Hi guys, I’d like to use this post to introduce myself! I’m with the Zemax Customer Success team and help our customers with their technical inquiries on our software. I’ve been with the team for 3 and half years now and am loving every part of the job! I got my PhD in Physical from U of R and before joining Zemax I worked at GigOptix Inc for about 10 years on developing high speed electro optic polymer modulators. I love working with lasers!I hope to see everyone here often in the new forum and let’s chat OpticStudio! :)
Reverse a HUD system
This post provides a potentially working method for reversing an off-axial sysetm such like a HUD. It may not work with all systems, but have been proved to be useful for some systems.Turn off RA. Clear all fields. This is becuase RA will throw erorrs during the following tweaking. And the field data is unlikely to be unchnaged so let's just remove it and re-add them later. If the number of mirrors is odd, add one more mirror after object, using the Add Mirror Tool. Add a dummy surface after object and before image. Select all surface and reverse. After reversing it, multiply all decenter/tilt by -1 and set Order flag to opposite. Remember to adjust image and object distance. and turn on the RA again. You can remove the dummy mirror if you add it at step 2.In the attached video, we showed an example of using this process with the following example in the KBA. Note in the video, I forgot to do the final step to turn on the Ray Aiming.https://support.zemax.com/hc/en-us/articles/150000557
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!

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.
I’d like to go ahead and introduce myself briefly. I joined Zemax in January of 2019 as an Optical Engineer working on OpticStudio support. Prior to that I have worked for Boeing and for the European Southern Observatory headquarters as well as some other educational forays into the intellectual worlds of sciences and humanities. My educational background is primarily from Rensselaer Polytechnic Institute and the University of New Mexico, heavily emphasizing optical physics.Besides work, I enjoy various RPGs and board games, reading about history, and watching too much Star Wars and Star Trek.
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

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.
How to add more lines to the Fit Index Data tool
QUESTION: how do I add more than 3 lines to the Fit Index Data tool in the Materials Catalog? ANSWER: Press Insert on your keyboard to insert more lines into the Fit Index Data editor. Also, if you have the data in a text format similar to the one shown below, it can be saved as a .DAT file and can be loaded in with the “Load Index Data” button.

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.
Envision 2020 Workshop: Designing for Manufacturability
This forum thread should be used to continue the discussion from the Envision 2020 workshop, Designing for Manufacturability. Presenter: Katsumoto Ikeda Abstract: Careless approaches to optical design can result in designs that are sensitive to manufacturing and alignment errors, resulting in optical products that are difficult to manufacture successfully repeatedly. Methods for desensitizing the optical system, including and High-Yield Optimization, produce designs that meet tight performance specifications, provide a higher manufacturing yield, and lower manufacturing costs through less waste. Join our workshop to discover our best practices in using these methods. You can also find the Envision 2020 LinkedIn group here.
