[オンラインセミナー] 携帯電話用レンズの光学設計：概要と設計のための基礎知識 [Q&A]

このスレッドでは、オンラインセミナー開催前に質問を投稿でき、セミナー開催中に頂いたご質問にお答えしていきます。お気軽にご質問を投稿してください。また、このトピックに関する追加のディスカッションをご覧になりたい場合は、このスレッドを Subscribe（購読）してください。このスレッドは 12 月 1 日までコメントを受け付けています。タイトル：携帯電話用レンズの光学設計：概要と設計のための基礎知識日時：2022 年 11 月 24 日（木）14:00-15:00 参加リンク：https://attendee.gotowebinar.com/register/718411428057837579?source=communityプレゼンタ：アンシス・ジャパン株式会社マネージャーアプリケーションエンジニアリング池田　賢元（イケダ　カツモト）アブストラクト：光学レンズ設計の手法は100年以上前から進化を続けており、今日ではレンズ設計はZemax OpticStudioをはじめとするコンピューターソフトウェアによって実施されています。特に、プラスチックレンズが持つ自由度とソフトウェアを搭載したコンピュータの計算能力が相まって、プラスチックレンズの光学系の光学設計はかつてないほど高度なものとなっています。複雑な光学系の光学設計の一例として、携帯電話のレンズ設計があります。今回のプレゼンテーションのテーマは、スマートフォンに使用される設計プロセスです。典型的な携帯電話用レンズを用いて、光学設計のプロセスを分解して説明し、光学設計プロセスの手順を調査します。携帯電話用の光学設計のコンセプトから、最適化までのプロセスを光学的な観点から説明します。光学設計に続き、携帯電話の光学系の機構設計を説明し、更に生産に向けた設計を説明します。最後に、レンズの熱・構造の影響を検討し、環境要因のSTOP分析を加えます。プロセスが光学設計のバーチャルプロトタイピング（仮想試作）の例として、光学設計をより早く、効率的に生産に至るまでのヒントとなれば幸いです。

POP simulation using Toroidal lens

I’m using a lens that on both sides is Toroidal. When making Physical optics propagation, what are the things I need to be aware of in order to make a correct propagation? One thing I noticed is the ‘Separate X-Y’ , any other issues?

Tolerance data visualization - Histogram and Yield icons grayed out and non-functional

Currently running OpticStudio 20.2 Professional.  Trying to use the Tolerance data visualization functions (Histogram and Yield) for the first time, but they are grayed out and non-functional.  The tolerance data viewer is working and displays the results data set.  I have run a short Monte-Carlo set and saved the files.  How to I engage the Histogram and Yield functions?

TEZI tolerance operand error message

HelloI am having problems running a tolerance analysis that only uses the TEZI operand. I get the error message that says “TOFF requires surface 0 to have a physical sag” which makes no sense. You can see the screen shot in the image attached. I think this is a bug in the software.Any ideas?RegardsDiego

Faster way to "Clear & Trace" in OpticStudio

Dear all,I'm looking for a quick way to retrace rays in OpticStudio (“Clear & Trace”) that doesn't require 3 mouse clicks. A button or shortcut doesn't matter. My current workflow is:open the modal dialog Ray Trace Control, hit the button close the dialog knowing that I'll have to reopen it in a couple seconds after adjusting parameters.The simplest fix would be to keep the Ray Trace Control dialog always open, but it's modal so it locks the main window while open.Any good advice for iterative processes involving ray tracing?Thanks, Matthias

User Defined Surfare shows only 12 Parameters in LDE

I am new to DLL programming for Zemax. I have an older file using the Fixed-Data 3 standard. This should support 201 parameters. Unfortuneatly in the LDE editor a maximum of 12 Parameter columns are generated even if i define more. Is there a cap of how many parameters can be displayes as input in the LDE?

ISO Element Drawing: open issues

I'd like to point out some mandatory features which, in my humble opinion, the ISO Element drawing utility lacks. I'm probably referring to all well known issues, but still, I believe them to be of paramount relevance to be left unsolved over the years. 1) support for triplets. 2) xml file support for doublets/triplets. More on this, I report a sneaky behaviour of the current feature: if a doublet design is saved, no error is reported by OpticStudio and an empty xml file is saved instead, so that the average user can believe its manually inserted data are securely saved, but actually they are not. When opened, such xml file just reports the string 'XML output is not currently supported for doublets'. 3) drawings saving in a native vector format, such as pdf or svg. At the present time an external pdf printer sw is needed to do so, often with unpredictable results. The same request holds for every graphic output of OpticStudio (diagrams, histograms, plots,...).

Universal_Plot value not matching with operand value

Dear Support team, Can you please assist with the below error? I am trying to plot RAID operand value vs Y-Filed angle (-1 to +1degree). But the value in Universal Plot and Merit Function Editor does not match.Could you please have a look at the attached files and let me know the correct setting for the universal plot. Can you help to take a look at it and advise?Thanks in Advance!

Quadrant Detector

I am modelling a laser position detection system. I wanted to know if OpticStudio comes with commercially available position detectors like quadrant detectors. If yes, any leads on how to find them in zemax. If no, how does one go about a situation where you have to use a commercially available detector in Zemax.

2D laser waveguide simulation: import electric field norm from txt file

Hi,I created a 2D simulation of a waveguide in COMSOL as shown in the figure (semiconductor laser).semiconductor laser simulation in COMSOLit is an intensity plot showing the electric field at the edge of the waveguide. From here I can extract x,y and z (electric field) into a .txt file. How can I import this data into OpticStudio? Thank you

image aberration balance with unknown lens design data

Hello everyone, I’ve been racking my brain to try to figure out the image aberration balance method with unknown lens design data method, which isthe camera is put at the final image plane, the current final image is not so good. the problem is the there is an unknown design in this optics train, so I can neither adjust nor redesign the latter components to balance the final image aberration. I come up with a method which is: i put an image aberration sensor at the first image plane, the sensor would read out the first image aberration in terms of Zernike coefficients, then I start a new design, i put a dummy surface which contains the first image aberration in terms of Zernike coefficients at the first image plane position. and then I can adjust or redesign the latter components in this optical train. Do this method make sense?

Homogenizer

Hello,I’m trying to design beam homogenizer and checking several concepts: rectangular rod and fly’s eye lens.In my case the source is quite large, 10.4x7.5mm.I looked at Zemax sample file: Digital_projector_flys_eye_homogenizer.zmx.The source size is 0.25x0.25mm. Up to about 1x1mm the design works good. Increasing source size decrease the beam parallelism hitting the fly’s eye which reduce dramatically performance.Do you know if this concept can work with larger source as in my case: 10.4x7.5mm.s quite large, 10.4x7.5mm.I looked at Zemax sample file: Digital_projector_flys_eye_homogenizer.zmx.The source size is 0.25x0.25mm.

能否在进行公差分析时同步读取出各个蒙特卡罗公差文件的FFT Through Focus MTF数据呢？

我在数据处理上遇到了一些小问题。我需要模拟分析镜头生产过程中的DOF分布。（同时满足三个或者四个视场的MTF规格的像面离焦范围）我想寻找一种快捷简便的方法，我现在使用的方法太浪费时间了。我现在采用ZEMAX的蒙特卡罗公差分析，并保存了1000个蒙特卡罗文件。然后用ZPL宏读取这1000个蒙特卡罗文件的FFT Through Focus MTF数据分别输出为1000个TXT文档。然后用matlab对FFT Through Focus MTF数据进行处理。我正在用ZOSAPI简化这个小程序，但是这样能节约的时间有限。我想知道的是，我们能否在zemax进行蒙地卡罗公差分析时读取出每一个蒙地卡罗文件的FFT Through Focus MTF数据。而不是像我现在一样，必须保存这1000个蒙特卡罗文件，再进行加载文件，读取数据；加载文件，读取数据。。。。我这样这太浪费时间了。附件里是我写的ZPI宏和matlab源文件。以及matlab计算脚本打包后的程序。里面肯定有很多不足，希望能获得一些建议。
