Hello everyone,I currently need to model the influence of the polarization of 2 sources in non sequential mode in the context on the creation of interferences. Hence, I thought of putting different polarization components after each source in order to see the influence in the contrast of interferences when the rays propagate through the whole system. I used the component “Jones Matrix” so far, but it is more a tool in order to check if the polarization is correctly modify than something which have a real impact on the modification of polarization. I saw a post where it was recommended to use a KDP rectangular volume with a thickness to define in order to have the good polarization. However I didn't really got how to correctly define the thickness in order to have all the polarizing components I need which are a linear polarizer, a quarter wave plate or a half wave plate. To conclude would like to know how to set any polarization in non sequential mode. Hope it was clear.Best regards,Ma
Hello,I am currently modeling a dynamic zoom system constituted of two liquid lens and a lens with a fixed focal length. The goal of this system is to change the size of the gaussian laser beam entering the zoom by a magnification factor in the range [0.2,0.6], so it can be flexible between each change of magnification. My problem is the following: I want to measure the magnification in order to be sure that the system can actually work for different magnifications. I had two ideas so far.The first one is to measure the magnification of the system using the operand PMAG inside the merit function. But it is valid only in the case of a paraxial system. Using a gaussian beam I am not sure that this is the best way to measure the correct magnification.My second thought was to measure the size of the gaussian beam waist at the entrance of the system, then at the exit and finally do the division (exit/entrance) inside the merit function. However I didn’t find such operand in order to measure
Hello everyone,I have a problem when adding new lenses inside my system. I have already worked on a dynamic zoom before (the third first elements including two adaptative surface and a doublet). Now I added a mirror, and I want to add the first lens of a tube lens of a microscope, before adding the objective. (capture 1)However, I got a big error as you can see on the second capture. I have already tried to moove the stop closer to the mirror with dummy surfaces. However, it doesn’t change anything. The first error I got si in a pop up window (missed surface 21), and then: “cannot compute when chief ray cannot be traced”. (capture 2)The thing is, I already tried to do the same process without adding these lenses, but by adding paraxial lens instead. I was then able to add the whole objective after, as you can see. (capture 3)But I wasn’t able to convert this system in non sequential mode because of the presence of paraxial lens I guess. That is why I am now trying to add “real lenses”
Hello everyone,I am currently trying to model a microscope, which of course include the use of oil. I already modelled the whole system and I work now in non sequencial mode. However, when I try to put my detector near the oil, close to the specimen, in order to investigate what kind of signal I have, I got the following error: “non mirror surfaces cannot be placed in contact with solid”. It looks like the software doesn’t like when I put my detector in oil. I modelled the oil with the solve model : n=1,52 and abbe number= 58.8. Is there a way to allow the detector to be inside the oil without any trouble?Cheers,Marie Fournier.
Hello everyone,I have modelled a really basic system in order to see the impact of polarization on interference pattern formation. This system uses 2 sources of different polarizations interfering on a detector.The variation of the input polarizations states (linear and elliptical or right circular and left circular for instance) seems to have no impact at all. Is it normal? Because in theory, the contrast should vary. Is Zemax reliable for that kind of polarization analysis? Or is my setup wrong in a way?Hope my questions were clear. The system is in the attached file.Best regards, Marie Fournier
Hello everyone,I am currently trying to create a 3D interferometry model using a detector volume. I first checked that I was able to detect the interferences in 2D, before using a detector volume, as in the tutorial: How to show Detector Volume data in 3-D – Knowledgebase (zemax.com).My system uses 3 source ellipse and a detector volume of opacity 10%.However, I cannot see any absorbed flux on my detector volume, but I don’t know why. I suspect that without detecting any absorbed flux the Macro given by the tutorial cannot be run properly. Can you help me with that?Best regards,Marie Fournier.
