What is the typical spectral response for certain camera/lens combination?

This curve is valid for the following lenses:

IR lens, f=88.9 mm (7°)
IR lens, f=41.3 mm (15°)
IR lens, f=24.6 mm (25°)
IR lens, f=13.1 mm (45°)

This curve is valid for the following lenses:

IR lens, f=6.5 mm (80°)
Close-up IR lens, 2.9× (50 µm)
Close-up IR lens, 5.8× (100 µm)

This curve is valid for the following lens:

Close-up IR lens, 1.5× (25 µm)
