I have a Hoya X1 which transmits only green and then a little IR light, it doesn't really work well as a standalone dual-band filter but if you combine it with others, the net result can be green and more infrared.

I have three different #58 / X1 filters, one (a gel which wouldn't be coated) transmits loads of IR, one hardly any with the third in the middle.

The wratten spectra of the #058 only shows the visual range, I suspect the variation in IR is down to coatings.
