Workbench to integrate pyoptools with freecad, that means basically optics ray tracing capabilities for FreeCAD.

Requirements

It requires a working FreeCAD with python3 support, and pyoptools installation for python3.

Linux Installation

Clone directly the git into the Mod dir in your FreeCAD root directory, that usually means cloning into ~/.FreeCAD/Mod directory.

After that you just select the "pyOpTools" workbench in FreeCAD in the usual way. As seen in the following screenshot

Small Instructions

Please have in mind that this is a work in progress, so it may change radically some day, and your simulations may not run anymore.

The idea behind this workbench is to be able to simulate (by raytracing) optical systems. To do so, you need to build the optical system you want to simulate.

To build the system first change to the pyOpTools workbench. You will find 2 new menus:

Add Component
Simulate

The first menu allows you to add optical components to your system. Each component creates a dialog that can be used to position it, and also to adjust it's parameters such as focal length (for example). There are also some kind of ray sources that must be added to perform a simulation (point source, parallel source). After all the components and ray sources are located in the system, press simulate-> propagate, and the ray tracing simulation will be ran.

Stray light analysis

Hi guys,

I'm searching for libraries to make optical design like: Lighttols, Opticstudio or RayJack One? pyopttools seems to be perfect start point, stray light analysis can be done?

Thanks

PointSource bug

The parallel ray source was not well defined, it was defined in freecad-pyoptools using a direction vector but pyoptools uses an rotation vector. This is fixed now, but need to check because point source may have the same problem.

Hey cihologramas, thank you for your amazing work 💪. I partly used your code to make a simulation of a laser prism scanner and made a video of it here. Hope you find it inspiring 🙏 , https://youtu.be/kekMkjqzRjE

Add to the FreeCAD-addons repo for more streamlined installation

Open an issue up in https://github.com/FreeCAD/FreeCAD-addons to request adding this WB when you feel ready. Thanks. Also don't forget to give DeepSOIC a heads up regarding your work, see https://forum.freecadweb.org/viewtopic.php?t=7748
