For exact comparison you can search the INTERNET for examples. 720nm is still more red than infrared in my book near infrared starts at 760nm (I think my filter is 780nm and I get the bright foliage just like everybody else). You can buy cheap $10 filters to experiment and then graduate to $100 filters once you know what you want.

We further miniaturize a recently established silver-based negative-index metamaterial design. By comparing transmittance reflectance and phase-sensitive time-of-flight experiments with theory we infer a real part of the refractive index of −0.6 at a 780 nm wavelength—which is visible in the laboratory.
