How to Pivot Any Element About Any Point in Space

The coordinate breaks in OpticStudio are extremely flexible. Coordinate breaks can be used to tilt or decenter any optical surface, or group of optical surfaces, about any pivot point, without disturbing the rest of the optical system.
In this article, I’ll show how to tilt a lens about its front vertex without disturbing the rest of the optical system. I’ll also use global coordinates to check that the system remains undisturbed. Then I’ll move on to tilting a lens about its center, and finally I’ll demonstrate tilting a lens about an arbitrary point in space.

Array ray tracing in Zemax OpticStudio from Python using the DDE extension

This article describes how to trace large number of rays in Zemax OpticStudio using a Python-based DDE1 extension called PyZDDE.

1Although the DDE extension has been superseded by the new and excellent .NET based extension in the latest release of OpticStudio, Zemax will most likely retain the DDE interface for the foreseeable future.

Troubleshooting UI Issues in OpticStudio

This article explains what to do if you install OpticStudio and experience a slow user interface. There are a number of preferences and settings that can be changed to help speed up the UI. If you are experiencing other installation problems, please see the Troublshooting your OpticStudio Installation Knowledge Base Article.

This article will walk you through the following troubleshooting steps:
  • Checking for graphics driver updates from the manufacturer
  • Changing your Project Preferences
  • Checking your Non-Sequential Settings
  • Getting help from Zemax

Multi-threaded Optimization in Zemax OpticStudio

Zemax OpticStudio is designed to exploit all the CPUs in the user's computer without any user intervention. It will automatically determine the optimum number of threads to launch for any given calculation, including during optimization. One question the engineering team often encounters is why CPU usage seems to be single threaded during optimization. This article specifically addresses that topic.

Interfacing to OpticStudio from Mathematica

This article provides an example of the standalone method, in which the external application is Mathematica. A Mathematica notebook is used as a user interface and scripting language. It will start an OpticStudio session, load an existing lens file, manipulate that lens file to alter the lens design, perform an analyses, and obtain and process the results to provide information not directly available through OpticStudio.

Freeform Optics in OpticStudio

OpticStudio provides a number of tools for the design of Freeform Optics in both sequential and non-sequential modes. In this article, we’ll provide an example of an off-axis parabola using the Chebyshev Polynomial surface in sequential mode. We’ll also describe filtering tools available in the Lens Data Editor that quickly allow you to find the freeform surface of choice for any desired application from the more than 20 such surfaces that are currently supported in sequential mode.
