OpticStudio Release Notes

Ansys Zemax OpticStudio 2024 R2.02 Release NotesMinor Release

2024 R2.02 Release NotesSeptember 11th, 2024 1 Tools, Features, and Capabilities 1.1 Stress Birefringence Addition (Enterprise edition) STAR tools support Stress Birefringence data and analysis Stress Birefringence is a consequence of mechanical stress acting on a transmissive optical material due to the photoelastic effect. It is a physical effect that is becoming increasingly relevant for complex systems using injected-molded lenses, such as automotive HUDs, augmented reality headsets, and cell phone camera lenses. Many of these systems are sensitive to polarization changes throughout the optical path including those that come from internal stresses due to the manufacturing process or mechanical stress from the optic's mounting. The effects of these stress-induced polarization changes can now be imported into STAR so that you can model the effects of stress birefringence. New options in the STAR Performance Analysis and STAR System Viewer enable you to monitor the effects. The ima

OpticStudioリリースノート

Ansys Zemax OpticStudio 2024 R2.02 リリースノートサービスパック

2024 R2.02リリースノート2024年9月11日 1 ツール、機能及び利便性 1.1 応力複屈折の追加（Enterpriseエディション） STARツールにて応力複屈折データ解析をサポート応力複屈折は、光弾性効果によって透過型光学材料に機械的応力が作用することで生じる現象です。これは、射出成形レンズを使用する複雑なシステム、例えば自動車のヘッドアップディスプレイ (HUD) 、拡張現実ヘッドセット、スマートフォンのカメラレンズなどにおいてますます重要性を増している物理現象です。これらのシステムの多くは、製造過程で生じる内部応力や、光学部品の取り付けによる機械的応力に起因する偏光の変化に対して敏感です。この応力によって生じる偏光変化の影響は、現在STARでインポートすることが可能であり、応力複屈折の影響をモデル化できます。STARのパフォーマンス解析とシステムビューアに新たなオプションが追加され、これらの影響を確認することが可能になりました。上記の画像は、標準的な光学システム（左）と応力が加わった光学システム（右）におけるOpticStudioの [偏光瞳マップ] (Polarization Pupil Map) を示しています。応力複屈折の影響は、標準的なOpticStudioの解析だけでなく、STARのシステムビューアやパフォーマンス解析ツールを使用して定量化できます。 1.2 合成面：NSCへの変換をサポート（すべてのエディション）合成面がノンシーケンシャルモードで使用可能 [NSCグループに変換] (Convert to NSC Group) ツールを使用して、[合成面] (Composite Surface) をノンシーケンシャルモードに変換する機能が追加されました。変換プロセスの中で、シーケンシャルモードの合成面で積算されたサグ量が、ノンシーケンシャルモードの [複合レンズ] (Compound Lens) オブジェクトの前面または背面の対応する [グリッドサグ面] (Grid Sag Surface) としてに変換されます。この強化により、合成面がより強力にサポートされ、ノンシーケンシャルモードのシミュレーションや解析がより柔軟に行えるようになりました。 1.3 LSWM Static Link – xy空間変形のサポート (す

OpticStudio 版本说明

Ansys Zemax OpticStudio 2024 R2.02 版本說明Minor Release

2024 R2.02 版本說明2024年9月11日繁體中文:1 工具、特性與功能 1.1 新增應力雙折射功能（僅支持於OPTICSTUDIO企業版）STAR模組如今將支援應力雙折射資料和分析應力雙折射是由於光彈效應引起的機械應力作用於透射光學材料的一種結果。這是一種物理效應，其對於包含射出成型透鏡的複雜系統越來越重要，如汽車抬頭顯示器HUD、擴增實境頭戴設備和手機攝影鏡頭等。通常這類系統對整個光路中的偏振變化很敏感，包括那些來自製造過程引起的內部應力或光學元件安裝時的機械應力所引起的偏振變化。現在，這些應力引起的偏振變化效應可以導入到 STAR 中，從而可以模擬應力雙折射的影響。STAR 性能分析和 STAR 系統檢視器中的新選項使您能夠查看這些影響。上圖描繪了名義光學系統（左）和應力光學系統（右）中的OpticStudio偏振光瞳圖。應力雙折射的影響可以使用標準OpticStudio分析以及STAR System Viewer和STAR Performance Analysis工具進行量化。 1.2 複合表面：支援轉換為非序列模式（支援於所有版本）複合表面如今將支援於非序列模式中現在已經支援通過“轉換為 NSC”工具將複合表面轉換為非序列等效面。在轉換過程中，序列模式下的總複合堆疊矢高會被轉換為非序列複合透鏡物件的前表面或後表面的等效網格矢高表面。此增強功能進一步支援複合表面，從而實現更靈活的非序列模式模擬和分析。 1.3 LSWM 靜態連結 – 支援XY空間變化量（支持於所有版本） LSWM 現在支援光柵的空間變化 LSWM靜態連結外掛程式已更新，現在支援基板上光柵的空間變化。光柵形狀、週期和方向可以是笛卡爾坐標系或極坐標系的函數。與現有的工作流程類似，需要從Lumerical生成副檔名為 .json的檔案資料。檔案格式現已更新，支援空間變化。更多詳細資訊可以參考如下文章：Lumerical Sub-wavelength Model: Introduction and Data Generation – Ansys Optics。 1.4 匯出光線光跡圖至CAD（支持於所有版本）光線光跡圖有助於防止意外的光機干擾在序列模式下，您現在可以將光線光跡圖作為圖層匯出到CAD物體上。在匯出CAD檔工具中，有一個復選框允許您將此匯

Part designer object disappearing in NSC 3D Layout

Hello all, I have built a part using part designer that I cannot seem to locate when inputting it into the NSC 3D Layout after I scale it down to the size I want it. This scale has never been an issue when building other parts, however those were typically made using Sketch mode and were much simpler than the part I have currently built. My current part was made using elliptical volume 2, mirroring it, and then using the array function to propagate the shape into one long, repetitive object (no gaps between the object array). Once built, I use the scale function to bring the shape from millimeter to micrometer scale. Through all of this, there are no errors within Part Designer. When I load the object into the NSC editor, I receive no errors. However, when scaled to the um size, the shape cannot be found in the NSC 3D Layout. This is problematic for me, as I cannot visually see it to know how to manipulate my system. The scaling of this part seems to give me the issue, as scaling it d

Quarter wave plate with added phase error (Jone matrix)

HelloI want to simulate the effect of a quarter wave plate that creates an additional shift in the polarization of lets say 10° in a plarimeters. The polarimeter is comprised of a lens, collimating the polarized beam, a quarter wave plate, and an analyser plate. To determine the polarization state, the quarter wave plate is rotated azimutally by 180°. With the data I calculate the stokes parameter. It all works fine for the ideal case, but not for an added phase shift between both polarization states.I am using the Jones matrix for the exact quarter wave plate in the form of:A_real=1A_img=0D_real=0D_img=1the result for this quarter wave plate is as expected. The result is the same when I use, for testing purpose, the non-factored version Jones matrix of the quarter wave plate:A_real=0.707A_img=0.707D_real=0.707D_img=-0.707Now I add to the lambda/4 phase shift an additional shift of 10° in the Jone matrix, which results in the Jones matrix in Zemax notation:A_real=0.573576A_img=0.819152

CAD object face number limit?

I’m trying to simulate a chrome-on-glass target in non-sequential mode by assigning a OD transmission coating to each dark face as shown in the image below.When I import the CAD as step file, all the surfaces above 50 are all assigned to face 0. It’s like there are only 50 faces allowed? Is there any way around this?I’ve tried importing with .igs with the same problem.Importing with .stl doesn’t include the individual faces.any suggestions or pointers?

Want to annular lens design and see the paths inside the minimum radius and through the lens

Hello all, I have some questions about designing the optics. In sequential mode, I change the aperture to ‘Circular aperture’ for the annular lens. But ‘Circular aperture’ blocks the lay in the inner hole. I want to know how to make an annular lens that can pass the lay into the inner hole. It’s no matter sequential or non-sequential mode. Thank you,

OPD Plot Varies when selecting "all" wavelength vs an individual wavelength?

When I select OPD Fan for a 5 degree field, I get this:These are the settings used. However, when I now select just 1 wavelength (same field, same system), I get something completely different in my “OPD Fan” values: The system is the exact same in both cases, and I confirm that the values change in the text version when selecting a single wavelength. Does this have to do with “lateral color” and how it is displayed in the OPD Fan plot (I expect my system to have lateral color for reference)? Or is it something else?Lateral Color (plot + in system diagram) for reference:System Information: I am modelling a GRIN (Gradient Refractive Index) lens design using a custom *.dll (nothing too fancy, just adds in wavelength dependence based on custom materials) extensions. This is a singlet that I was testing for off-axis light. Edit:Same effect happens if I switch x/y fields around: Where OPD when selecting one wavelength doesn’t match the other.

Python ZOS-API, example not working out of the box since Ansys

The example script for the interactive mode in Ansys Zemax OpticStudio 2024 R1.03 does not work out of the box. It manages to find the path of the ZOSAPI_NetHelper.dll from the windows registry (path is to C:/Users/username….) but it says:Exception: Cannot find OpticStudioI don't know why this automatic path is not found, if I put manually the path inside the script (line 24):pathToInstall = r'C:\Program Files\Ansys Zemax OpticStudio 2024 R1.03'It works! Not sure if it is related that I used Zemax before it was acquired by Ansys and it is looking in the wrong location.Just for those who'd like to use the zospy library, you can also pass the path directly:import zospy as zpopticstudio_directory = r'C:\Program Files\Ansys Zemax OpticStudio 2024 R1.03'zos = zp.ZOS(opticstudio_directory=opticstudio_directory)oss = zos.connect("extension")Perhaps it helps others to save some time.

How to minimise distortion

Hi everybody,I have come across an impass in zemax. My problem statement says that I have three lenses separated by some distances. I have to move the distance between these lenses. The problem that is occurring is "distortion aberration" in the system. I've tried to use some operand to reduce distortion by making the radius of curvature variables and now the distortion is absent in the system for a particular set of distances between the lenses. Now, when I am trying to move the lenses again, the distortion increases again. Pictures are attached for your reference. One where distortion is zero and other when the distance between lenses have increased and the distortion increases simultaneously.I request you to guide me so that I can move my lenses without getting distortion in the system.Any help will be appreciated.ThanksFig.1: Distortion is 0 for a particular distance (10mm distance between lens 1 and lens 2, and lens 2 and lens 3) Fig.2: Distortion increases when the distance betw

Opticstudio crashes when saving an image

Hello, I have a file with CAD objects, Boolean Native objects, and a simple optical system.Every time I try to save an image of the NSC Shaded Model Window OpticStudio crashes. I have tried to save as .bmp and .png which both make it crash. .jpeg is the only format that will save the image without crashing.Is this a known issue or is there a setting making it crash?I tried to change hardware and software blending as well.Thank you.

Set inner surface of a detector polar to be Lambertion scatter

Hi, I set up a hemisphere detector polar. I want it to be a Lambertian target as well. I set it to be reflective, scattering model to be Lambertian, scatter fraction to be 1, number of rays to be 5, and importance sampling. But I don’t think it is working. Could you show me how to set up this correctly.
