Polarization - Muller Matrix

1. How to model and partial polarized light as source?2. We want to know how to enter parameter values of muller matrix since muller matrix is more generalised. In opticStudio we have option for Jones vector. Converting Jones parameter into muller is easy by using some formula but converting muller matrix into Jones needs lots of calculation and it is tedious. So how to enter parameter values of muller matrix?

I would like to know the error of how I set the Gaussian source.

Hello, I want to design a Gaussian beam (laser, coherent source) with a divergence angle of 0.3 mrad, i.e. 0.3 mm (FWHM) at the 1 meter point. w0(1/e^2) = 0.8493218 x FWHMWhen using the above formula, the beam size (1/e^2) at the 1M point was calculated to be approximately 0.510mm.Using this value and the wavelength of 13.5nm, the Gaussian source's beam size and position were calculated and entered. However, when I place the detector at the 1M point, change the Detector viewer's Data from incoherent irradiance to coherent irradiance, and use the FWHM macro, it appears to have 0.22mm. I used the FWHM macro below.ZPL Operand: Extract FWHM from non-sequential detector | Zemax Community which part of my method is wrong? If possible, can you share the files you designed?

Lenticular Sheet based Simulation

Hi,I am a student of Optics.I am trying to simulate Lenticular sheet (cylindrical lens arrays in a sheet form) based model.I am able to create a similar model in non-sequential mode (see attached file) but I am NOT able to create or configure the effect of Lenticular sheet of making things INVISIBLE in near vicinity while allowing the distant background to be visible, through simulation.Please suggest & advice as how to simulate the object alongwith background & subsequent effect from the view plane.RegardsGaurav

How to set a model for imaging at two object planes and form images on one image plane but two virtual images

Recently, many research and development are on multi focal plane image for head up display.It needs to build an optical model to simulate the case below:There are two object planes (usually two optical paths); Need to for images on one image plane (eye box) form two or more virtual images in front of a car.Usually, the sequential lens editor of zemax opticstudio is set for modeling a system with one object plane and one image plane. Could you any experienced staff tell me how to set such a model for simulating multifocal virtual imaging of Head up display.Thank you!

Why does the wavefront change as the distance to the image surface increse?

Hello,I would like to analyze the wavefront map for different zernike coeff. and I noticed that if I change the distance to the image plane (30 mm in this case for example in the figure), the whole wavefront changes accordingly and I don’t understand why.if the source is coherant, the aberration in the wavefront should not change as it propagates. if not, then what is the relation? If this means that the surce is not coherant, then how can I make sure it it?Thank you in advance.

Creating a Simulation Software for the whole Optical System

Hello,I have a question about building a simulation program to predict the optical performance of the whole optical system. The system includes LED illumination (300 thru hole LEDs and lenses), optical diffuser, optical bandpass filter for camera, line scan cameras (RGB, SWIR), camera lenses, optical beam splitter and mirror, etc.The purpose of this program is to quantitatively predict the light power profile variation, light signal level changes, image sharpness changes, image contrast changes when moving the LED working distances, LED beam angle changes, camera working distance changes, filter changes. Do you think it is feasible to create this tool for technicians for optimizing the system settings? If yes,Does the software guys need be involved? How long the project will take? Is Zemax powerful enough to fulfill this task or need other software, or the combination of both? Is there any commercial software in the market to do this?Thank you very much!

Problems with Version 22.1

Yesterday I installed the newest version of Zemax, after the that I couldn’t run Zemax anymore since everytime I started it it froze during the “Copy Data to Zemax Folder”-step Zemax does when you start it the first time after an update.A collogue of mine had initially the same problem, but in his case restarting the PC solved it.In my case the problem persisted after the restart and I got Zemax only working again by reinstalling the previous Version.Does anyone else has this problem with Version 22.1 and is there a solution.

Sending Collimated Light onto OAP

Hey all,First question here and new user of the software (~2 months). Let me know if I have violated any rules of posting.Question: I have downloaded the following reflective fiber collimator from ThorLabs and am attempting to send collimated light ‘into’ the OAP. The downloaded lens files has collimated light entering the image plane, which I do not want.My goal is to analyze the spot size/fiber coupling efficiency of this OAP if I were send collimated light onto the OAP, with a single mode fiber at the focus. How can I go about using this lens file? How can I have an infinite-finite conjugate relationship instead of a finite-infinite?Thanks,~ Luke backup link for reflective collimator: https://www.thorlabs.com/thorproduct.cfm?partnumber=RC12SMA-P01

Color rendering on detector surface

Hello everybody,I'm facing a color rendering problem on a rather complex electro-mechanical system, where I have several lights with different colors. Having to evaluate the light pollution of some details, I would need a rendering like the one generated by the color detector but with infinite focus or shaped according to the surface in question. I can't use the detector polar because it doesn't satisfy the geometric needs of the system. Do you have any idea about it?Thanks

Grid Sag Surfaces with Gradient 4 GRIN Material

Hello,I am using Optics Studio to evaluate some FEA data of an optical component (without the STAR package). I have the deformed surfaces as grid sag surfaces and am loading them in as .dat files and setup a “gradient 4” surfaces with fitted polynomial coefficients. Is this the correct way to set up this problem? I am concerned that the grid sag surface has no thickness or material and want to be sure the model is applying the grid sag to the surfaces of my Gradient 4. I have read in the documents that dummy surfaces may be needed between these types of surfaces but when entered they make no difference. I have this set up as a multi configuration such that Flat surfaces can replace the grid sags and when toggled I do see that a change in the system performance so I know the grid sags are doing something.Would love some feedback on this setup, thanks for the help

Cannot determine object coordinates error

Hello Zemax team,My question is regarding an error I met when I use a lens black box from lens vendor. As the screenshot below, I have tried to put the object to 1 meter away in front of the lens by adjusting the surface 1 thickness. However, an error as “cannit determine object coordinates” shows up once entered. How to fix this error or what’s the proper method to change the object distance at the black box? Thanks.

Custom spectrum in 'Phosphors and Fluorescence'

Hi,I created some absorption and emission spectra using the ‘Create Spectrum File’ button in the libraries tab. They both plot fine, they are simple flat spectra. However, in the ‘Volume Physics’ section of the non-sequential component editor these spectra do not appear in the list of files in their respective drop downs. Initially only one of them did, then I restarted OpticStudio and it then didn’t appear anymore.Cheers,Josh

Geometric MTF in NSC Mode

Hi again Zemax peeps,I’m a little confused about the announcement on the Geometric MTF calculation in NSC mode. Has anything changed in the feature? It’s been in the code for ages.I’m confused because Geometric MTF is still available in the Detector viewer, but it computes as 1 for all spatial frequencies. Is this a bug or a feature? Are NSDD data items -14 and -15 (x and y MTF at specified spatial frequency) affected? Do they return the actual MTF or just 1?

TCMU Tolerance

There’s a “Nominal” field associated with the TCMU tolerance. With other tolerances (like TRAD), the nominal field is populated with a non-zero value but I don’t see that nominal field being populated with regard to coating layer thicknesses. Is the user expected to input each layer thickness in the “nominal” TCMU field or is that not necessary? Thanks.

FAQ of volume hologram model in OpticStudio

Update 2021-09-24This forum thread is answer some frequently asked questions about the volume hologram model in OpticStudio.In OpticStudio 21.1, we have implemented volume hologram model for these sequential surfaces: Hologram 1, Hologram 2, Toroidal Hologram, Optically Fabricated Hologram. This allows users to analyze the diffraction efficiency with give material information. More infomraiton can be found in Help file in OpticStudio 21.1 and this knowledge base article: Simulating diffraction efficiency of a volume holographic grating using Kogelnik’s method 1. Can I make the hologram with any kind of user defined shape?When we say surface shape, it could be the substrate or the aperture. Here we will talk about both.The shape of substrate only supports Standard (conic sphere), Toroidal (cylinder), Extended Polynomial (freeform) for now, but we can investigate if users request more.If more shape of substrate are needed, except sending a feature request to Zemax product team, the fast
