Q: Can the geometries of optomechanical parts such as housing (the pipes) be imported in Optics Builder when modeled outside the system?A: The geometry of optomechanical parts can be created either in the same assembly file in which you import your ZBD file or outside the system, in another Creo instance. If the latter is the case, you may open the optomechanical part in the assembly file and mate it using the reference geometries (including those you generated out of the optical components). OpticsBuilder recognize all the imported optomechanical parts and see them in ray-tracing.I hope this helps. Please let me know if you have any other questions.
@Ece İlkay.Sungur Q: thank you.A: My pleasure!And thank you for attending the webinar. Please let us know if you have any questions or there is anything we can help with.Best regards,Moj
@Patrick.Maeda Q: For the optical system used in the OpticStudio-OpticsBuilder-OpticStudio STAR Module Interoperability in Design of High-Power Laser Systems Webinar, were any ghost reflections accounted for in the thermal/structural analysis? If not, why not and how could the light from ghost analysis be incorporated? Would it simply be to split rays when performing the analysis?A: Yes, ray splitting was enabled when running the NSC analysis to compute the absorbed irradiance in the optical system. We set all the objects, both optical and mechanical as detectors to record absorbed irradiance. Without ray splitting then rays would only have hit the lenses and mirror, and we wouldn't have seen any light incident on the mechanics.In the NSC file, using filter strings you may see rays that hit , for instance, the “barrel” and “laser tip” objects.You can read more information in this knowledgebase article: STOP Analysis of high-power laser systems - part 4 – Knowledgebase (zemax.com)I hop
Hi James,As for the first part of your question, STAR module is only available in sequential mode, and in sequential mode you won’t be able to directly import a STP file into your lens file for STOP analysis.As for the second part of your question, X,Y,Z Position and Tilt parameters of a NSC object set position and orientation of the object local coordinate system with respect to the global coordinate system, assuming the Ref. Object is 0. You may visualize the local axis in the 3D layout through Object Properties...Draw as shown below:The CAD object local coordinate system is defined inside the CAD platform when saving a STP file. So, you may have two options here; first you can have your mechanical engineer define a local coordinate system in Creo to properly position and orient the CAD component in the local system and then customize the STP export by selecting the defined local system, and second, you can define a Null object with your desired orientation in NSC mode and then refer
Hi Paul,OpticsBuilder is an add-in for Creo that provides CAD users with the tools needed to build, analyze and share their work. Using OpticStudio-OpticsBuilder workflow, a live version of the lens design including lenses materials, geometries and positions, optical properties and information about sources, system wavelengths, and detectors can be generated in OpticStudio in ZBD format to be imported into OpticsBuildr. OpticsBuilder then automatically creates native CAD parts of all optical components. So, CAD users can access the optics reference geometries to design the optomechanics in Creo Parametric, and then analyze the optomechanical components impact on the system optical performance, in terms of Spot size change, Beam clipping and Image contamination, using the OpticsBuilder built-in ray simulation engine. After finalizing the optomechanical design, another ZBD file including both optics and optomechanics can be exported from OpticsBuilder to be opened back into OpticStudio
Hi Alberto,Without being able to see your file it is hard to make a comment. Do you have a file to share here so that I can take a closer look and get a better understanding of the issue? It would be helpful if you could share both the ZAR file and the STP you exported using the Parasolid libraries. Thanks.
Hi Chris, I already emailed you the response, but I post it here as well in case other users come up with the same question.The Biconic Zernike Surface is described by the following sag equation: which is not necessarily the same as the Aspheric surface sag given the higher order aspheric terms (X^4 and Y^4 in your model): This can be seen by superposition of the two surfaces in the 3D Layout: That's why the illumination patterns are different with Biconic Zernike and Aspheric Surfaces.Best regards,Moj
