显微镜光学成像系统设计案例分享

Hi Dujin,感谢您的提问。首先这个案例使用了infinity corrected tube lens. 该案例所展示的是两个子系统（objective lens + tube lens）分别设计，然后结合在一起。关于使用infinity corrected tube lens 的优点请查看下面的网络资源：https://www.olympus-ims.com/en/microscope/terms/feature15/因此这个距离的设置与两个子系统镜头各自的厚度和总系统总长要求有关。两个子系统中加入的倾斜45度的元件的用途是分光，本例中并未包含分出去的光路。这也是infinity corrected光路的优势，可以在中间加入其他元件，使整个系统的自由度更高。我们知识库文章中有共聚焦显微镜的案例，其中就增加了分光平板分出去的那束光这支光路。关于共聚焦的显微镜的设置及用途请参考网络资源。Thanks,Julia

ZOS-API: How to save/load a .FLD file into a system

Unfortunately, the function is not included in the ZOSAPI methods list. Therefore, it is not possible to use it directly to save and load fields, as in the UI. However, the .fld file saves the field type and each field's values in the field data editor with the following format(utf-16). To apply these values to your system's field data editor table as the "fld" way, save this data as a text file. Please refer to the provided Python code.Save and load field data in Python, use the following functions that are defined in the attached file:To save field data, use the SaveFields(TheSystem,filepath)function. To load field data, use the LoadFields(TheSystem,filepath) function.

Extended source line/edge spread

To calculate the geometric edge/line spread feature, statistical calculations were performed using the (built-in) Spot Diagram.We can make additional use of the results of geometric image analysis by setting the Show option to "Spot Diagram" in GIA, then switching to the text tab to obtain the X and Y coordinates. With this raw data, we can calculate the line spread by using a histogram with set bins, and then perform a cumulative distribution function calculation to obtain a curve similar to the edge spread.

显微镜光学成像系统设计案例分享

Hi Steven,感谢您阅读我们的post。您的矛盾点来自Exit pupil的定义方式。首先出瞳是STOP经过它后面的光学系统后所成的像，其次exit pupil是近轴计算参数，用到无穷远处轴上平行入射的光 （的傍轴光线）来计算这一近轴量。下面我将把出瞳面在布局图中可视，并且计算几根真实光线帮助您理解Exit pupil的定义。在原系统中添加两个表面（surf8+surf9），表面面8厚度定义为Pupil position 求解，表面9厚度拾取表面8，scale= -1。这样在布局图中表面9就是出瞳面。   在merit funtion中添加两根主光线，计算两根特定光线在出瞳面上的高度。其中视场设置了非常少量的偏移，返回这两根光线Y坐标的差值（数值特别小代表高度相同）。如下图所示。这里是为了展示，出瞳的位置上这两根光线正好相交（即这两根光线相交处的Z位置就是出瞳位置）。但实际的软件的运算可能包含更多跟光线的检查。   两点说明：这里用了px=py=0， 见帮助手册中提到如果主光线不能追迹会采取其他方法。因此操作数1和操作数2用了主光线。 用到的是REAY，这个操作数是真实光线追迹的结果，REAY搭配Hy=±0.00001 即傍轴光线的概念。 希望以上内容对您有帮助。Thanks,Julia

ZPLM tricks that you may don't know, but can be incredibly useful

Example5: Question: POPD operands use different Initial beam/ Fiber Data settings in POP analysis setting window, how to make my POPDs use different POP setting window configurations.There are three different CFG paths. First, I will describe the differences between the CFG files.1. The CFG file with the same name as the file path2. The CFG file in the ZEMAX data path (OpticStudio.CFG)3. The POP CFG file in the ZEMAX data path (POP.CFG)It's important to note that MODIFYSETTINGS can modify the contents of paths 1 and 3, but not path 2. The POP analysis window uses the configuration file in path 3, while the POPD operation in the MF uses the configuration file in path 2.To modify the OpticStudio.cfg in the Zemax data path for the following POPD operand, we need to seek help from ZPLM, which is a user-defined merit operand. Within the merit operand, we can copy the required cfg file that has already been saved/modified and paste it as the configuration file that POPD will use.

Example 4: Question: Determine the corresponding focus shift positions for the maximum MTF value from through-focus MTF analysis, for both tangential and sagittal directions. Extract these positions/MTF values in the merit function operand format to be added in MFE.Solution: There are no built-in operands available to extract the value. However, you can create a user-defined ZPLM operand. First, create a normal macro code to report and print the values of interest. To extract values from the text report of an FFT through Focus MTF analysis window, you need to first open the analysis window and switch to the TEXT tab.Open the "FFT Through Focus MTF" analysis window. I’m going to extract data from this window, which is window number 4.

Trick: Alternative Use of TOLR - how to add an optimized parameter as an operand to the Merit Function Editor

Hi Mark,Thank you for the reply! I may have given an inappropriate example, but the concept here is that when a user wants to use user defined operand that requires another optimization process, ZPLM is no longer applicable. ZPLM can extract certain parameters that are not native operands, but it cannot perform the optimization process. This is a way to solve the problem from a user:  one of his optimization goals is to reduce astigmatism while considering the adjustable back length for his lens system, here an operand is introduced through TOLR to reduce the system's through-focus astigmatism.Julia

ZPLM tricks that you may don't know, but can be incredibly useful

Example 2: Question and workaround: How can we evaluate the results of the paraxial Gaussian analysis of an optical system and obtain a 1-D curve of beam size vs M square at the image surface? The beam size can be evaluated by using the operand GBPS, but the built-in 1D universal plot cannot make M square an independent X value. One solution is to use ZPLM to change the M square input for GBPS and take advantage of the universal plot at the same time.Example: In the attached file, ZPL06.ZPL can change the input parameter 7 (M square) for GBPS for MFE operand2. ZPLM is added before GBPS, and the weight for GBPS is set to 1 to make the reported merit function value equal to the GBPS value. With these settings, the analysis window shows the paraxial beam width vs M square.

请问如何让序列模式下的元件和非序列模式下的光源进行互动？

Hi TMX，您好。感谢在Zemax 社区进行提问。这个主题非常有趣。首先是回答您所设想的第二个方法，很遗憾答案是No。正如您所做的一些尝试。 虽然一些系统是可以混合使用序列和非序列。但前提是从序列模式Object发出的光线必定要回到序列的Image plane，同样在非序列中定义的光源无法与序列中的表面交互，序列中从视场定义所发出的光线无法被非序列Detector 捕获。再来查看一下grid phase，其背后作用的原理是人为的给某个位置的光线加入相位，所加入的相位会使光线偏转：如果是单纯的查看几何光线的话，即使我们将grid phase 转变成 grid sag, 也无法看得到预期的结果。但如果考察的是电场的传播或者波前的传播的话，理论上会有不一样的效果。这一点再下面的链接中有讨论，这里我想说的波或电场的传播对应到POP/Huygens PSF. https://support.zemax.com/hc/en-us/articles/1500005491181-How-to-design-DOE-lens-or-metalens-in-OpticStudio这也回答了您的第一个问题，我认为直接转换为矢高的方式在非序列中进行模拟是行不通的。如果我们参考非序列中自定义物体 DiffractionGrating （与序列表面的phase表达式类似）的话，可以知道是能够通过自定义的方式去进行转化。这需要一些编程的工作以及熟悉OpticStudio所开放的数据类型。 我能想到的转换方法是，用Grid Sag去替代grid phase表面，但必须达到的效果是光线经过grid sag后的行为与之前通过grid phase是一致的。您可以尝试先在序列模式中，将一个grid phase表面替换为grid sag lens 且必须设置折射率，否则没有光线偏转效果，然后再像面上查看替换前和替换后要有相同效果。如果这种转换可以实现，再将同样的Grid sag lens设置搬运到非序列中使用。我查看了下您的phse profile, 不确定这种方法是否可行。另外您提到的文章，我阅读后如有可添加的信息，再来更新。另外附加一篇相关文章： https://optics.ansys.com/hc/en-us/articles/360042097313-Metalens感谢~  Julia

如何用zos-api，將IncidentAnglevsImageHeight的分析數據結果輸出為CSV並繪製成圖表

Hi HC,我在您的最新帖子中回复了您的问题。您所考察的这个分析不可以直接借用范例4完成。是因为ZOS-API的接口对于各个分析所支持的输出形式不一样。比如FFTMTF分析，支持通过GetSettings()后access其中的各个设置参数（如波长）的方式去更改设置,数据可直接获取。但IncidentAnglevsImageHeight既不支持setting的设置 也不支持 data的输出。对于没有开放直接更改设置的一些分析，如上图中 IncidentAnglevsImageHeight setting显示False, 可以可用MODIFYSETTINGS方式更改。参照范例中的code: 希望以上信息有帮助。Julia

ZPLM tricks that you may don't know, but can be incredibly useful

Example1 : Through focus spot diagram/Through focus MTF is the handy tool that can be used in imaging system analysis to quickly assess the performance of an imaging system as the image plane moves back and forth. MTF (Modulation Transfer Function) is a measure of the ability of an imaging system to transfer contrast at different spatial frequencies from the object to the image, and it is often used as a measure of system resolution. The lower the MTF, the less resolution the system can obtain at specific frequencies. In other words, if a lower MTF value is used as the limitation of human perception of sharpness, the corresponding frequency can be calculated when the image plane is moved at that specific MTF value. In the example below, MTF=0.2 is the threshold metric used for the evaluation.Two macros are defined: ZPL06.ZPL Through Focus Frequency.ZPL ZPL06.zpl is a macro that can be added to the Merit function editor as ZPLM. The purpose of this macro is to transfer a (dummy)paramete

在照明模式中，建立彩色遮色片。

可以的，您应该是在非序列模式中进行的操作。可使用非序列中的物体——Slide 物体。在光线发出后不远的位置放置Slide物体，添加物体后，软件会要求用户在指定文件里选一张图片作为这个物体加载的图像。效果就类似在投影机中放一个幻灯片。图片放置的路径：C:\Users\...\Documents\Zemax\IMAFiles要注意的是，想要查看成像效果，光源需要会聚，因此在系统中或者使用真实的聚焦透镜，或者使用近轴透镜，将光线会聚到探测器物体上方可成像。可以参考下面的范例文件：C:\Users\...\Documents\Zemax\Samples\Non-sequential\Sources\Slide sample.ZMX请查看光源物体的波长/光谱设置：利用三刺激值定义的白光光谱分布。下面，我进行如下更改，代表将使用系统波长定义，并且指定光源物体1的波长是系统选项中的波长编号1.再来运行光线追迹，我们看下会是什么结果：探测器上显示的真彩图确实是按照如上设置进行追迹后的结果。

Zernike standard sag 表面的 Norm radius 如何理解？

OpticStudio中有一些表面定义的时候使用了归一化半径。而非使用原本的位置坐标。即不使用 Z= f (x,y) 或 Z= f (r)的方式来定义，我在这里提到的 r 是表面为旋转对称的情形 r = srqt(x*x+y*y)。 对于使用归一化半径的那些表面，大多数sag的表达式在系数表示方面用的是 Z= f(ρ) 。这里的可以是 ρ= x/Norm radius, 或 ρ= y/Norm radius 或  ρ= r/Norm radius. 归一化半径是没有量纲的。为方便，下面利用扩展多项式表面做说明： 假设当前表面中设置的归一化半径的值为 M ，那么根据参数14的说明， 我们把多项式的前几项写出来（eg: X1Y0代表 X的一次方Y的0次方）：如果，归一化半径从M变为1，同时不改变 Ze （上图当中上下两个Ze表达式一致），系数的变更如下：Norm Radius 1st 系数 2nd 系数 3rd 系数 4th系数 5th系数 6th系数 M A1 A2 A3 A4 A5 A6 1 A1/M A2/M A3/M/M A4/M/M A5/M/M A5/M/M/M  —————————————————————————————————————————————再回到问题本身，对于Zernike Standard Sag 表面，要做相应的变换，我们需要先查看下描述表面使用的多项式。可以看到矢高的描述是通过 Z=f(ρ，φ)，自变量类似于极坐标系。其中的ρ是径向归一化坐标。假设N是设置的归一化半径，那么（r,θ）处的归一化坐标ρ = r/N, 其中 r = srqt(x*x+y*y) 。如果把上面的式子展开，Zz= A1*Term1 + A2*Term2+ A3*Term3+ A4*Term4+….与上面讨论的扩展多项式类似的。但如果按照上面的思路来进行系数的换算的话，观察Z4项/Z11，就会发现，对于包含了有常数项的 Zernike项，还要复原参数带来的常数项影响。用一个例子来说明针对Zernike Standard Sag 更改Norm radius 如果通过更改系数来维持表面矢高不变。为简单起见，我们仅使用Zernike项到第5项。 假设我们有一个表面，初始的归一化半径设定为10，现在
