Hi fellow Zemax-ers,

I am looking to model an optical system in sequential mode with the following characteristics. I think this could be done pretty straightforwardly in non-sequential mode, but sequential would likely be more efficient.

The optical system would have a series of elements after the object before hitting a 50:50 beamsplitter (and I am only concerned about the transmitted arm in this direction)

After the beamsplitter, it would go through some series of lenses

Then there would be a mirror that could be flat or curved that would reflect the light so that it would go back to the beamsplitter

I would only care about the reflected arm after the beamsplitter

After the beamsplitter it would go through another series of lenses before forming the image

The challenge is I want to be able to tilt or decenter the flat/curved mirror (through different configurations) that reflects the light to form the double pass.

I’ve looked at examples such as the 50:50 beamsplitter but that doesn’t really have any tilting.

I’ve looked at the scanning mirror example since it models tilt well, but it doesn’t have any double passing.

If anyone has a sample file that walks through something similar and could point me that way, it would be much appreciated.
