Torch Lens Maker

Appearance

Hello! I'm Victor, the author of this project.
I'm looking for funding to be able to keep working on it. If you can, please consider donating or sponsoring.
Thank you! ❤️

Getting Started ​

Torch Lens Maker is code based. The viewer component, called tlmviewer, but it's only used for interactive visualization, not for inputing any data.

In general, the workflow to design an optical system is:

  • Write some python code that defines an optical model
  • Sample the model with a discrete number of light rays along each available dimension
  • Define a loss function and optimize the model parameters
  • Analyse the resulting model samples

Using Jupyter Notebooks ​

Jupyter notebooks are the prefered way to use Torch Lens Maker. After installation, You should be able to run this code in a jupyter environment, and see a biconvex spherical lens:

python
import torchlensmaker as tlm

surface = tlm.Sphere(50, 60)
optics = tlm.BiLens(surface, material="BK7", outer_thickness=2.0)
tlm.show(optics)

Embedding in HTML ​

Jupyter is not a hard requirement. Code can also be run standalone and produce a JSON formatted dscription of a system, that can be read by tlmviewer in static HTML:

python
import torchlensmaker as tlm

surface = tlm.Sphere(50, 30)
optics = tlm.BiLens(surface, material="BK7", outer_thickness=2.0)
tlm.export_json(optics, "lens.json")

And then tlmviewer can be loaded manually in HTML to render the JSON file.
