ZOS-API- How to use tools like Set Variable, Optimization, Tolerancing, Calculate RMSspot etc.?

TheSystem.Tools. SetAllRadiiVariable(); TheSystem.Tools. SetAllThicknessesVariable (); Set all radii variables Set all thicknesses variables LocalOpt = TheSystem.Tools.OpenLocalOptimization(); LocalOpt.Algorithm = ZOSAPI.Tools.Optimization.OptimizationAlgorithm.DampedLeastSquares; LocalOpt.Cycles = ZOSAPI.Tools.Optimization.OptimizationCycles.Automatic; LocalOpt.NumberOfCores = 8; LocalOpt.RunAndWaitForCompletion(); LocalOpt.Close(); Run local optimization with DLS GlobalOptimTimeInSeconds = 15; GlobalOpt = TheSystem.Tools.OpenGlobalOptimization(); GlobalOpt.Algorithm = ZOSAPI.Tools.Optimization.OptimizationAlgorithm.DampedLeastSquares; GlobalOpt.NumberToSave = ZOSAPI.Tools.Optimization.OptimizationSaveCount.Save_10; GlobalOpt.RunAndWaitWithTimeout(GlobalOptimTimeInSeconds); GlobalOpt.Cancel(); GlobalOpt.WaitForCompletion(); GlobalOpt.Close(); Run global search and cancel it after 15 seconds HammerOpt = TheSystem.Tools.OpenHammerOptimization(); HammerOpt.RunAndWaitWithTimeo

Material of same name in two different active catalogs

QUESTION: I have two catalogs in my “Catalogs To Use” section of the System Explorer. Both catalogs have a material named “Glass1” in them, but it is defined differently in each catalog. Which catalog will it draw from if I use “Glass1” in my Lens Data Editor? ANSWER: If there are materials of the same name in multiple catalogs, OpticStudio will use the material from the catalog that is higher on the “Catalogs to Use” list. As an example, imagine the material “Glass1” is in both the SCHOTT and ALOHA catalogs. If it is used in the LDE, it will be pulled from the SCHOTT catalog because it is defined above ALOHA.

NSDD not working in Universal Plot

QUESTION: I am using the Universal Plot and have NSDD as my Dependent Variable. When I press OK I get the error “Some of the operands cannot be computed!”. Why is this? ANSWER: Instead of using NSDD as the Operand for the dependent variable, it must be set to Merit, and the Line should be set to NSDD: This is because to use NSDD like many other Non Sequential operands, the detectors should be cleared, and a ray trace must be run. This can be done by using blank NSDD and NSTR operands prior to the NSDD operand you are trying to plot in the merit function:

How to add more lines to the Fit Index Data tool

QUESTION: how do I add more than 3 lines to the Fit Index Data tool in the Materials Catalog? ANSWER: Press Insert on your keyboard to insert more lines into the Fit Index Data editor. Also, if you have the data in a text format similar to the one shown below, it can be saved as a .DAT file and can be loaded in with the “Load Index Data” button.

Tolerancing with Merit Function Criterion violates compensator min and max

QUESTION: I am running a tolerance analysis with Merit Function as the criterion. However, the min and max values for the compensators go beyond what is called out in my Tolerance Data Editor after the tolerancing is run. Why is this? ANSWER: If you are using Merit Function as the criterion, you must define boundaries to the compensators in the Merit Function Editor and not in the Tolerance Data Editor. Use optimization operands such as PMLT (Parameter less than) and PMGT (Parameter greater than) as well as other boundary operands to apply these boundary conditions.

Coating Multiple Faces of CAD Part

QUESTION: I have imported a CAD part that has over 50 faces. I would like to put a coating on each face. Is there a way to coat all the faces at once? ANSWER: Yes, there is! Go the CAD tab in the Object properties for the CAD object. In the Model Parameters section, change Surface Mode to “Use Single Surface”. Now the whole object will be represented by a single face.

Edge Thickness Operand

QUESTION: Is there an optimization operand that ensures that there is air space between lenses when I have chip zone set to non-zero?   ANSWER: There are a couple ways you can do this depending on if you are targeting multiple edge thicknesses or just one. If you are just targeting one, try using the ETGT (Edge Thickness Greater Than) operand. If you leave Code and Mode as 0, it will constrain the Mechanical Semi-Diameter along the +Y axis. Whatever surface you put in, it will make sure that the thickness to the next Mech Semi-Diameter is greater than your target. Just set the target to be 0, and it will make sure that the Chip Zones do not cross over each other. If you want to target multiple surfaces, try using MNET (Minimum Edge Thickness). This will allow you to put a range of surfaces to be greater than the specified value. Again use the Mechanical Semi-Diameter by entering “0” in the Mode column.

CAD Export

QUESTION: When I am running the CAD export, I am getting one surface that is failing to export. What is going on? ANSWER: First it is important to note that if there are apertures on some surfaces they may not be exported. As an example, spider obscurations are not currently supported by the CAD export. If there are no apertures, sometimes the CAD export has trouble with complex shapes and the surface tolerance will have to be changed. To do this, go into the surface properties of the CAD part and go to the CAD tab. In the CAD tab change the Surface Tolerance to a smaller value like 1E-5 or 1E-6.   If this does not fix the problem please send the file to Zemax Support so we can debug it!
