Is there a way to tolerance irregularity on a 'Binary 2' surface type?

when i use POP to calculate coupiing efficency.  Find polarizate transmission wrong in coating . below is my transmission table: in surface 7 , coating is i.99 but in transmission it is 1.00794. I think it must be wrong in Zemax.   perture, Fresnel, coating, vignetting, and internal transmittance effects are considered.

Here's the discussion space for the OpticsTalk: Flash LiDAR in new iPad Pro and its Modelling, to hosted by Zemax Senior Optical Engineer, Sandrine Auriol. Apple introduced flash LiDAR in the new iPad Pro for AR applications. Join Sandrine in this talk to discuss the principle of flash LiDAR and methods of modeling it in OpticStudio. Stay tuned on this forum thread for updates and discussion after the talk!

Hi there, I have created a standard beam splitting cube in non-sequential mode using two Prism90 polygons, with surface coatings of I.99 and I.50. I am now interested in making a polarizing beam splitter. What is the best way to go about this in a non-sequential mode? Thank you so much! 

It's suggested to see also see forum post:  Sometimes users are confused why the 'Remove Vignetting Factors' option in the analysis Relative Illumination is by default checked on. Also some may wonder why the operand RELI always removes the vignetting factors. In this post, let's discuss and explain why it's usually not a good idea to use vignetting factor when evaluating the system's RI or MTF.         To explain, let's open an example and examine what happens if we turn on and off the vignetting factors.   1. Open '\Documents\Zemax\Samples\Sequential\Objectives\Double Gauss 28 degree field.zmx'  2. Run 'Design Lockdown' to fix the sysetm before we start evaluations.    3. Let's check Footprint Diagram on STOP (surface 6) with Wavelength = 2 and Field = 2. For now, as expected, the beam can fulfill the STOP.    4. Now let's make the final surface's aperture smaller as below.    5. As expected, the Footprint Diagram changes as below.    6. Here is how the smaller aperture changes Layou

When we run a tolerance analysis, in the report, there is always a section for 'Estimated Performance Changes based upon Roo-Sum-Square method'. Here let's give an simple math to explain why this can be considered as 'worst case' in tolerance. In Help file, we can explanations as shown below. Normally, this value can be considered as the criterion of the worst case of the system after consider tolerance. If the RSS performance is acceptable, then it's very likely the final really-fabricated system can meet designer's goal.   Here we will use the 'Stack Up' question to explain the calculation of RSS.   Stack Up question Here is the question: Imagine we have 5 wood plate to be stacked up together and we would like to estimate the total thickness of the the stack. We already know each wood plate has different thickness (which is error!). The thickness of each plate is 25 with an error of +-0.1 mm. Assuming the probability of thickness of a randomly-t

It seems like there are a few different ways to model a Gaussian in OpticStudio. What way is best?

On the multi-configuration editor, there is a special solve called a thermal pickup. This pickup solve is used to compute a new value for a multi-configuration parameter based up on the temperature and pressure of the new configuration as compared to the 'reference' configuration. Thermal pickup solves only affect data for certain types of multi-configuration values. The thermal expansion and contraction is assumed to be isotropic, thus the linear dimensions change equally in all directions. Therefore, a solid glass sphere is still a sphere after being heated or cooled. In the same manner, a parabolic surface , with conic of -1, will still be parabolic after any temperature change and thus the conic constant is temperature invariant. This makes sense since the conic constant is a unit-less quantity.

I need to constrain the output diameter of the CPC object. However this parameter is not available in the parameters. Do you have a work around for that?

I'm finding the max and min slopes on a surface as reported by DSLP to be confusing. A spherical surface with high slopes is reporting a maximum of zero. And a Tilted surface, which is just a plane, is reporting two separate values for min and max. What am I seeing with this operand?

What is the fastest way to collimate the light coming from a point object with a lens? I would like to optimize the position of the object, such as the light after the lens and hitting the image plane is collimated. An equivalent of minimizing RMS Angular radius in sequential mode.   I reversed the optics to use the quick focus tool to find the focal distance and then reversed them again, but I wonder if there is a “quick collimation” analogue to quick focus.   I hope I explained myself ;)

I found this web page somehow while searching MyZemax, and can't find it to get there again with any searches, so I thought I would share it with everybody: https://my.zemax.com/en-US/Licensing-Policies/subscription-faq/ Note that this is NOT the same page found at (MyZemax) Home > Licensing > Subscription , and as far as I can tell, you can't find it as a tab or link within any of those pages, either: It has lots of good information on license policies in general, pricing, keys, and migration from Perpetual to Subscription versions, which I have been considering (although still don't fully understand).  I'm assuing that it's correct and that Zemax wants people to know this information! -- Greg

I am running some API code. It was working fine before, but now I am running it again and am getting the error 'Attribute Error: 'NoneType' object has no attribute 'ClearDetectors''. Why is this suddenly appearing?

Hello, I'm quite new to ZOS and I use the version 15 (yes, I know it's 5 years old but the upgrade is quite painful in my company). I wonder if I can find anywhere a synthetic log file with informations like the number of rays which where traced, the various non-blocking errors (such as geometric errors), the duration of the simulation, the amount of memory used and the like. Something like what I get with the Prescription Data button but with outpu data and not input data.   Regards

Is there a way to include minimum increment values to the compensator when performing tolerancing analysis, such that the compensator can only have a discrete number of values equally spaced within its range? I would like to simulate what effect the displacement resolution a piezo or stepper motor has when implementing these devices as a compensator in a physical experimental setup. Thank you.

Hi,    I want to know about different types of thickness solves, what are they when and how to use these solves? I request all to kindly suggest the reading material or any article related to it. Thanks,

Hi all,   I am trying to desing an imaging imaging lens for single color, 19:16,  microdisplay. Got good enough mtf in both geometric and FFT. However, when using the extended scene analysis>>image simulation,  it seems like the mtf is much worse(Checked against the cooke triplet, attched bellow also). I tried to change the sampling in both the pupil, psf etc. but still get blurry image.  What am I doing wrong? Many thanks, Nadav     EDIT: With only one color at the image simulation it's much better. I assume this is the problem?

Does Zemax have Panda MN218 material? I like to use this material in BS. If not, what information do we need to make a model?      

When you put a 'Substitute' solve on a material it will ask for a catalog. If you would like to pull from multiple catalogs, just leave this blank and put your catalogs of interest in your 'Catalogs to use' section of the System Explorer. 

Does anyone have experience and information of modelling optical properties of black polyacetal (black 'Delrin'), in NONsequential mode, to properly model the surface reflectance (about 5%) *AND* the bulk absorption that makes it black?

Hello! I keep getting the error message: 'Cannot compute when chief ray cannot be traced!' during optimization using least squares method. The optimization interrupts and resumes once I click 'ok' or 'X' on the message pop-up window.  Any ideas how I could interrupt at the point where the error-message pops up to investigate the cause? Are there any options to automatically ignore this message and resume the optimization without having to click the message away manually? I am using the damped least squares optimization to optimize the shape of the example UD surface 'us_multizone_asphere' with two zones. I already tried different merit function operands without success. As it did not occur with simpler surface structures, I assume that some geometric surface constraints are required. Any ideas how to approach this (e.g. setting appropiate geometry constraints...)? Thank you! Simon

Hello, I'm using one of your examples from here: https://my.zemax.com/en-US/Knowledge-Base/kb-article/?ka=KA-01355 I want to use 1550 nm as a wavelengh however, the dispersion diagram for the materials don't have data for that wavelength - graph below. Is there anyway to overcome this? Thank you, Narciso

For modeling the transmission of a system I put sensor at the input and another sensor at the output, but I get a transmission which is not compatible with measurement values (it is much lower).   For understanding what is go on, I build the following configuration:   One ray as source, which incide in a BK7 cilinder at zero degrees, and put the detectors before and after the BK7, the first detector records the 100W of the input, but the second record 91.7W  , getting 91.7% instead the 96% I expected.   Indeed, at 'Coating-Transmsision vs angle ' I see that the transmisison for the BK7 is 0.957 at zero degree ( I used 590nm wavlength).  But at the original model I need the overall  transmssion integrated over all angles.   What   I made wrong with the detectors?  There is it a more efficient form to establish the transmission of the system than my detectors aproach?  

Is it possible to somehow create an axis break in the 3D layout when working in non-sequential mode? For example, if in my layout I have a beam source that hits an object that is a very long distance away, with no other objects along this path. I want to be able to see everything in the layout without having to zoom out so much that I can't see any of the details in the layout. Is there a way to create a sort of axis break that hides a large portion of the path?

Hello, I am trying to optimize a basic four mirror ring cavity in a bowtie configuration. I am looking to optimize the system for the following traits in order of highest to lowest importance: 1. Folding angle of the mirrors to minimize distortions and abberations 2. Minimize the gaussian beam waist at a particular surface (currently set to a detector rectangle)   Additionally if possible, I would like to see how much enhancement we achieve in the cavity upon reaching the cavity's steady state behavior. The system is designed in nonsequential mode. I have set the variables, but I not sure how to correctly use the merit function editor.   How can I optimize for the two traits above, while keeping the variables within my physical constraints?   Ring resonantor image from https://www.rp-photonics.com/ring_resonators.html
