solving for arrangement?

[BMaxV]

Hi! love the project, pretty much what I'm looking for.

My use case is that I'm probably going to get cheaper off the shelf components, the downside is that I don't know exactly how to position them.

If the solver could do something like, given:

input ray, lens1, lens2, desired output ray -> position, rotation for lens1, lens2

that would be amazing. I'm not sure if the current solver can do this, if you already know and could write a quick example that would be optimal, otherwise I would look deeper into the code and try to get that to work myself.

Hi BMaxV,

Glad to see you love this project! The current solver cannot do it. If all of your optics share the same optical axis, and your beams are para-axis, this should be easy to calculate.
My tool is purely numerical from its start, so it didnt involve any solver. However, you can easily implement a numerical solver, by using this as a ray-propagation engine.
If you care about how moving the input ray will alter its output ray, i have a ABCD matrix solver, see https://github.com/tim4431/optable/blob/main/optable/optical_table.py Line 211. However i dont have a solver that solves the gradient wrt to moving a optics.

Best,

Hey,

quick update, I looked at the math involved and it's surprisingly easy? I will write a PR to add a little solving function for my use case eventually. I haven't done all the math and setup for my project yet, but I will need to write the code for that and will share it when I'm done.
