MK-898/AAS-14A Optical Filter Kit

If you know the wavelength range of the CUT 1, CUT 2 and/or CUT 3 please let me know.
I'm hoping to put these in front of some IR sensors to make a crude optical spectrum analyzer.
They are marked:
1 CUT, 2 CUT, 3 CUT, 2.0-2.8, 3.0 - 4.1, 4.5 - 5.5 & 3.0 - 12.0 (micrometers)
