Zemax Releases Performance Analysis for STAR Module, Plus Advanced Ray Aiming and Geometry Enhancements for OpticStudio and OpticsBuilder
OpticStudio® 22.2 features a new Ray Aiming Wizard, along with other enhanced ray aiming improvements and a tool for exporting optical models directly into Ansys Speos
OpticStudio® STAR Module 22.2 adds performance monitoring and FEA dataset control for subscription-based Professional and Premium editions
OpticsBuilder™ 22.2 saves processing time by separating Chief Ray simulation from general simulation, and adds a new Ray Footprint Boundaries tool and Spectrometer sample file
KIRKLAND, WASHINGTON— Zemax, an Ansys company, is pleased to announce the latest release of our three major products: OpticStudio®, our flagship optical design solution; our latest product, the OpticStudio® STAR Module, which simplifies and optimizes workflows between finite element analysis (FEA) packages and OpticStudio; and OpticsBuilder™, which streamlines optomechanical packaging. This version 22.2 is our second release this year.
OpticStudio 22.2: Ray Aiming Wizard, Enhanced Ray Aiming algorithm improvements, and export ability to Speos lens systems
Releases on May 31, 2022
OpticStudio 22.2 feature the following key changes and additions:
Ray Aiming Wizard
This new tool provides data for determining optimal ray aiming settings for your optical system, including settings that are associated with the Enhanced Ray Aiming algorithm released in version 22.1. Located in the Ray Aiming section of the System Explorer in sequential mode, the wizard is especially helpful in system designs where the wrong choice of ray aiming settings can lead to unexpected behavior, such as missing rays or other discontinuities in analysis results.
When you run the Ray Aiming Wizard, it generates a text report listing basic system information and recommended ray aiming settings, along with a summary of the data and decision metrics that it used for its analysis. After reviewing the recommended settings, you can click one button to apply the settings and close the tool.
Enhanced Ray Aiming Improvements
In addition to the new wizard, the Enhanced Ray Aiming algorithm has been improved to include more aperture and field types, thereby supporting more systems by expanding the range of designs where the algorithm addresses "cannot trace" errors and other analysis discontinuities.
The algorithm now allows Entrance Pupil Diameter and Image Space F/# system aperture options, as well as finite object distance support for Field Angle and Theodolite Angle to use with wide-angle systems that have a field of view greater than 180 degrees.
Export ability to Speos lens systems (Professional and Premium editions only)
A new tool for this release enables exporting a reduced-order optical system model created in OpticStudio to Ansys Speos. The model you generate and export can include all relevant parameters of the optical system for simulating optical sensors accurately in a realistic environment. Speos then receives the exported model and integrates the component-level design into a comprehensive system simulation for rendering and visualization.
Currently, the Export to Speos Lens System tool only supports rotationally symmetrical systems. To calculate the reduced-order model, simply define the sensor width and height, the number of sample points, and the number of probing rays. OpticStudio computes a Speos distortion file, and the new export tool reports timing, computed sample points, pupil vector and radius, and focus distance and optical system efficiency for the given pupil, along with ray divergence.
OpticStudio STAR Module 22.2: Performance Analysis across one, many, or all surfaces in an optical design
Releases on May 31, 2022
STAR Module licensed users with a subscription-based version of OpticStudio 22.2 Professional or Premium edition now have a Performance Analysis capability that enables observation of the impact temperature changes and deformations have on optical system performance on a surface-by-surface basis. The tool works by turning FEA datasets on and off, and then monitoring changes in a performance metric you specify, such as RMS Wavefront Error or RMS Spot Size. This analysis will also differentiate between the performance change contributions from 2D structural deformation and 3D temperature data.
These capabilities help you:
Identify which surfaces are contributing to performance change.
Understand the nature of the performance change occurring on each surface.
Predict cumulative performance change as new surfaces are added.
Analyze overall performance change based on all conditions.
Easily report and analyze further by inspecting and copying the analysis data.
OpticsBuilder 22.2: Chief Ray tool improvements, a new Ray Footprint Boundaries tool, and a Spectrometer sample file
Releases on May 31, 2022
OpticsBuilder 22.2 includes multiple enhancements to its Advanced Ray Geometry toolset, including:
A new Ray Footprint Boundaries tool to provide more insights as to whether the optomechanical assembly is meeting the requirements of the optical path. This tool generates ray footprint boundaries on a lens surface based on the sources you specify during setup. By clicking on these boundaries, CAD users can measure, position, and analyze using CAD tools to determine the impacts of their mechanical components on the ray set. These insights empower CAD users to make more informed changes to their mechanical assemblies within their CAD environment while ensuring the assemblies meet ray path requirements.
Timesaving, separate simulation for the Chief Ray tool, introduced in version 22.1, which generates chief rays based on sources the user selects during setup, and then allows for easy analysis within the user's CAD tools for making informed decisions, defining further changes to the mechanical assembly, and ensuring ray path requirements are met. In version 22.2, we've isolated the chief ray simulation from the general OpticsBuilder simulation function, so that users who need it can select it directly from a drop-down menu, while users who don't need it can run general simulations faster by skipping the chief ray analysis portion.

With the new Zemax OpticsBuilder course “Designing Optomechanical Systems with Zemax OpticsBuilder” users can learn the basic concepts of optics required to package, analyze, and validate optomechanical systems and describe how the Zemax ray trace engine calculates and measures optical performance, how to apply the conversion workflow from Zemax OpticStudio to the CAD environment with the OpticsBuilder add-in, understand how to use the vast variety of OpticsBuilder tools on use-case example and how to use the optical drawings feature of OpticsBuilder.
The 22.2 release also adds a new Spectrometer sample file, created with consumer, off-the-shelf parts to more closely imitate exact workflows.
