Unfortunately there isn't a way to get such a device.

You could DIY 650nm+ glasses using photography IR high pass filters and use any kind of light sources

To get ~650nm you can just put #FF0000 on phone screen.

Curious if anyone has instrumentation to measure wavelengths for something like this. For instance, I have a 60” TV. What output would a #FF0000 image produce at full brightness?

You can find devices like this online by googling "670 nm led"

670nm is indeed not hard to find, but also it looks like 660nm is even more common. Plenty of products from flashlights to bulbs to full fixtures.
