WebSimply: photocathode sensitivity measures light conversion efficiency while other specs are more relevant as an output at the eye. You can’t see photocathode sensitivity, meaning there’s no way to properly or consistently measure it at the eye- it’s relevant in assessing a tube’s potential performance and it influences other specs.. It’s a little but like comparing …
