Hi again Zemax peeps,
I’m a little confused about the announcement on the Geometric MTF calculation in NSC mode. Has anything changed in the feature? It’s been in the code for ages.
I’m confused because Geometric MTF is still available in the Detector viewer, but it computes as 1 for all spatial frequencies. Is this a bug or a feature? Are NSDD data items -14 and -15 (x and y MTF at specified spatial frequency) affected? Do they return the actual MTF or just 1?
