[Laser] IR laser Array??? Safety Note

Sat, 11 Jan 2003 20:13:22 -0000

John
Appreciate your points and will take due care when using and operating the
devices.I do have a Mono CCD camera that I use to see the IR, so do have an
idea where it is.I also have a power meter to monitor laser  output, so I
have no excuse for accidents.

                         Thanks again
