Hi,
Thank you for reaching out and detailing the issue you're encountering with your lens model.
To assist you better, could you please share the file you are working on? Having access to your model will help me understand the specific setup and errors more clearly. Additionally, if you could provide any screenshots or further details about the errors and noise you're observing, that would be immensely helpful.
Looking forward to your response.
Best regards,
Joel H. V.

Hi all:-
I am wondering whether anyone has gotten this issue before. I am modelling an 80+ degrees Field of View lens and I am trying to do ray-tracing on it past the 80 degrees point from the aperture stop. Everything works well up until 40 degrees. At this value and past this, I get errors or noise in outputs despite the lens being visibly drawn by the tool past this field of view. When I input Pup.FieldX= 40, Pup.FieldX= 40 or greater values to any lens design, I get the following error:

Dear Joel H. V.:-
I very much appreciate your quick reply and your willingness to help out! I wasn't able to attach my jupyter notebook files of the fisheye design here so I will send this on to you via your email attached in the README. Hopefully, you will find our design interesting and perhaps there is a solution to this mysterious ray-tracing and PSF generation problem.

Visibly the rays are not being drawn past this point unfortunately. Do you think anyone would know why this is? Just to give you an idea, I'm trying to do an optical system that can be traced like this: ![image](https://github.com/Garchupiter/Kraken-Optical-Simulator/assets/113525778/c20c9b2f-d419-4150-a69d-8fdaca6c4528) Source: https://www.cloudynights.com/topic/666428-lens-designreverse-engineering/page-2
