction limited.
`
`There are many other ways of determining if a system is diffraction limited, such as Strehl ratio, RI
`
`standard deviation, maximum slope error, and others. Itis possible for a system to be considered diffracti
`by one method andnotdiffraction limited by another method.
`
`On some ZEMAXplots, such as the MTForDiffraction Encircled Energy, the diffraction limited respo:
`optionally shown. This data is usually computed by tracing rays from a reference pointin the field of vier
`
`apodization, vignetting, F/#'s, surface apertures, and transmission may be accountedfor, but the optica
`r
`difference is set to zero regardless of the actual (aberrated) optical path.
`For systems whichincludeafield point at 0.0 in both x and y field specifications (such as 0.0 x angle and0.0
`angle), the referencefield positionis this axialfield point. If no (0, 0) field point is defined, thenthefield coord
`
`of field position 1 are used as the reference coordinates instead.

`Edge thickness
`
`i.
`ZEMAXusestwodifferent definitions for the term "edge thickness", Usually, the edge thickness is computedfor
`a specific surface by:
`rte
`
`=
`
`rl
`
`E..= 24,72, 4T;
`
`Cal
`where Z,is the sag of the surface at the +y semi-diameterof the surface, 2; 1 iS the sag of the next surface at
`the +y semi-diameter of the next surface, and 7;
`is the axial thickness of the surface. Note that the edge
`
`
`thicknesses are computed accounting for the sag at the respective semi-diameter of each surface, which in
`generalaredifferent.

`Note also that edge thickness is normally computed for the +y radial aperture, which may

`The exceptionto this rule is when computing edge thickness solves. Because the ed

`in turn means the semi-diameterof the next surface may change.If the semi-diameter of the nextsucees is used
`in the edge thickness computation,an “infinite loop" orcircular definition may occur.

`For this reason, edge thickness solves compute the edge thicknessstrictly at

`Each analysis window has an "Update" menu item. The update function forces ZEMAX to recompute and
`redisplay the data presented in the window.Thisis useful if the lens data has changed andthe graph now displays
`obsolete data. Double clicking within the window has the sameeffect as selecting Update. Clicking with the right

`Wireframe
`Purpose:
`Draws a wireframe representation of the lens.
`Settings:
`The settings are identical to those available for the Solid Model feature, including support of DXF export.
`Discussion:
`The wnenee modelis identical to the solid model, except hidden lines are not removed. This representation
`may cause
`the screen to becomecluttered with lines. The "Hide Lens Faces" option can be usedto clean up the
`display. The advantageto this display methodis speed: it is faster than the solid model.
`If rays miss a Surface, then the rays will not be drawnto the surface where the error occurred.If the ray is total
`internal reflected, then the ray will be drawn upto butnotpast the surface where the error occurred. Rayfailures
`can be evaluatedin detail by using the Ray Tracecalculation describedlaterin this chapter.
`ShadedMode!
`Purpose:
`Draws a shaded solid model representation of the lens using OpenGL graphics.

`The options are almostidentical to those available for the Solid Modelfeature, except there are additional controls
