That is correct.
Thanks Bart. Money sent.
If you have a moment, could I ask whether you think the the observed brightness differences between the tritium phosphors is more related to biological retinal/photoreceptor effects, or more related to the efficiency of the phosphors themselves? I notice in camera images that the "100%" greens look like they are actually brighter (more photons output, camera sensor presumably (?) not being biased toward collecting more photons of one wavelength or another), and it's harder to tell with the other phosphors.
I have an "interesting" device that passes the output of a 1x12mm green tritium lamp through a piece of orange "optical fiber" plastic. I thought this might be to excite a fluorescent dye in the plastic (some optical plastics are doped like this I guess), but then I remembered they're using a green plastic fiber for the other model, and it's unlikely they're using a BLUE tritium vial to make it fluoresce- probably the same green vial. So if what I care about is the number of photons coming out of the end of the bit of plastic fiber (forms part of a sighting element), I probably want mainly photons that are not absorbed by the plastic "bandpass filter"- hence the orange vials. If there are large differences in phosphor efficiency outside of how well their output wavelengths are detected by human eyes, this gets more complicated :laughing:
