If so (and I do believe so :-), then it’s for the near-infrared. 730 nm isn’t really that much and is referred to elsewhere as ‘super-panchromatic’. It’s often used for TSF; some of you may already be familiar with such films from those amusing passport photos taken behind traffic lights.

I haven’t used the film yet, but I’ve now ordered a roll of a different TSF elsewhere.
