IR cut filter frequency response

Is there any documentation available for the IR cut filter on the lenses - I see that it cuts at 650nm, but is there any more information than that? I am trying to simulate the global shutter model camera in a high-fidelity virtual environment, and while the sensor datasheet gives the response for the sensor itself the filter doesn’t seem to be documented anywhere.

Yeah, we don’t have anything other than it’s for 650nm. We don’t exactly pay a lot for these lenses. If you want documentation head over to edmunds optics and you can buy precision stuff.

No worries, I suspected as much.
