[Raytrace] User Defined Optimization Set Up

[John D. Upton]

List,

     Has anyone tried to set up custom optimization operands in OSLO LT?  I 
cannot seem to divine from the help files how (or if in LT) this is 
done.  Do I need to write CCL routines to add custom OCM words or is there 
a way to enter the conditions directly?

     As an example (the one I am working on), how can I put conditions on a 
spacing in a design.  Let's say I want to modify a Dall Null test setup for 
Ross Null test use.  Further, I want the final image plane to be coincident 
with the source plane.  Here is a basic setup.  (Dimensions are in 
millimeters.)

*LENS DATA
Ross Null 14" F/4.4
  SRF      RADIUS      THICKNESS   APERTURE RADIUS       GLASS  SPE  NOTE
  OBJ       --         90.604489 V  9.0604e-05             AIR
  AST   100.000000      5.000000      9.707008 AS          BK7 C

   4        --     P   -5.000000 P    9.449479 S           BK7 P
   5    100.000000 P  -88.213944 S    9.261180 S           AIR
  IMS       --         -0.048925      0.005229 S

*CONIC AND POLYNOMIAL ASPHERIC DATA
  SRF        CC          AD          AE          AF          AG
   3      -1.000000      --          --          --          --

     Now, what I want is to force an optimization condition so that 
thickness 5 is equal to thickness 0 (though in the opposite direction).  In 
other words, I would like to add the equivalent OCM command word for 
optimizing both total spherical aberration (OCM20) and th[0]+th[5].  Anyone 
done something like this before?
