Hello, Starting from the model IR Zoom Lens, 85-205mm found in Design Templates in Zemax Libraries, can you please show how to customize the model properly to have a desired EFL? I have a fixed BFL as a costraint and I have 3 number of fields from 3 to 25 degrees. Thank you in advance, any help is appreciated Onder.
I am trying to update and use a set of Python scripts. The code used to retrieve surface comments from the Zemax model no longer seems to work in OpticStudio 23.1. This code was all written several years ago, so uses the older win32com library rather than the newer preferred .NET approach, but it does still work on another computer running OpticStudio 22.1, so has something changed in the API definitions over the past year?surface_name = system.LDE.GetSurfaceAt(k).Commentdoesn’t return a string, but <COMObject Comment>, and I can’t work out how to actually get the string out of this.The script works if I replace this line with surface_name = str(system.LDE.GetSurfaceAt(k).GetSurfaceCell(1))While this fixes the problem, it’s obviously less readable, and I’m not sure why this change is needed. Any suggestions on why the original code isn’t working any more?
Hi I want to export the lens design I drew on Zemax to Solidworks. I've never had a problem with my version in 2019 before. But now, when I save it as stl or step file(in fact, it creates a file type in the form of '.stl.log' and then I delete the' log ' part.) using the CAD Files tool and open it through solidworks, nothing appears.
I'd like to model a step-index optical fiber (because I'm interested in modyfing it). I tried to do that with a Grid Gradient with 1.55 - core index, 1.45 coat index, 4.6 um - core radius, 0.1 um - \Delta t I created a Universal Plot with x - distance from the fiber face to the IMAGE surface, and y - FICL. The problem is, the plot is almost identical with the fiber modeled as a Standard surface with 1.55 index, and both models change the FICL plot drastically when length of the fiber is changed. I need to model fiber in such way, that changing length won't change simulation results. 1. Is it good idea to model step-index as Grid Gradient, or is there simpler way to do that? 2. Is FICL good enough to recognize the way light propagates through optical fiber or should I go for POP? Also, I'd like to modify the fiber, firstly, by milling a lens in its face. I went for Standard surface with some radius. There are two problems: 3. The lens is created on top of the fiber face.
Dear Sir/Madam, I would like to know how the laser pulse looks like after it is reflected by a target. Can zemax perform such a task? An example is attached. The blue one is the transmitted pulse, and the red one is the received pulse at a certain distance. I want to know the shape of the red one , i.e., the energy variation with time, through zemax simulation, is it possible? Thank you in advance! Yingjie
What gives? Anyone else see similar effects lately?
I am trying to find the best way to compare results for my system tolerances and I would like to find a good estimation of my focused spot size and coordinates changes. I would like to understand why there is a difference between the RSRE merit function value and the spot diagram value of the RMS spot radius if I am using the following : Spot diagram : use 200 rays along the width and height in the spot diagram (rectangular pattern). RSRE : have 100 rays for 1 pupil quadrant which means 200 rays along the pupil width (rectangular pattern). The RMS spot radius is : Spot diagram RSRE 1.68739222E-02 um 1.693374956387612E-005 mm = 1.693e-2 um Thank you for your help
Why does OpticStudio label results for Luminous Intensity using units of Lumens/Steradian when you set the Source Units to Lumens? I don't know anyone or any specification that wouldn't use Candela as the title for the units of Luminous Intensity if working with Photometric units. On graphs of Luminous Intensity from the analysis of Polar Detectors I always have to change the Y axis title to Candela but can't change the Peak Intensity value unit which is always labelled as Lumens/Steradian. I have to send these graphs out to customers who have specifications that are always given in Candela and not all of them are technically aware that Lumens/Steradian is the same as Candela. Please can you at least give users the opportunity to change the Peak Intensity units so that the match the Y axis title. Even better Candela should be the default Luminous Intensity unit and if users want to revert to Lumens/Steradian they sh
