Unfortunately there isn't a way to get such a device.
- ioman 4y agoYou can find devices like this online by googling "670 nm led"
- notacoward 4y ago670nm 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.
- lm28469 4y agoYou could DIY 650nm+ glasses using photography IR high pass filters and use any kind of light sources
- scotty79 4y agoTo get ~650nm you can just put #FF0000 on phone screen. EDIT: Not sure what people object to? What do they think is the R in RGB?
- voidee 4y agoCurious 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?
