Optical Design Software

Geopter

Introduction

Geopter is optical design software based on geometrical ray tracing.

Optical design has been aided by powerful computer and professional software such as CODE-V and Zemax, though these software are too expensive for personal users.

There have been developed and distributed increasing number of optics library. One of the disadvantage of such library is to require matured programming skills to master them.

This project aims to be in mid-ground. Geopter features to be open-sorce and to put a higher priority to intuitive GUI allowing to focus on optical design process.

This project is very work-in-progress. Any contributions or feedbacks are greatly appreciated.

Getting Started

Prebuilt Binaries

Prebuilt binaries can be downloaded from Release page.

Examples

Some example lenses are stored in "example" folder in json format. In Geopter GUI, go File->Open and select a json file.

Python scripting

Geopter doesn't have its own "macro" language unlike the exemplary software such as Zemax and CodeV. Instead, the embedded Python console enables command scripting in order to automate a complex procedure. The "app" and "osys" object provide the accesses to the application and the optical system respectively. For the moment, only a few functions have been implemented.

Note

In Geopter, the array indexes(fields, wavelengths, etc) start at 0 to keep consistency with Python.

Development

Dependencies

Library	Description
Qt	widget toolkit for GUI

geopter's Issues

Question: how is the implementation validated?

Hi @heterophyllus

Thank you for this great project - is it still based on MJH Ray optics?

How do you validate the implementation in terms of correctness? I am curious as I find this is the difficult part.

Regards

CMake Error at geopter/gui/CMakeLists.txt:60 (add_executable)

Details of Improvement

Dear Author:
thanks a lot for your great efforts.I can run the release version Geopter-0.2.0,but when compile the source codes. The Qt returns :
CMake Error at geopter/gui/CMakeLists.txt:60 (add_executable):
Target "Geopter" links to target "Qt::Widgets" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?
I try to solve the problem by adding
set(CMAKE_PREFIX_PATH "D:/Qt/6.1.3/msvc2019_64/lib/cmake") as you suggested
but it fails to work in my computer.

I'm wondering how to fix this problem.

Environment

Windows 10 Qt 6.1.3

reference book

hello！Excuse me, what reference book did you use?
Thank you for your reply！

Qt environment in Windows10

Sorry to disturb you，my dear friend heterophyllus.
I had a question which this program could not run on Windows 10 x64.
It was shown followed steps：

1. First，I downloaded the exe program from release in your project.
2. Then， I installed the vc_redist.x64.exe.
3. Last， I run it with double clicked geopter-gui.exe.
   At the end， it could not run after "double click".
   So， I hope I have the honour to know whether I didnot install any other programs of Qt environment in Windows10. If it was true，please tell me to find and install them，thanks.
