Can you say "Consumer Products Safety Commission" and "Melvin Belli" real
fast together about thirty times, re: commercial portable CD Players???
I have no intention of staring into anything else till I have measured its
output to my satisfaction! Now, wasn't that stupid of you? There is such a
thing as the most troublesome nightmare to the CD industry, and then there
is having no sense! Knowing the current state of tort law, I'll trust the
scared executives and their lawyers!!! You can BET those lasers are
"eyesafe"! As for the others, I have used sufficient protection. I used to
do holography. I'm no dummy! You clowns try to trot out ole "unsafe at any
wattage" and it just doesn't cut it. If you can see light from off to the
side and you move and you can still see it and you move aagain and you can
still see it, what does that mean to you??? It means that a small amount of
Watts is getting spread all over hell!! And the invisible is doing the same
as the visible!!! Dispersion difference with frequency is not THAT great!!!
