Tips to switch between different operand combinations

For example, I want to set up two different set of criteria(for example spot and wavefront) to optimize. how can I switch between these two?Method 1: Create two set of merit function combinations, then load the merit functionMethod 2: Use GOTO or ENDX to swtich (change the value of GOTO) You can find more interesting operands here, please enjoy:The Optimize Tab (sequential ui mode) > Automatic Optimization Group > Merit Function Editor (automatic optimization group) > Optimization Operands by Category > Merit Function Control Operands Another example is BLNK, you can comment and this helps to locate the operands group easily.

Envision 2020 Workshop: Coordinate Breaks

This forum thread should be used to continue the discussion from the Envision 2020 workshop, Coordinate Breaks. Presenter: Angel Morales Abstract: Coordinate Breaks are instrumental when modeling off-axis and other non-rotationally symmetric systems. However, specifying parameters like arbitrary pivot points in 3D space is non-trivial in a sequential coordinate system. In this session, we'll take a closer look at setting up Coordinate Break surfaces and utilizing functions like the Coordinate Return and different Solve types to more efficiently set up complex systems.

Listing the Q-con Polynomials

Generating the Q­con polynomialsOpticStudio supports Q-type aspheres.  Type 0 indicates Qbfs polynomials, and Type 1 indicates Qcon polynomials.  The functional forms of the Q-type polynomials are fairly complex due to the requirement that the polynomials be orthonormal for a circular aperture.  Occasionally, it is convenient to know the functional form of the polynomials for testing and comparison purposes. Below, we list the first 20 Qcon polynomials, and also share the derivation in the Mathematica file GenerateQConPolynomials.nb.  The .nb files for Mathematica can be used by downloading the free Wolfram Player: https://www.wolfram.com/player/.Important equations for the Qcon polynomialsThe Qcon polynomials can be calculated in a straightforward way using an equation for the Jacobi polynomials.From Shape specification for axially symmetric optical surfaces, G.W. Forbes, Optics Express 5218, Vol. 15, No. 8, 16 Apr 2007, the polynomials are related to the Jacobi by:Definitions for the

Analyticals change with thermal results and differing license levels. Why?

This is a situation that may arise for users with a Standard license if you are collaborating with colleagues using a Professional or Premium license. Each license level has an increasing set of features and abilities, and one of these is that the higher two levels support the use of Mechanical Semi-Diameters (MSD) and Chip Zones. These allow the user to account for mechanical mounting by extending the surface area beyond the optically used region, either by extending the surface shape or by protruding a flat extension around the edges beyond the Clear Semi-Diameter (CSD). The purpose of these options is to more easily account for mechanical issues when designing a system. In optical terms, these have no direct effect. They do, however, have an indirect but measurable effect when performing thermal analysis because they directly affect the changes made with temperature.Users familiar with the Make Thermal tool will recall that thicknesses, curvatures, and other mechanical parameters ch

Creating Thin Film Tapers

I want to share this because I wasnt able to find any information on it in my original searches and the help is a little confusing on the requirements. I’ll use the PT (polynomial) taper as an example since its what I used.To start with, an important element to remember is that anything in the coating has to come before it in the coating.dat file-so both the TAPR and the MATE have to be before the COAT to function properly.  For each PT line, the first element is the order (x^2, x^1, etc) and the second the coefficient. As such, order zero defaults to 1, so it can be excluded here, but knowing its one is important for understanding how to generate coefficients. My initial error was that the coefficients (C2, C1, C0) where as follows, with a thickness d and a position x (in this case, looking at a single axis):C2*x^2 +C1*x +C0=d(x)However, this is inexact. For TAPR coefficient (g2, g1, g0) its more accurately the following:d(0) * (g2*x^2 + g1*x+g0)=d(x)To compare with the previous formu

Hello Community!

Hi Everyone!My name is Jordan Teich and I am working from Boston as an Optical Engineer on the Zemax Customer Success team.  I only just joined the team in early 2021, but I’ve had a great experience here so far! Before joining Zemax, I received my B.S. in Optical Engineering at the University of Rochester.  After graduating, I worked as an Optical Test Engineer in the aerospace industry for ~4.5 years.  It was a fast-paced environment where I was able to run optical tests for a number of interesting space payloads and sub-assemblies! I loved getting the chance to work with cutting edge space products.Besides working, I love spending time outside playing tennis, hiking any nearby mountains, or exploring new areas on my bike.  You will also often find me watching older movies that are playing at one of the repertory theatres in the Boston area.  Looking forward to talking with you all on the new forums!

Example of a Thermal Index Data file (*.TID)

I have attached an example of a TID file. This file contains the index of refraction at multiple temperatures and wavelengths. The first line contains the word PRESSURE followed by the ambient air pressure in atmospheres.Then the data consists of 3 columns: temperature, wavelength, and index.The temperature of the first data point defines the reference temperature for the glass.It can then be fitted with the Glass Fitting tool.Once you run the tool, you will get a report and this can be automatically added to a catalog.

Modeling and Mitigating Surface Aberrations and Irregularities through Using Composite Surfaces

One of the many uses of OpticStudio composite surfaces is that they offer a powerful tool to analyze and manipulate optical surface irregularities. They enable the addition of multiple sag profiles to create complex surface distributions. Therefore, users can stack multiple surfaces to study various optical effects. To demonstrate this usage, we will use an achromat lens with composite surfaces configured through the multi-configuration editor.  One of the critical elements in this approach is the correct utilization of the Zernike fringe sag surface type on the add-on composite surface. This surface choice allows us to convert Seidel aberrations from Zernike expansion coefficient terms. Consequently, by manipulating the parameters on this surface within the multi-configuration editor, we can effectively manage the Seidel aberrations arising from the surface irregularity. As a designer, one can follow this step-by-step guide to analyze, model, and mitigate surface aberrations and irreg

Material of same name in two different active catalogs

QUESTION: I have two catalogs in my “Catalogs To Use” section of the System Explorer. Both catalogs have a material named “Glass1” in them, but it is defined differently in each catalog. Which catalog will it draw from if I use “Glass1” in my Lens Data Editor? ANSWER: If there are materials of the same name in multiple catalogs, OpticStudio will use the material from the catalog that is higher on the “Catalogs to Use” list. As an example, imagine the material “Glass1” is in both the SCHOTT and ALOHA catalogs. If it is used in the LDE, it will be pulled from the SCHOTT catalog because it is defined above ALOHA.
