Flip IR-PASS filters for day/night use

[Purduephotog]

Odd question but one I am not seeing an immediate answer for. I want my camera to only shoot in IR, which means I need the IR filter holder to be active during the day (not a big deal, software) but I need to put into it an IR-pass filter. Also known as long-pass or ZWB2 or ZWB3. Or deep red. Doesn't matter, just so long as I shoot IR during the day, then remove it at night for IR illumination.

I cut my own filters, so finding one pre-cut and thin would be nice, but I don't know if this is a regular thing or not.
Thanks!

what is your question?

Is there a common IR long pass filter that can be switched into a lens mount? Does this item exist or does the mount exist? Cameras that only shoot IR for (perhaps focus) reasons?

I can't tell without disassembling mine, but it appears to be about 8mm square, and very very thin for the IR-CUT filter. So an IR-PASS filter (opaque black) similar to the ZWB2 or ZWB3 would need to be the same.
