Chris, Try contacting Donald Drozdenko at HP (Aligent) at 408-435-5807. Don headed the testing / certification efforts for HP's Laser & Led products back when 825 first emerged. Another person who may be able to help is Dr. Joseph Tajnai (408)435-6331, also from HP and member of TC76.
Good Luck, George -----Original Message----- From: Maxwell, Chris [mailto:chr...@gnlp.com] Sent: Tuesday, October 17, 2000 11:34 AM To: 'EMC-PSTC Internet Forum' Subject: Laser Safety Calculations All, I too share the sentiments of another member of the group that the calculations for laser safety in EN 60825-1 are made somewhat more difficult to follow due to the difficulty of reading the diagrams and the symbols. I myself have looked at the diagrams a few times and can't figure out what symbol is representing what angle ... I would love to see a few examples and more complete descriptions of the nomenclature. Is there a text out there, either commercial or from IEC that goes through these calculations in more detail?
