The layer thickness was change from operand "CODA" that constrains the coating multiplier. zemax. 6 Sub-Function. Classical definition of the merit function in Zemax: Special merit function options: individual operands can be composed: - sum, diff, prod, divi, of lines, which have a zero weight itself - mathematical functions sin, sqrt, max . The goal for the optical design is to find the systems achieving the best performance within some boundaries. • Kreuzer, US patent 3,476,463, 1969: “Coherent light optical system yielding an output beam of desired intensity distribution at a desired equi-phase surface. Zemax 13 delivers state-of-the-art design, simulation and optimization capabilities plus breakthrough features that reduce time-to-innovation Zemax can also model the effect of optical coatings on the surfaces of components. I understand the part that you restrict the image height w. 125π) were traced towards the ‘observer’, which is defined as a surface with a 10-mm clear diameter. ZEMAX removes all of the variables (but not the solves) The tolerance operators are read and the compensator(s) are set as variables. We can simplify this a bit to Where j and k run over all surfaces. • ZEMAX and the beam shaping merit function were used with global optimization to design 2-plano-aspheric beam shaper as feasibility test. Table 8: ZEMAX merit function specifications used to jointly optimize d2  Sequential modes of ZEMAX http://www. Only these can be used in optiSLang for further analysis. Dec 16, 2015 · Then the merit function is Where is the weight on the MNCA operand, is the sum of all the other merit function operands with nonzero weight and is the weight of all the other operands. Therefore the system must be diffraction limited d) The numerical aperture is changed to NA = 0. The TRAR operand, when listed in the Merit Function Editor, causes a: single ray to be traced whose aberration value is returned in the "value" column. 3 Function. 16 Nov 2017 the same location as the MTF merit function. Since the merit function of the centennial lens is not the optical invariant, I tried to break this correlation to simplify the system. ) following section of the ZEMAX User's Guide: “Chapter 6: System Menu > General > Aperture. ZEMAX is the easist program to use though some of their user support staff is less than nominal (you know who I am talking about) and some of their algorithms need work. Saissea aLaboratoire d’Astrophysique de Marseille, Site des Olives BP8-13376, Marseille, France Abstract A slicer mirror is a complex surface composed by many tilted and decentered mirrors sub-surfaces. If the filename contains the complete path, then the specified file will be loaded. The keys may then be checked back in to the appropriate server separately, as desired. The rms spot size was chosen as the value to be optimized. Zemax interface, menus, file handling, system description, editors, preferences, algorithms, merit function, variables, pick up's. ZPL, and the merit function is set as in program ex30501. This can help optical designers get to a high-confidence digital detector design, faster. Sensitivity Analysis Is anyone familiar with this type of F-theta lens? I have one question about the constraint you put in the merit function. No. 但由於Merit Function是計算 “差值” 的方均根,因此最後的Criterion事實上是取(1 - Merit Function Value)。 這個部份請看下一個條目的說明。 Criterion的部分如果系統內建預設的選項不足以滿足使用需求時,使用者可以考慮自行設計Merit Function,然後在Criterion的欄位中選擇 在Zemax OpticStudio中,要打開MFE,可從主功能表上選擇Optimize > Automatic Optimization> Merit Function Editor。 評價函數是從數字方面描述一個光學系統滿足特定目標的程度的函數。在MFE中,Zemax OpticStudio會給出一個操作數清單,它們分別代表系統的約束條件或目標。 SPIE 7652, 6522S (2010). In many cases, the macro may need input information that would be obtained from one of the many merit function opera The NSC Optimization Wizard provides a quick way to create a merit function composed of any number of these typical targets. 7 I/O and File Operation Dec 14, 2015 · Faster Optimization for Classic Lens Designs (All Editions) – a new merit function wizard in OpticStudio 15. Tool:ZEMAX • What is ZEMAX? `ZEMAX is a program which can model, analyze and assist in the design of optical systems, but is NO substitute for good engineering practices´ • What do we do with ZEMAX? • Plug in an optical design (lenses, THz:mirrors) • Ray tracing as first check (focal point @right positions) • PHYSICAL OPTICS PROPAGATION Has anyone wrote his/her own client for communicating with Zemax? Not using standard one provided with Zemax Corp. CreateSolveType(ZOSAPI. zGetRefresh () to copy the lens from the LDE to the DDE server. The merit function value is the measure of the effectiveness of the optimization method. 5 Jun 2014 Introduction. Our primary goal is the comprehensive success of our customers. MaterialCell. By harnessing the power of OpticStudio®, OpticsBuilder™, and OpticsViewer™, optical, mechanical, and manufacturing engineers can speak the same language across the optical product development process. In the course of the work, we found that the merit function used in the Integration of VirtualLab 3 Zemax parametrization • Define all outputs of the system in Merit Function Editor. Default Merit Functions There are about a little over 20 different default merit functions that can be defined in Zemax. It is a numerical value defined by the user and used to evaluate the deviation of an optical system performance relative to a series of design targets. 28 Aug 2012 Tutorial Zemax 4 Optimization. Zemax Knowledge Base gives a design method to convert Gaussian irradiance profile to flat top profile (see reference [1]). Harness the power of Zemax software. Merit Function . Then we can get the displacement Δ ( D o ( m ) , W ( n ) , r ( i ) ) , which is introduced by these rays relative to the chief ray at the image plane. construct a beam shaping merit function. The exact result depends on the Figure 3 shows the Zemax merit function editor. Optical Design Program. code skills will include prescription entry, variable selection, merit function. The goal of the optimization is to reduce the merit function value. Feb 27, 2015 · When using Zemax to design and optimize an optical system, merit function is often used. 5 Flow Control. If the use of a standard merit function leads to an unsatisfactory result poor local minimum or stagnation , switching between the new and the standard merit function can lead to escape. Congratulations on your purchase of Zemax OpticStudio! Automatic Optimization provides access to the Merit Function Editor, which is how a system's. The starting designs for both lenses were based on the Ge–ZnSe–Ge, and the Si–Ge–Si air-spaced triplet designs described in Laikin's book (chapter 3: The Air-Spaced Triplet) [1]. with Zemax Technical Support Our technical support team is here to get you the answers you need and keep your engineering teams up and running. Dec 16, 2015 · After this, the Merit Function will look like this Local Optimization Now let’s access the properties and methods for running a Local Optimization and set it up like in the Graphical User Interface. zemax merit function
