Hi,I’m trying to model lens array imaging using mixed mode (array defined in NSC).My question is, how valid is the Image Analysis for such a setup? The on-axis field component appears to shape a proper image, but from the layout rays I have a hard time imaging how an actual image is formed (see below picture). When using the off-axis field to make the Image Simulation, the picture appears to have multiple overlays (4). Second question (perhaps the reason behind my misunderstanding), is how can Microlens Arrays be used to form images. I would think that placing the object and image plane 2f before and after the array would give a 1:1 imaging of the object (f being the single lens focal length). Additionally, I’m guessing some kind of post-processing of the image is necessary to actually make the image resolvable? Simulation file is attached.Best regards,Ahmed
What's the difference between Sequential and Non-Sequential Mode? When should I use one over the other?
I would like to use lenses from Thorlabs to collimate the NA=0.22 beam to around 0.4mm size. What merit functions should I use to achieve this goal? Can I also use Stock lens matching and merit functions together to achieve this goal?
Dear Sir/Madam,Happy New Year!I am trying to simulated the fiber with NA 0.22. For this I have taken Core RI 1.49 and claculated the cladding RI for desired NA, it is coming 1.473. I have used the formula NA = sqrt(core_RI^2 - cladding_RI^2).I am using “cylindrical volume” to simulate the fiber in non-sequential mode. Is this the right approach to have a fiber with desired NA in Zemax? Doubting because…...When I changed the NA of fiber to 0.5(core RI 1.45 - cladding RI 1.3610), just to check wheater coupling efficiency is changing or not. I am getting same power at detector, placed at front surface of fiber! and hence same Coupling efficiency.I am attaching the zemax file of my Simulation for your reference.A comment would be appreciated.Thankyou.
Coordinate Breaks are a powerful tool to model off-axis and other non-rotationally symmetric systems. However, specifying parameters like arbitrary pivot points in 3D space is non-trivial in a sequential-based coordinate system. In this OpticsTalk, we'll take a closer look at setting up Coordinate Break surfaces and utilizing functions like the Coordinate Return and different Solve types to more efficiently set up complex systems. This talk is hosted by Angel Morales, an optical engineer from Zemax's US Customer Success Team.
An interesting problem has surfaced as the Zemax team at Ansys continues to develop toolsets to aid the simulation of small form-factor, wide-angle systems such as cellphone camera lenses. Different ways exist to set up and model a stop with a lens traversing its aperture, but which is the best way? With this post, we share our recommendations and seek your feedback based on your experiences tackling this challenge.Virtual propagation modeling is one of the ways to model these stops. Technically, the portion of the lens that goes through the stop will modify the wavefront before the stop limits the wavefront with its clear aperture. Therefore, we cannot use virtual propagation to model these stops because we will be adding non-real pupil aberrations to our optical systems since we are forcing the entrance pupil to be flat when it is not.Here is an example of a stop with a lens going through it.By definition, “the aperture stop is the aperture in the system that limits the bundle of lig
ZBF stands for Zemax Beam File. This format is used in POP to describe the beam at a surface.To create a ZBF text file manually, here are two useful documents:- an Excel sheet that summarizes the syntax of the Help File (The Analyze Tab (sequential ui mode) > Laser and Fibers Group > About Physical Optics Propagation > Defining the Initial Beam > File (defining the initial beam) > Zemax Beam File (ZBF) text format > Zemax Beam File (ZBF) text format). The G column of the tab "ZBF" of the Excel sheet is a ZBF file. To create a ZBF file, copy that column into a text file and save it with a ZBF extension under \Zemax\POP\BEAMFILES. The two other tabs represent and plot the data as a matrix.- the ZBF text file created from the Excel sheet History:Date Version OpticStudio Version Comment 2019/05/20 - - Creation 2020/09/04 v2 - Updated the Excel file with non-zero imaginary profile. 2021/01/06 v3 - In the Pivot_Table tab, there are now 3 colum
Share your tips & tricks for efficiently using OpticStudio with the community! There are lots of little ways that we adapt our use of OpticStudio to streamline our work. These are usually learned over time, from colleagues, or from technical support, but they aren't typically found in other product education resources. You might have a favorite keyboard shortcut, saved settings for a particular analysis, a macro that automates 3 steps in your process tied to a hotkey, or a million other ideas. Help your fellow OpticStudio users and learn some new tricks yourself.
Hello! Apple recently introduced a Macbook with a new “M1” CPU, rather than the usual Intel CPU. This new CPU requires that any software written for standard Intel or AMD processors has to either be re-written for the new CPU or emulated via virtual machine software such as Virtualbox, VMware Fusion, or Parallels. Zemax products (OpticStudio, OpticsViewer, and OpticsBuilder) are WIndows based rather than native Apple applications, so they will not be rewritten for the M1 CPU. Zemax software has worked fine with virtual machines on Apple computers in the past. However, as reported by some Zemax customers, it appears that Parallels is still in Beta on this platform, and that there is also a “preview edition” of Windows 10. Zemax uses Thales (formerly Sentinel) licensing technology which does not support preview or beta editions of Windows 10. This means even if Opticstudio installs, you cannot access a license (either a black USB key red key , green key, or software-based (softkey) lic
Hi there, I just have some queries about using merit functions to determine the z-distances between the components within my light path, to create both a focused and a collimated light path (see image 2 below). Overview of the light path design: At the moment I have a stripped back version of my final light path (see image 1 below). It includes a UV LED operating at a wavelength of 0.233, an Edmund Optics lens (imported from the 'Lens Catalogue'), and a detector rectangle. My objective is to use the merit function to determine the z-distances between each of these components to generate a collimated light path and a focused light path. A photodiode has not yet been chosen so I currently need to know where to place my components for a collimated path (larger diode) or a focused path (much smaller diode). At the same time, I want to be able to get the most power possible at the detector. I was just hoping to gain some advice and insight into the best m
Hello, I have a built up system with lenses and mirrors and I want to build merit function which optimize the spot size in merit function. I am not sure which operands and how I could adjust them in merit function inorder to optimize my merit function where the target is spot size. Thank you
Hi,Can you please explain what Apodization Factor means?Lets say my Entrance Pupil is 25 mm and Apodization Factor is 6.5, what is the beam size?Thanks, talimu
Can I model and optimise a sequential cylindrical surface somehow? Or is it just a non-sequential option as they are obviously not rotationally symmetric.
To model a diffuse surface in OpticStudio, you need to add a Lambertian scatter profile to the face of the object. Lambertian scattering will give the rays an equal probability of scattering anywhere in the unit circle - most diffuse surfaces are nearly Lambertian. The Lambertian scatter profile can be entered under the 'Coat/Scatter' tab in the 'Object Properties' of the object you would like to make diffuse. Make sure you choose the correct 'Face' that you would like the scatter profile applied to. The 'Number of Rays' effects how many scatter rays will be generated. The scatter fraction will be the amount of power from an incident ray gets transmitted into scattered refelction/transmission vs. specular reflection/transmission. For example, if the scatter fraction is 1, the specular ray will receive zero energy and will no longer be traced; and all the energy will be divided equally among the scattered rays. If the frac
HiI tried to understand the Ray Fan in OpticStudio and ran into this problem I have a paraxial lens imaging an on-axis object (zero height) with 10 mm semi-diameter pupil size and focal length of 50 mm. Image plane is shifted 5 mm away from the focus intentionally, so it is at 105 mm from the lens. The Ray Fan plot is like this Defocus term is the slope of this line and equals 0.05. Considering the defocus formula DF = focus shift x marginal ray height (10 mm) / focal length (50 mm) gives a 0.5 mm focus shift instead of 5 mm. I am not sure if I have problem with the definition of defocus term or with interpreting the Zemax data. Any idea?
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).

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
