John Reznikoff, consultant for PSA and JSA says a video spectral comparator is not available to the general public, so it cant be one because he wouldn't say it if it wasn't true.
But for autograph authentication, get a black light and save the cost.
from his bio:
The devices he (Reznikoff) uses include: the Video Spectral Comparator , a $30,000 machine which is not available to the general public.
So it is something else.
