Hello all: I am modeling a system where the object is pivoted about Point A - lens surface-2 center. I would like to calculate the position the OBJECT such that the refracted light is normal incident at the center of surface-2 that (Point-A).

How to calculate the Object Y-Decenter and Tilt-Y required to bring the Chief Ray position from B → A?

Zemax setup (Thanks to ​@Jeff.Wilde for his help on how to model launch ray from angled facet fiber). Here in order to demonstrate the effect of refraction, I’ve used a high n_d value.

Thanks - Asuku
