I've worked with HeNe tubes before. The ones I've seen are a foot to 1.5
feet in length; they are usually 1 milli-watt to 5 milli-watts laser
output
power. You would not want to get the beam directly in your eye, it could
cause some damage. I have heard that the eye very quickly turns to avoid
being damaged though.

Sign: Don't look into laser with remaining good eye.


I worked for a company in the mid 80s that sold Pioneer Laser Disc
players. A high school kid came in one day who experimented with the
laser tubes from these players. He had holes burnt into the iris of
one of his eyes. Chuck

Bull****!

A read laser does not have that much power. If it was a CD Burner - then
that could happen. With a regular CD player, the laser might damage the
Retina which is at the back inside of the eye ball, it converts what we see
into a signal that our brain decodes as an image.

I would still like to know why it is allowed that anyone can buy a handheld
diode laser under 5 milliwatts without any safeties or adult supervision.
They can do lots of damage!
