autolens's Introduction

AutoLens

Automated lens design from scratch using gradient backpropagation + deep learning. This project is built on the top of DeepLens framework.

We are planning to to build AutoLens as an open-source lens design software, imaging an open-source Zemax. Other algorithms (for example, end-to-end lens design and implicit representation) will be updated in DeepLens. Welcome to join us if you are interested in optical design!

Lens Design Examples

Example automated lens design of (left) FoV 80deg, F/2.0, 4.55mm focal length, and (right) Full-frame, F/3.0, 50mm focal length.

20 random automated lens design results for FoV 80deg, F/2.0, 4.55mm focal length.

An aspherical lens with outstanding optical performance.

Question about auto_lens_design parameters

I am trying to design a len to simulate blur image and analyse the PSF. In .config/auto_lens_design.yml, I want to design my own len which has the same parameters with my real len to take blur image. The parameters are below.
focal length: 50mm
sensor diagonal length: 11mm (2/3'')
F-number: 1.4
Then I calculate the HFOV to be 6.3°, so I set the file parameters as the picture below.

However, I got an error with calculating the exit_pupil()

I change the parameters and found that HFOV>0.34 could work but FOCLEN is only 15.55mm.
Is there any restricted range of the parameters?
How can I get a len with the parameters I want?
If the auto-lens can generate lens with small HFOV and large focal length?
I am going to read the source code deeply, but I will appreciate it if someone give me the answer early.
