ZEMAX file to Code V file conversion

Hi, I would like to convert a ZEMAX file to Code V.  However, when I use the zemaxtocv.seq Macro in Code V, I get this message there: ... The file may be in Unicode format, convert to ANSI and try again How can I convert a ZEMAX fie format from Unicode to ANSI?  (I should add that my Zemax file has a Non-Sequential component) Thanks for your help.

Measure focal length of a lens

I am using a Zemax model of an Edmund Optics lens in my design. The lens has a focal point of 10mm at 587.6nm, but my instrument will use a 650nm laser. Is there a tool in Zemax that calculates the focal length of a lens, with consideration of wavelength? Alternatively, I would appreciate guidance on how to calculate this by hand. The best I have been able to do so far is eyeball the location where the light converges and measure that distance (which appears so be about 12.3 mm).

migration from perpetual to subscription licence

Hello, I became aware a few months ago that Zemax had decided to introduce subscription licencing (i.e. software leasing rather than software purchase), which changes radically (and IMHO not positively) the nature of the relationship between Zemax and its customers. As my single user private perpetual licence support is about to expire, I have asked for a quotation for support renewal. Not only that the support renewal price went up by 20% over last year (which pushes me well over the limit of what I can afford to fork out for licence support every year in exchange for, judging by the experience of past updates, little more than cosmetic changes and minor bug fixes), but I was also told that I am strongly encouraged to transition to an even more expensive subscription licence, which apparently will include access to more technical innovation in the OpticStudio updates than offered by the perpetual licence. I have a few related questions:   1) what exactly in terms of software u

Rays avoiding an object to speed up raytrace and reduce rays needed

Hey all, A model I am working with is composed of a source ellipse, a 500mm lens tube and an aspheric lens used to focus rays from the source ellipse onto a detector. All of this is using the non-sequential mode. I am finding that when I set a ray amount (1e7)  the raytrace takes some time and very few of the rays are actually making it to my focal plane, and the resulting image drawn is very sparse with not nearly the amount of data that I am looking for. My question is:  Because the object is 500mm away from my input aperture (the aspheric lens), is it possible to tell Zemax to perform a raytrace but only draw rays that eventually land on the focal plane? A lot of the rays it's emitting from the source are being "wasted" by only emitting into free-space or the lens tube which I don't are about, and it slows the ray traces down.  Any help is appreciated. Thanks, Justin

Split NSC Rays in Non-sequential mode

I read in the "Exploring Non-sequential Mode in OpticStudio" tutorial that I need to select "Split NSC Rays" in order to see the effect of a beamsplitter in my design.However, checking the "Split NSC Rays" causes rays to split in other pieces of my design, including a plano-convex lens that I downloaded from the "How to create a simple non-sequential system" tutorial. Is my lens actually splitting the light, or is this just a side effect of clicking "Split NSC Rays?" See attached pictures.

Question about decenter tolerance of a lens inside a lens mount

Hello, I have the following scenario: A round lens has a given diameter tolerance D1 +/- delta_D1, distribution 1. The lens is glued inside a mount. The inner diameter of the lens mount has also a given tolerance D2 +/- delta_D2, distribution 2. This clearance fit implies a decenter tolerance of the optical axis of the lens. The position of the lens inside the (larger) mount should be uniform distributed. In Matlab I would simulate this the following way: 1. Calculate random number for D1 +/- delta_D1, distribution 1 2. Calculate random number for D2 +/- delta_D2, distribution 2 3. Calculate difference between both random numbers and devide result by 2 =: X 4. Calculate random number for +/- X, uniform distribution. This is the random decenter of the optical axis of the lens How can I simulate this correctly in Zemax? Can I simulate this with standard tolerance operands? Or do I need to work with tolerance script?  Does anybody has an idea?

Scattering analysis of transparent objects with VDI roughness surface finish

Please, can anybody help with simulating different roughness surface finish expressed in VDI / Ra? There is some plate made of Polycarbonate and has transmittance of 90%. I need to evaluate scattering of light depending on different roughness surface finish of one of the object faces. The factory can provide only VDI data. How can scattering be modeled knowing only VDI values?  Thanks

Gaussian Gx, Gy and M2

I'd like to model a flat top laser beam using the non-sequential source ellipse.  The laser beam has a central wavelength of 1064 nm, an M2 = 5 (called "M squared" or beam quality parameter", a diameter of 11 mm, and a divergence of 3 mrad.  My problem is that the source ellipse is defined in terms of the Gaussian Gx and Gy parameters, and I'm not sure how they relate to the M2 value or the divergence.  Can anyone explain how to use Gx and Gy to represent a laser beam of the parameters that I just mentioned?

Fastest Method for Implementing a User Defined Operand

I'm looking for the community's input/experience on the fastest method for implementing a user defined operand. Are there any appreciable differences between using a compiled DDE or ZOSAPI operand vs the macro language? I know this will be dependent on the specific calculation involved, but I'm more curious about any fundamental differences between the methods in terms of the speed of passing data back and forth between ZOS and the operand computation. Thanks for any responses.

How to make parametric simulation of non-sequential model.

Hello, I would like to solve a parametric non-sequential model, where I change certain geometrical parameters. At the moment I do this manually step by step, saving one model for every parameter setting. I'm sure there is something that allows for automatic batch calculation of these parameters. Best would be to have all solutions in one model and the ability to switch between these results. I know there are the options Slider, MC Editor or ZPL-Macros. However, In Slider I cannot set the increment between the parameter steps, which gives me way too much solutions I don't need and which take lots of time to calculate. For MCEditor and ZPL-Macros I could not find any useful tutorial allowing me to learn these topics in rather short time. I would really appreciate if someone could give me a starting point, how to solve this problem with a rather handy solution. Thank you for reading, Clemens

projection of an off axis object onto a hemispherical surface in squential ray tracing

Hi all, We have an object with 13.6mm height , a convex spherical mirror with 60mm diameter and 45mm radius of curvature and a 2 feet diameter hemispherical surface (Radius of curvature 1 feet). Here I'm attaching the optical lay out of the system. The object has to be projected onto a 2 feet hemispherical surface using a convex spherical mirror. The mirror has to be placed at a height of 270mm from the optical axis of hemispherical surface.  How to simulate using sequential ray tracing in zemax?  Thanks & Regards, Kabeer

ZOS-API - POP Analysis - Display Tab - MODIFYSETTINGS - parameters

I'm looking for a description how to access the parameters in the display tab of a POP Analysis in a ZOS Application. In particular, I want to save the output beam on all surfaces to a specific file. What are the parameters which need to be set in the cfg file via the MODIFYSETTINGS command to accomplish that? In the help pdf file only descriptions for the parameters in the other 3 tabs of the POP analysis window are given. Or is this not possible? Thanks, Dirk

[FAQ] What happens to the polarization when a ray passes Paraxial Lens

When a ray passes a real lens, it's obvious we should just follow the Fresnel's equation to calculate the change to the polarization (electirc field). However, the Paraxial surface in sequential mode and Paraxial Lens object in non-sequential mode are ideal optical element. They only describe how the rays' direction is changed, but what happens to the polarization state.

Update ZPL Windows

Good afternoon, I have a ZPL macro which performs a couple of very quick calculations.  Ideally I'd like to have the macro update automatically when I edit the lens data, the way other windows do.  I don't care if it's in the text viewer, graphic viewer, or some as-yet-undiscovered ouptut. But at the moment I can't find any way to have my macro re-run on changes except by clicking the "Update" arrows on the Text Viewer window directly I can see why Zemax might want to avoid this, as it could quickly create a never-ending loop if the macro itself makes any changes.  However: there is a tick box called "Update ZLP Windows" in the Visual Optimizer  that gives me some hope that this is possible.  However, checking/unchecking that box doesn't seem to have any impact, and I can't find any reference to it in the documentation.  Evidently it's a new option, as it's not shown the screen capture of the window in the help file. Does anyone have
