1、zemax非顺序系设计教程如何创建一个简单的非顺序系统 Setting up Basic System Properties建立基本系统属性 We will create a non-sequential system with afilament source, a parabolic reflector and a plano-convex lens that couples light into a rectangular lightpipe, as shown in thelayout below.我们将创造出一个带点光源的非序列系统，抛物面反射镜和一个平凸透镜镜头耦合成一个长方形光管

2、灯，如下面的布局显示。 We will also trace analysis rays to the detectors to obtain the irradiance distribution at various points in the optical system.我们还将跟踪分析射线探测器获得光学系统中的各点照度分布。 Here is what we will finally produce:下面是我们最终将产生： If ZEMAX is not running, please start it now.如果ZEMAX软件没有运行，启动它。 By default, ZEMAX

3、starts in sequential/mixed mode.默认情况下，ZEMAX软件启动顺序/混合模式。 To switch to pure non-sequential mode, open ZEMAX and click FileNon Sequential Mode.要切换到纯非连续模式，运行ZEMAX软件，然后点击文件“非序列模式。 Once in pure non-sequential mode, the window title bar of the editor will display the Non-Sequential Component Editor instead

4、 of the Lens Data Editor when in sequential mode.一旦纯非连续模式，在编辑器窗口的标题栏将显示非连续组件编辑器而不是在连续模式时只用于连续或混合模式系统的镜头数据编辑。 The Lens Data Editoris usedonlyin sequential or mixed-mode systems. For this exercise, we will set the system wavelength, specified under SystemWavelengths, to 0.587 m.对于本练习，我们会设置系统波长，点击系统波长，

5、指定波长0.587微米。 We will also set the units under SystemGeneral Unit tab as follows (default).我们还将在系统设置单位，SystemGeneral /Unit tab “一般组标签如下（默认）(default).。 In addition to radiometric irradiance unit such as Watt.cm -2 , you can specify photometric and energy units such as lumen.cm -2 or joule.cm -2 .除除辐射辐

21、sparent since the material type is air (blank in the editor).该探测器完全透明的，因为这种探测器材料是空气（编辑器中的探测器材料空白）。 跟踪分析射线的探测器 To see theoptical intensity at thedetector, we need to open the Detector Viewer by clicking Analysis Detectors Detector Viewer.要看到在探测器的光强，我们需要通过点击分析探测器检测器查看器（Analysis Detectors Detector View

22、er）。 You will notice that the detector viewer is blank with zero total power, even though we see rays reaching the detector in the layout.你会发现，探测器查看器总功率为零的空白，即使我们看到射线已经到达探测器。 The reason is because the rays are traced separately for the layout and for the detector viewer.原因是因为布局和探测器探测器的光线追踪是分开的。 We n

23、eed to trace the analysis rays to the detector first to see the result.我们需要跟踪分析光线（# Analysis Rays）到探测器上以得到结果。The number of rays traced to the detector is specified in the “# Analysis Rays” parameter column of the Source Filament object in the editor, which is usually a large number: 5 millionin this

24、 case. Remember, layout rays do not affect the Detector Viewer results; only analysis rays do .该追溯到探测器中的射线数在线光源编辑器中参数列“分析的射线”（ “# Analysis Rays）被指定，这通常是一个很大的数字：在这种情况下500.00万。 记住，布局射线不影响探测器浏览器的结果，只有分析射线才影响 。 To traceanalysis rays to thedetector, open the Detector Control window under AnalysisDetector

25、sRay Trace / Detector Control.要追迹分析射线（“# Analysis Rays）到探测器，打开探测器控制窗口下的分析 “探测器”光线跟踪/检测器控制。（AnalysisDetectorsRay Trace / Detector Control） Always remember to the clear the detector bypressing the Clear Detector button, if you do not wish to add the result from the previous trace to the current one.永远

26、记住按清除检测按钮清除探测器，如果你不希望添加从以前的跟踪结果到下一次追迹。 Press Clear Detectors then Trace button followed by Exit.按清除探测器然后追迹按钮然后退出。 The detector viewer will display the irradiance distribution, revealing the hotspots caused by the filament source.该探测器浏览器将显示辐射分布，展示了丝源造成的热点。 Ifyour Detector Viewer looks different, open

27、 the detector viewer settings window and make sure the settings are as follows.如果你的检测器样子不同，打开检测器设置窗口，并确保设置如下。 You can also see the detector trace result in the NSC Shaded Model Layout by selecting “Color pixels by last analysis” option in the settings.您还可以在NSC阴影示范布局中通过选择“最后的分析颜色的像素”（ Color pixels by

28、 last analysis）中的设置选项看到检测微量选择，在的结果。 添加普莱诺凸透镜 Now that we have a source and a reflector, we will add a refractive plano-convex lens 10mm to the right (+Z) of the detector. Insert a line after Detector Rect in the editor and make the type Standard Lens with the following parameter values.现在，我们有一个光源和反射
