Export .stp file without beam showing

Hi,I’m trying to export a .stp file that includes both optical components and beams for the opto-mechanical design. However, despite trying different settings a few times, I still haven’t been able to include the beams. The layout is shown below.Has anyone had experience with this or suggestions on how to resolve the issue?

Including scatter in sequential merit function

Hi All,I’m attempting to model a system where the detector surface essentially acts as a Gaussian scatterer. My merit function is comprised mainly of GENF operands to determine, after the effective scattering, the ensquared energy as seen by the detector. I know in the geometric enclosed energy analysis there is a toggle to include scattering, but I cannot find a way to get the Merit Function Editor to include the scattering into the results. This scattering has a huge impact on the ensquared energy, so I really need to figure out a workaround. Does anyone have any suggestions? Thanks,Dave.

How to set the lens aperture in non-sequential mode

I noticed that there is no option to set the aperture when creating a lens in non-sequential mode. Please teach me how to set the aperture.

How to set a wavelength bandpass filter in sequential mode?

Hi Zemaxers In sequential mode, how to set a filter like below? or is it possible to set such a layout in sequential mode?The filter has two parts, the upper area blocks 500nm and below, and the other half is OK for all wavelengths. Best regardsYANG

Soft criteria in Non-sequential merit function

I’m looking for suggestions on how to achieve soft criteria in a merit function (particularly in non-sequential mode). For example I’ve got two optical elements, and I’m trying to optimize the system for a tight focus, and one of my variables is the distance between the two objects. I’ve got a hard criterion (NPZG) in there that says that the space between the two objects must be large enough to ensure they don’t overlap. What I’m trying to figure out is how to instruct the merit function that, all else being equal, I want that distance minimized as much as possible, but not at the cost of sacrificing focal spot size. I know that I can set the weighting of a particular operand to be very small, but trying to achieve the balance of that against all the other operands, especially when the unit systems can be so radically different seems prone to problems.

non-sequential mode: hyperhemispherical object

Hi there,I try to model a hyperhemispherical object in the non-sequential mode, however, Zemax won’t let me to do so. I get an error saying “cannot create object because there are too many faces in the source objects”. I tried to use the Boolean operation and substracted a zylinder object from a sphere. This works for truncated spheres until a hemisphere results. If I shift the zylinder further and the result would be a hyperhemispheric object the error occurs. Is there another possiblity to create a hyperhemispherical object? Many thanks for your help! :)

How do you perform Lambertian scattering in IR with a UV source in NSC?

Hello,I have a source that emits ultraviolet light. The light passes through an optical fibre and then hits a material that emits infrared light in a Lambertian manner.How can I ensure that only the rays emitted by the excited surface of my cylinder are all infrared? As you can see in the image below, my source emits infrared light, which is not the case. The small disc above is a detector with which I want to see only the infrared rays of my cylinder.I tried do this according to this tutorial but I don't understand what I am doing wrong.https://support.zemax.com/hc/en-us/articles/1500005575642-How-to-model-fluorescence-using-bulk-scattering

Parallel rays approximation in Polarization Pupil Map

In the polarization pupil map help, there is a warning "WARNING: The polarization pupil map assumes the rays are close to parallel to the z-axis and only uses the Ex and Ey components of the electric field to calculate the polarization ellipse. If the rays have a significant angle relative to the z-axis, this approximation will be invalid.” I am trying to understand the following 1) Up until what angles is this approximation valid? Is it similar to small angle paraxial approximation where sin(θ) ≈ θ? 2) When rays are not parallel to the z-axis, there is going to be Ex,Ey and Ez components. Is the PPM reporting the projection of this on the x,y plane? i.e. is it reporting Ex and Ey components and ignoring the Ez component? If that’s the case, we should be able to calculate Ez using k.E = 0 since we can get the ray direction.

How do we get the New ANSYS licenses to work?

The process to get the new ANSYS licenses to work is a nightmare!They do not have record of me being under support after paying more for support that my original license cost.Noone answers the help line!The instructions are garbage and some of the links do not work.The ANSYS system has no record either.
