If no previous settings have been saved for this or any other lens, then the default settings used are the “factory” defaults used by Zemax. If no lens specific default settings exist, then the default settings for all Zemax files, stored in the file “Zemax.CFG” will be used, if any. If the lens file has its own default settings, then those will be used these are the settings stored in the “lensfilename.cfg” file. If the flag value is 0, then the default settings will be used. The settingsfilename$ argument is a string for using or saving the settings, depending on the value of the flag parameter. If no type is provided or recognized, a standard ray trace will be generated. A list of string codes may be found on the “Buttons” tab of the File, Preferences dialog box. The string codes are identical to those used for the button bar in Zemax.

#ZEMAX 16 CRA CODE#
The type argument is a 3 character string code that indicates the type of analysis to be performed, as shown in table 3.9-1. The string function $TEMPFILENAME can be used to define a suitable temporary file name.

The textfilename argument is a string for the target file name, including the full path and extension of the file name. The syntax is GETTEXTFILE textfilename$, type, settingsfilename$, flag 3.9-1: ZEMAX analysis options and different output of the resultįor the text output, ZPL provided a keyword GETTEXTFILE to read related information and store the result in a text file. (b) graphical output of the analysis resultįig. In this example we assume the optical system is the doublet defined in example ex30401.ZPL. For example, the menu option Wavefront Map in figure 3.9-1(a) can display the wavefront map at a given surface, as shown in figure 3.9-1(b), as well as text information of the wavefront map shown in figure 3.9-1(c). Zemax provided a lot of analysis tools to evaluate the performance of an optical system, with many of them providing text output. You don’t need to read it from beginning to end, but when you need it, it’s handy. It is demonstrated that heterodyning (i) improves the dynamic range substantially even if the radiation from the local oscillator is distributed over the camera area, and (ii) allows sensitive determination of object-induced phase changes, which promises the realization of coherent imaging systems.You can now purchase a paperback version of this book from Amazon:įor a beginner who wants to master the tool of ZPL, this is a good tutorial to make your learning process less stressful and more fun.Įven if you are an experienced Zemax user, it is still a good idea to keep this book as a reference. Imaging examples acquired in direct and heterodyne detection mode, and in transmission and reflection geometry, show the potential for real-time operation. Using detectors with a noise-equivalent power of 43 pW/☒Hz, a distributed illumination of 432 μW at 591.4 GHz, and an integration time of 20 ms (for a possible frame rate of 17 fps), this virtual camera allows to obtain images with a dynamic range of at least 20 dB and a resolution approaching the diffraction limit. A 100×100-pixel camera with an active area of 20×20 mm² is physically simulated by scanning single detectors and groups of a few detectors in the image plane. We explore terahertz imaging with CMOS field-effect transistors exploiting their plasmonic detection capability and the advantages of CMOS technology for the fabrication of THz cameras with respect to process stability, array uniformity, ease of integration of additional functionality, scalability and cost-effectiveness.
