Hello everyone,

I have a problem when adding new lenses inside my system. I have already worked on a dynamic zoom  before (the third first elements including two adaptative surface and a doublet). Now I added a mirror, and I want to add the first lens of a tube lens of a microscope, before adding the objective. (capture 1)

However, I got a big error as you can see on the second capture. I have already tried to moove the stop closer to the mirror with dummy surfaces. However, it doesn’t change anything. The first error I got si in a pop up window (missed surface 21), and then: “cannot compute when chief ray cannot be traced”. (capture 2)

The thing is, I already tried to do the same process without adding these lenses, but by adding paraxial lens instead. I was then able to add the whole objective after, as you can see. (capture 3)

But I wasn’t able to convert this system in non sequential mode because of the presence of paraxial lens I guess. That is why I am now trying to add “real lenses”, and got the error I described before.(capture 2).

If anyone as an idea on how to correct this error, I would be really grateful.

Cheers,

Marie Fournier.
