Roy,

Although I'm not a laser expert, my understanding is that a 500 mW laser can
cause blindness.  According to the standards used by OSHA and other people,
this would be a Class 3b laser, and a long list of safety measures is
required for their use:

OSHA's Internet site is a good resource on lasers and other kinds of
nonionizing radiation:

Can you tell me if the low level lasers such as the
THOR have any harmfull effects on the user?

I don't know what information you need to tell me this
but I will tell you what the specs are:

the laser probes are from 30mW to 500mW
the cluster probes are from 19 diades to 104 diodes
frequency adjustment from 2.5Hz -CW

If this isn't the correct info, please tell me what
you need and I will get it.
