Hello,

I've been working on a project where I need to include a rectangular mirror type surface in nonsequential mode of OpticStudio. I wanted to choose a coating for it but unfortunately, it seems that I can only do that for a standard lens. However, the object I am dealing with is rectangular shaped and when using the 'Rectangle' object type, I cannot add any coatings to it. I was wondering if there was another object type that could be a rectangle and can have a coating on it?

Thanks!
